Stainless steel can be cut and profiled in the same way and using the same type of equipment as for most types of steel. The high work hardening rates of austenitic stainless steels means that tool/machinery capability and rigidity requirements are higher than for carbon steels. The techniques for sawing, shearing, plasma cutting, blanking, punching and piercing are discussed.

Duplex Stainless Steels are growing at a high rate. It is important to understand how they differ from the more familiar stainless steels and how these differences affect the fabrication methods and parameters

Both flux- and gas-shielded processes for welding stainless steels generate fume. So does plasma arc cutting. Fume consists of both particles and gases, including ozone. Concerns that fume, particularly particles containing hexavalent chromium, is a cause of cancer have not been supported by extensive studies, although there is a slight excess of lung cancers among all welders. Therefore it is sensible to limit contact with welding fume and there are statutory requirements.

Stainless steels can be readily cut using laser methods. The properties of the steel, including magnetic permeability, should not be affected by laser cutting. Any distortion experienced during or after cutting should only be due to the relief of ‘self restraint’ on cutting and not due to any changes in the material from the cutting method.
