431 Stainless Steel Sheet Technique
Due to the potential for cracking, welding grade 431 stainless steel is challenging.
Pre-heating materials between 200 to 300°C prior to welding is advised.
431 is easily machineable with all operations like turning, drilling, etc
All machining must be done in accordance with tool type, speed, and feeds.
Type 431 SS panel is simple to bend, draw, spin, and more.
Grade 431 steel is heated to 2100-2200 F for optimal results.
Work materials at no lower than 1650 F (900 C).
Heat the 431-grade panel uniformly to between 1150° and 1200°C.
Do not soak; instead, start forging right away.
Hardening 431 can be done through heating at 980–1065 °C.
It can hold for approximately half an hour and then harden by quenching in air or oil.
Temper for the desired qualities. It can be heated to between 590° and 680°C as needed.
Grade 431 can be heated to between 620 and 660°C (1200–1500 F) and then air-cooled.
