It is a stable austenitic stainless steel developed on the basis of steel by increasing the nickel content. Since martensitic transformation does not occur after cold deformation, the possibility of work hardening is small& In cold forming processing, the number of intermediate annealing (softening) can be reduced and the processing cost can be reduced. The cold and hot processing properties of steel are excellent, and the welding performance is good.
Feature application:
In order to ensure the corrosion resistance after welding, It is recommended to carry out solution treatment after welding. Stainless steel is most suitable for cold piercing, deep drawing, press forming and other processed parts, and is especially suitable for non-magnetic cold-worked parts. Compared with austenitic stainless steel, the work hardenability is low. Usage: Spinning processing, special drawing, cold heading.

Metallographic structure: The structure is characterized by austenitic type.
The nickel content in stainless steel is high, so the austenite is relatively stable, martensite transformation will not occur after cold deformation, and the tendency of work hardening is small.
Processing performance:
Stainless steel has excellent cold and hot processing properties. It is easy to forge and roll in hot processing. It can be cold processed on various products. It has good welding performance and has the same welding characteristics as steel.
The thermal processing temperature is ~°C during heat treatment, the solution treatment temperature is ~°C, the heat preservation water cooling, stress relief annealing temperature is ~*(~), and air cooling.
Corrosion resistance:
The corrosion resistance of stainless steel is basically the same as that of steel, except that the carbon content in steel is higher than that of steel, so the intergranular corrosion resistance is slightly worse. In order to improve the resistance to intergranular corrosion, the steel should be solution treated.
