Steel

Modern plasma and laser beam cutting methods for the thermal cutting of heavy plate to make parts orcomponents offer a number of advantages over conventional oxy-fuel flame cutting:

Ø  Higher cutting speeds on thin plates

Ø  Improved edges

Ø  Smaller heat affected zone at the cut edges

Ø  Less distortion in the parts.

The increased use of sensitive and highly advanced plasma and laser beam cutting machines places particulardemands on the plates. These include:

Ø  Good surface quality

Ø  Good flatness

Ø  Low residual stresses

Ø  Good steel cleanliness

Ø  Close tolerances on chemistry and mechanical properties.

LaserCut plates from ThyssenKrupp meet these demands. They are available as plates cut from hot-rolled coil andas quarto plates in the following important steel groups:

Surface condition and tolerances, minimum order quantities

1.  Coil plates:

By agreement at the time of ordering the plates can be supplied in the following surface conditions:

- As-rolled- pickled and oiled (3 to 6 mm thickness, maximum width 1650 mm)- shot blasted and primed (7 to 10 mm thickness).

Width tolerance: -0 / +3 mm.Length tolerance: -0 / +5 mm.

Marking of quarto plates (and primed coil plates):

Paint marking of quarto plates: Die stamping:

Plate number or coil No.Code / order and item / plate No. / grade name-LC

General information

Our high-quality LaserCut plates are handled with the utmost care in our plants. After shipping, the plates /bundles should also be treated carefully and properly during stacking and handling to rule out negative effects on

processing properties (flatness / stresses).

As with all cutting processes, high cut quality at highest-possible cutting speeds requires careful matching of allcutting parameters.
