◎ Scale and annealing colours produced during hot forming, heat treatment or welding may adversely affect the corrosion resistance. They should be removed as far as possible before use, e.g. by pickling.
◎ The temperatures of annealing should be agreed for simulated heat treated test pieces.
① The solution treatment may be omitted if the conditions for hot working and subsequent cooling are such that the requirements for the mechanical properties of the product and the resistance to intergranular corrosion as defined in EN ISO 3651-2 are obtained and provided these requirements are met even after appropriate subsequent solution annealing.
② Re-crystallizing annealing.
③ If heat treatment is carried out in a continuous furnace, the upper part of the range specified is usually preferred, or even exceeded.
④ The lower end of the range specified for solution annealing should be aimed at for heat treatment as part of further processing,because otherwise the mechanical properties might be affected. If the temperature of hot forming does not drop below the lower temperature for solution annealing.a temperature of 980℃ is adequate as a lower limit for Mo-free steels,a temperature of 1000℃ for steels with Mo contents up to 3% and a temperature of 1020℃ for steets with Mo contents exceeding 3%.⑤ cooling sufficiently rapid.
⑥ Minimum holding time:30min.
