400 Brinell PlateThis is an abrasion resistant steel plate produced to give an optimal combination of hardness, toughness and weldability.

Suitable applications: Bucket lips • Buildozer blades • Chutes • Mine scrapers • Dump truck bed and liners • Fan housing liners • Blasting screens • Brick and tile dies • Mixer blades • Sand and shot blasting equipment • Shovel buckets.

These steels are intended for structural work where no significant forming or bending must be done. The grade should be selected depending on strength required.

Welding: 400 Brinell is readily weldable. Low hydrogen electrodes (Type EN110XX or E70XX) must be used to avoid cracking in the heat affected zone. In addition low tensile strength consumables should be used to minimize residual stress. High heat inputs will reduce the hardness in heat affected zone and should be avoided.


9

SS10/200 (Bennox)This is a high carbon, rolled, low cost wear resistant steel. This type of steel should be selected for applications where higher mechanical strengths are required.

Due to the good wear resistance obtained through heat treatment, its suitable fo farm implements such as plough beams, plough shares, scraper blades, discs, mower knives and harrow teeth.

Material is supplied with analyses certificates.


500 Brinell PlateThis steel provides maximum hardness for improved abrasion resistance. Its ideal for applications requiring high resistance sliding wear.

Hardness: The minimum surface hardness is 460 Brinell and the normal surface hardness is 500 Brinell.Welding: 500 Brinell plate is weldable with proper procedures. To prevent cracking, low hydrogen procedures and low tensile strength consumables should be used as well as extremely low heat input rates avoided.Cutting: The steel can successfully be cut by plasma, laser and hydro jet cutting techniques.Shearing and punching: These plates can be sheared in thicknesses up to 25 mm. Punching is not recommended.Bending: The bending capacity is limited: A bend diameter of at least 24 times the plate thickness should be used.

All material is supplied with test certificates certifying hardness and chemical composition. 500 Brinell Plate is sourced from renowned international mills.


ROQ-tuf® AM700This is a high strength quenched and tempered, fine-grained steel. The steel has been developed to provide an excellent combination of strength, toughness and wedability.

Cutting: Use flame or plasma cut with conventional equipment.


BS1501:430 MPa GradeThis carbon steel available in various grades is used for pressure vessels.

Available in thicknesses up to and including 100 mm.

Materials is supplied with test and analysis certificates.

LLOYD’S ship hull steel - 2001Lloyds Register of Shipping, are defined as mild steel with a tensile strength ranging from 400 to 520 Mpa. The requirements apply to steel plates not exceeding 30 mm in thickness. Four grades are specified, namely A,B, D and E. Although these grades have the same tensile strength, they are characterized by an increasing degree of toughness.

The higher strength grades of steel are the grades with a minimum specified yield strength equal to or in excess of 355 MPa. Three grades are specified namely AH36, DH36 and EH36. The higher strength grades have a minimum tensile strength of 490 MPa.

Welding: 400 Brinell is readily weldable. Low hydrogen electrodes (Type EN110XX or E70XX) must be used to avoid cracking in the heat affected zone. In addition low tensile strength consumables should be used to minimize residual stress. High heat inputs will reduce the hardness in heat affected zone and should be avoided.

Pickling and OilingThe hot rolled coil passes through a pickling line where rust acid removes scale arising in the hot rolling process. After pickling, the steel is thoroughly rinsed, dried and oiled to prevent atmospheric oxidation before cold rolling. Available upon request.


Cold Rolled Flat Sheets

Corrosion PreventionCold rolled sheet, when not adequately protected, is susceptible to corrosion, the user is advised to take the following precautions:a. Cold rolled sheet can be ordered as follows:

i) With a rust prevention oil. The protective oil, which is used to treat rolled sheet, has a mineral oil base with resistance to corrosion, staining and emulsification. It can be removed by using conventional hot alkaline cleaning methods or solvents. The oil is compatible with drawing compounds in common use for drawing and pressing operations.

ii) Treated with a skin passing / wet temper corrosion straining fluid. The fluid is not compatible with paint systems and can be removed by conventional hot alkaline cleaning methods or solvents. A corrosion free strip cannot be guaranteed due to the limited corrosion protection provided.

iii) Hard, un-annealed without rust preventative oil, but with a thin layer of residual rolling oil. (Not adequate to guarantee products free from rust)iv) Dry without any temporary surface corrosion protection and no guarantee against corrosion is provided.

b. Store the sheet under low humidity (less than 40%) and constant temperature conditions. High humidity accelerates corrosion. stagnant air, which is subjected to changes in temperature, precipitates moisture and consequently, corrosion of the sheet takes place.

c. If it is impossible to control humidity or temperature or temperature, the sheet must be stored where good air circulation exists.d. When bundles of coils have been opened the material must be used with a minimum of delay.e. In the event of material coming into direct contact with water, it should be treated with an approved dewatering oil and used as soon as possible.

Available Surface Textures:a. Smooth (plating application)

It is suitable for electroplated articles and also for re-looing when a matt texture is undesirable. A maximum surface roughness of 0.5 micrometers centre line average (CLA) is aimed for, typical applications are car bumpers, door locks and other electroplated articles.

b. Light matt (drawing and pressing applications)This surface is characterised by a fine, closely packed sharp texture. A surface roughness of 0.60 - 1.25 micrometers centre line average (CLA) and 100 peaks per inch (PPI) minimum is aimed for. Typical applications are automobile panels.

c. Medium matt (drawing and pressing applications)A surface roughness of 0.8 - 1.6 micrometers centre line average (CLA) and 100 peaks per inch (PPI) minimum is aimed for. Typical applications are drum bodies and ends.

d. Normal (general applications)A surface roughness of 0.8 - 2.0 micrometers centre line average (CLA) and 90 peaks per inch (PPI) minimum is aimed for. Typical applications are steel furniture and general sheet metal work.

e. Matt (drawing and pressing applications)The surface texture relatively rough to ensure lubricant retention during drawing and pressing operations. A surface roughness of 1.2 - 2.0 micrometers centre line average (CLA) and 100 peaK per inch (PPI) minimum is aimed for. Typical applications are automobile panels, engine mountings, brackets and enamelling.

GALVANIZED SHEETHot-dip galvanized sheet is produced on continuous zinc coating lines from either cold rolled (thickness range 0.30 mm to 2.0 mm) or hot rolled (thickness range 2.01 mm to 3.0 mm) steel substrate, in coil. The galvanizing process yields homogeneously zinc-coated sheet with a bright, smooth metallic finish.The zinc coating can be supplied with a normal or flattened minimised spangle finish.Zinc coatings of different thickness may be ordered to suit specific end-use requirements. The thickness and type of steel substrate are selected on the grounds of mechanical and structural considerations.

The following zinc coating surface finishes may be ordered to suit specific end-use requirements:1. Normal or Regular spangle is supplied for a wide range of applications where over-painting for

maintenance purposes may be undertaken at a later stage.2. Flattened minimised spangle: This finish is recommended for applications where a high gloss paint finish is

required. It is available for zinc coatings of mass up to Z275, and a maximum material thickness of 1.20 mm if passivation is required, or a maximum thickness of 1.60 mm if passivation is not required.

Please note: Lockforming quality Z275 is not a stock item and can be ordered on request (subject to leadtime at time of enquiry).

ELECTRO-GALVANIZED SHEETElectro-galvanised steel sheet consists of a cold rolled steel substrate coated with zinc by electrolytic deposition on a continuous line. The electro-galvanizing process not only allows accurate control of the thickness of the zinc coating, but also permits the coating of either one or both sides of the sheet, and the coating of different thicknesses of zinc on the two sides of the sheet.

Electro-galvanized steel sheet is intended for applications involving all forming, drawing, stretching and bending processes during the manufacture of articles. A range of coating thicknesses is offered with a corresponding increase in corrosion protection.

The maximum coating thickness is equivalent to that of a Z100 hot-dip galvanised sheet. The selection of the thickness of the zinc coating depends on the specific requirements of the application.

Chromadek® Sheet & Colour Chart

Chromadek® Chromadek® for interior applications is available as hot dip galvanized steel sheet which is pre-painted on Arcelor Mittal Steel South Africa’s coil coating line with special high quality paint coatings. Chromadek® is a finished material with decorative coatings with good general abrasion resistance, but must be handled with care to prevent damage to the coatings.

Welding: Many joining techniques are now available as alternatives to the more traditional methods. Pre-painted materials can not be welded by traditional methods as the coatings do not conduct electricity and are damaged by heat.

Forming: Roll-forming rather than press braking is recommended for the forming of sections and components from pre-painted steel sheet, since there is less chance of damaging the paint coating.

Packing: Protective strippable films are available when required for applications where appearance is of prime importance.

Material Specification: A classification of external and internal environments is also important in determining the more suitable material to be utilised. External environments can vary between coastal and rural and also polluted and unpolluted. Interior environments must also be assessed because a build-up of pollutants or fumes could result in premature corrosion on the inside surfaces.

Ordered Thickness: This is the steel plus zinc coating, but not paint coating i.e. 0.50 or 0.58 mm galvanized thickness.

Grade: The mechanical strength of the steel substrate is expressed as the minimum yield strength values and is measured in megapascals (MPa).Low strength steel may be rated as ISQ 230 and as the yield strength increases, so co the values, with intermediate strength of ISQ 300 and an ISQ 550 having the highest strength.

Span: This is the distance between the roof purlings, as recommended by the roll-former, with the values varying according to each particular profile.
