At the time of hot forming process, throughout the whole workpiece heated, to 2,250 1750 ° f ° f temperature range, 2,205 alloy at this temperature very soft. If the temperature is too high, 2,205 alloy easy to hot tearing. Below this temperature, austenite fracture occurs. When less than 1700 ° f, due to the influence of temperature and deformation, metal meeting soon between formation. Hot forming finished immediately on its low for the 1900 ° f temperature solution annealing, quenching and to restore its phase balance, toughness and corrosion resistance. We do not recommend for stress relief, but if this must be done, materials should be carried out in a minimum of 1900 ° f temperature solution annealing, and then rapidly cooling, water quenching.ASTM A167-99 stainless steel 316 steel sheet
