Suitable Fabrication and Processes
X17CrNi16-2 (1.4057) stainless steel is a versatile and widely used material that can be machined, welded, and heat-treated.
Machining – This grade can be machined using conventional methods. Its high hardness & work hardening tendency can make it more difficult to machine than some other stainless steel grades. Carbide-cutting tools are recommended, and a slow cutting speed and high feed rate are often used to minimize work hardening.
Welding – X17CrNi16-2 is weldable using all common welding techniques. It includes gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), & shielded metal arc welding (SMAW).
Heat treatment – To achieve a range of properties, such as increased hardness, improved corrosion resistance, & enhanced wear resistance, X17CrNi16-2 can be heat treated.
