◎ 如果热加工和随后冷却的条件符合ENISO3651-2中对产品机械性能和抗晶间腐蚀性的要求，则可以省略固溶处理。
*抗晶间腐蚀根据EN ISO 3651-2进行测试。在交货条件下：有；在致敏状态下：有。
① 对于连续热轧产品，可在询价和订购时商定Rp0.2(即表中σs)的最小值提高20MPa，Rp1.0的最小值提高10MPa。
② 如果在轧制宽度<300mm的带材情况下，采用纵向试验件，最小值减小如下:屈服强度-15MPa，恒定标距的延伸率-5%，比例标距延伸率-2%。
③ T＜3mm：该值适用于标距为80mm、宽度为20mm的试件，也可以使用标距为50mm、宽度为12.5mm的试件。T ≥3mm：该值适用于标距为5.65√S的试件。

◎ a=air; o=oil; w=water.
◎ 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.

⑦ Recommended for components with greater wall thickness.
