Rolling tolerances for structural steel and I and H sections

Section height (h)The deviation from nominal on section height measured at the centre of web thickness shall be within the tolerance given in table across.

Out of squareness (k + k¹)The out of squareness of the section shall not exceed the maximum given in table on page �6.

Flange width (b)The deviation from nominal on flange width shall be within the tolerance given in table across.

Web off centre (e)The mid thickness of the web shall not deviate from the mid-width position on the flange by more than the distance (e) given in table on page �6.

Web thickness (s)The deviation from nominal on web thickness measured at the mid point of dimension h shall be within th tolerance given in table across.

Straightness (qxx x qyy)The straightness shall comply with the requirements given in table on page �7.

Flange thickness (t)The deviation from nominal on flange thickness measured at the quarter flange width point shall be within the tolerance given in table across.

Tolerances on massThe deviation from the nominal mass of a batch or a piece shall not exceed ± �.0%.

The mass deviation is the difference between the actual mass of the batch or piece and the calculated mass.

The calculated mass shall be determined using a density of 7.85 kg/dm³

Tolerances on lengthThe sections shall be cut to ordered lengths to tolerances of a) ± 50mm; orb) + �00mm where min lengths are requested.L represents the longest useable length of the section assuming that the ends of the section have been cut square.(see figure at top of page �5)

Steel Explained

Chemical Elements Heat Treatment of Steel

Term Term

CARBON (C) The most important element in steel is Carbon. It is in steels which have to be hardened by quenching. The hardness and strength of materials is controlled by the degree of carbon present.

ANNEALING Softening steel to improve machinability and cold working properties by heating in a furnace holding at a suitable temperature and then cooling. This improves machinability and cold working properties.

CHROMIUM (Cr)

Hardenability is increased by the level of Chromium, it also improves resistance to abrasion and wear. An essential element in stainless steel and heat resistant materials, where up to 30% may be present.

CARBURISING Steel that is low in carbon is heated to around 900 degrees Celsius in a medium containing carbon in a solid, liquid or gaseous state. This diffuses carbon in to the surface of a steel that is low in carbon

LEAD (Pb) Machinability can be increased by the addition of up to 0.30% lead. If distribution is homogenous, it has little effect on the physical properties of steel and does not effect the weldability.

HARDENING Steel is heated to a temperature slightly above the critical range, it is then soaked at that temperature for a given time, before being quenched in a suitable medium such as water, oil or air.

MANGANESE (Mn)

A mild deoxidant, expelling the sulphur and oxygen away to the slag, it also increases hardenability and tensile strength, but decreases ductility. It combines with sulphur to form globular manganese sulphides, essential in free cutting steels for good machinability.

INDUCTION HARDENING

Components are heated by high frequency induction, then quickly quenched to increase surface hardening. Results will depend upon the carbon content of the steel, but best results are achieved on steels with a content range of 0.�0%-0.�5%.

MOLYBDENUM (Mo)

Hardenability is increased and the risk of temper brittleness is reduced in low alloy steels. When added to stainless steels it increases resistance to corrosion. It is also used in the high speed tool steels.

NITRIDING Nitrogen is introduced in to the surface of the steel by absorption, producing a very hard case. Hardness can be increased up to ��00VPN, dependent on specifications.

NICKEL (Ni) Carbon steels with up to 5% nickel have increased tensile strength, toughness and hardenability, without losing ductility. An alloying element, it is often used in combination with chromium and molybdenum. Between 8% and ��% nickel is contained within stainless steel.

NORMALISING According to analysis of the steel, it is heated to between 800-900 Celsius, held at temperature before being cooled in still air. This improves the mechanical properties, relieves internal stresses and refines the grain size.

PHOSPHORUS (P)

Its embrittling effect is often regarded as an undesirable impurity. It does however increase the tensile strength of steel and improves machinability. Phosphorus does not usually rise above levels of 0.05% in most steels.

SPHERODISING Often used for high carbon steels, it is a form of annealing. It assists machinability by creating the softest state possible.

SELENIUM & TELLURIUM (Se,Te)

A selenium content of 0.�5/0.25% is typical in free machining stainless steel. Tellurium can be added to leaded freecutting steel in levels of 0.03/0.05% to further improve machinability. The presence of both these elements improves machinability.

STRESS RELIEVING

Stresses are removed following cold work or rough machining, work must be carried out at temperatures between 600 -650 degrees Celsius.

SILICON (Si) A powerful deoxidiser, it is present in most commercial steels within a range of 0.05%/0.35%. Although Silicon Manganese Spring Steels, Acid Steels and heat resisting steels contain higher levels.

TEMPERING Following hardening, tempering removes brittleness, reduces hardness and relieves stresses. Carried out in temperatures between �50-650 degrees Celsius, the steel must then be cooled in still air or quenched.

SULPHUR (S) When steel is high in sulphur and low in manganese it can have an adverse effect on impact properties. High levels also result in poor welding quality.

TUNGSTEN (W)

Used as a main element in high speed tool sets. It enables the steel to maintain high temperatures, making it suitable for cutting tools.

VANADIUM When used in combination with other alloying elements it can improve softening at high temperatures and fatigue stress, by restricting grain growth, refining grain size, increasing hardness and resistance to shock loading.

Chemical Elements Heat Treatment of Steel

Term Term

CARBON (C) The most important element in steel is Carbon. It is in steels which have to be hardened by quenching. The hardness and strength of materials is controlled by the degree of carbon present.

ANNEALING Softening steel to improve machinability and cold working properties by heating in a furnace holding at a suitable temperature and then cooling. This improves machinability and cold working properties.

CHROMIUM (Cr)

Hardenability is increased by the level of Chromium, it also improves resistance to abrasion and wear. An essential element in stainless steel and heat resistant materials, where up to 30% may be present.

CARBURISING Steel that is low in carbon is heated to around 900 degrees Celsius in a medium containing carbon in a solid, liquid or gaseous state. This diffuses carbon in to the surface of a steel that is low in carbon

LEAD (Pb) Machinability can be increased by the addition of up to 0.30% lead. If distribution is homogenous, it has little effect on the physical properties of steel and does not effect the weldability.

HARDENING Steel is heated to a temperature slightly above the critical range, it is then soaked at that temperature for a given time, before being quenched in a suitable medium such as water, oil or air.

MANGANESE (Mn)

A mild deoxidant, expelling the sulphur and oxygen away to the slag, it also increases hardenability and tensile strength, but decreases ductility. It combines with sulphur to form globular manganese sulphides, essential in free cutting steels for good machinability.

INDUCTION HARDENING

Components are heated by high frequency induction, then quickly quenched to increase surface hardening. Results will depend upon the carbon content of the steel, but best results are achieved on steels with a content range of 0.�0%-0.�5%.

MOLYBDENUM (Mo)

Continental or European Sections

European I Beams

(IPE/IPN)

European Wide Flange Beams

(HE/HL)

European Channels

(UPN/UAP)

The IP range is very similar to the UK Universal Beams.

i.e.IPE �80 (�80 x 9� x �8.8kg/m) is similar to Universal Beam �78 x �02 x �9 kg/m

The HE/HL range is similar to our Universal Columns and bigger Universal Beams.

i.e. HEB 200 (200 x 200 x 6�kg/m) is similar to Universal Column 203 x 203 x 60kg/m

HEA 600 (590 x 300 x �78kg/m) is similar to Universal Beam 6�0 x 305 x �79kg/m

Unfortunately there are very few direct comparisons on the channel range.

General RulesWith European sections is the letter usually depicts what type of section it is.

U = channel I = beam H = columnThis only deviates on the bigger and heavier HE/HL range.

The weights on the sections are depicted by letters, with AA being the lightest. The higher the letters the heavier the section is going to be. The Channel sections are either UPN, taper flange - which is all but obsolete now in the UK, or UAP which are parallel flange .
