How do you soften steel?
How to soften: Heat steel to a nice red glow (if you have a magnet handy, heat till it's no longer magnetic); if you let the metal air cool after this you are normalizing it, which will make it considerably softer. To make the metal as soft as possible, cool it as slowly as possible (by sticking it in ashes perhaps).See all results for this questionHot forming and heat treatment of duplex stainless steelsfull anneal. The part should be water quenched from the solution annealing temperature. It should not be allowed to spend several minutes in the 7001000°C (13001830°F) range while being transferred to the quench location after this nal anneal. Minimum solution annealing temperatures for duplex stainless steels are summarized in Table 2.Helpful FAQs and Stainless Steel Information from Eagle annealing stainless steel steels AssemblingStainless Steel is usually sold in the annealed condition.
