High strength steel plates, despite their high strength, offers outstanding workability. However, it is recommended that the manufacturing process should be taken into full consideration in order not to impair mechanical properties.

High strength steel plates can cutted by such conventional methods as gas cutting, plasma, laser and water-jet. If you using gas cutting use the right nozzle to minimize the heat affected zone.


Should not be punched for holes. Drilling is recommended. High strength steels can be gas-cut as easily as mild steel. Gas cutting produces a hardened layer up to 2mm in depth. When bending plates, particularly those of 60Kg/mm2 or higher tensile-strength steels, removal of the hardened layer by grinding or other method is recommended. Gas-cut edges supposed to be welded do not require this removal since the hardened layer is removed by the weld penetration.
