Modern plasma and laser beam cutting methods for the thermal cutting of heavy plate to make parts or components offer a number of advantages over conventional oxy-fuel flame cutting: Higher cutting speeds on thin plates Improved edges Smaller heat affected zone at the cut edges Less distortion in the parts. The increased use of sensitive and highly advanced plasma and laser beam cutting machines places particular demands on the plates. These include: Good surface quality Good flatness Low residual stresses Good steel cleanliness Close tolerances on chemistry and mechanical properties. LaserCut plates from ThyssenKrupp Steel meet these demands. They are available as plates cut from hot-rolled coil and as 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/+6 mm. Reduced flatness tolerance according to EN 10029: Plate thickness 3 < 5 mm : max. 4 mm/m flatness tolerance, Plate thickness 5 mm : max. 3 mm/m flatness tolerance. Other tolerances (thickness, weight, squareness, camber): according to EN 10051. Minimum order quantity: Coil yield, i.e. 15 to 30 t depending on grade and size. 2. Quarto plates: The plates are supplied shot-blasted and primed (Zinc silicate shopprimer, coating thickness 12 - 20 µm). Tolerances to EN 10029, Reduced flatness tolerance to EN 10029: max. 3 mm/m.

Recommended marking and packaging

1. Coil plates: The plates are given an ink marking consisting of: manufacturer's symbol, coil number, short name with extension "LC". Die stamping on primed plates, otherwise only if ordered explicitly or required by specifications. For paint marking of primed coil plates see "Quarto plates" section. Label: per bundle 2 labels on metal carriers on strapping. Packaging: according to packaging options for ThyssenKrupp Steel product mix.

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 all cutting parameters.
