Question

Stainless steels are annealed at what temperature?

(a) 650°C – 700°C

(b) 700°C – 750°C

(c) 750°C – 800°C

(d) 800°C – 850°C

Answer 1

Correct option is (c) 750°C – 800°C

Easiest explanation: Stainless steels are hardened by constant heating and cooling and the best method suited for this alloy is electric butt welding. As soon as the stainless steel alloy is electric butt welded, it needs to be annealed at a temperature in between 750°C to 800°C.
