*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.
② 如果在轧制width<300mm>
③ T<3mm:该值适用于标距为80mm、width为20mm的试件,也可以使用标距为50mm、width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. ◎ The temperatures of annealing should be agreed for simulated heat treated test pieces. ① Solution annealing in the range specified followed by sufficiently rapid cooling to avoid precipitation of deleterious phases is essential after hot forming these steets. ② If heat treatment is carried out in a continuous furnace, the upper part of the range specified is usually preferred, or even exceeded.
