201 stainless steel is a type of chromium-nickel-manganese austenitic stainless steel, which is widely used as a cost-effective alternative to 304 stainless steel in less corrosive environments. With moderate corrosion resistance, good formability and weldability, and a low nickel content, you can find equivalents in various steel standards. Such as X12CrMnNiN17-7-5/1.4372 from the European standard EN 10088-3, 12Cr17Mn6Ni5N/1Cr17Mn6Ni5N from the Chinese standard GB/T 1220, SUS201 from the Japanese standard JIS G4303, and 12Kh15G9ND from the Russian standard GOST 5632-72, etc.

6：Steel making & Forging processing
1): Steel making process:
EF+LF+VD
EAF+LF+VD
EF+LF+VD+ESR
EAF+LF+VD+ESR
2): Forging processing:
Hot forging temperature: 850-1150℃. Slow and uniform heating to the starting forging temperature is required to avoid thermal stress cracks.
Cooling in the air
7: Heat treatment
1）: Solution annealing
Heat 201 steel to 1010-1120℃
Quick cool in the air/water
The aim is to optimize corrosion resistance and plasticity by eliminating work-hardening, dissolving carbides and restoring single-phase austenitic organization.
2): Aging
Heat to 850-930℃ in the furnace
8：Application

2) Elevator decorative panels, curtain walls
3) Interior skirting, ceilings and suspended ceilings
3. Industry & Manufacturing
1) Automobile exhaust
2) Home appliances Shell: washing machine, refrigerator, microwave oven, etc.
