◎ 未经买方同意，不得随意向钢中添加表中未列的元素，冶炼精加工除外。采取一切必要措施以防在废钢和生产原料中带入这些元素，因为其会削弱钢的机械性能，降低钢的适用性。

◎ 在询价和订购时可商定更严格的碳含量范围。

条件	热处理或状态	抗拉强度 σ_b Mpa	屈服点 σ_s Mpa	断后伸长率或延伸率 δ %	冲击吸收能量 KV2 J
热轧中厚板：T ≤ 75mm⑥	+AT	600~800	( t ) Rp0.2：≥ 290①③ Rp1.0：≥ 330①② ③	( t ) T＜3mm：≥40③④ T ≥ 3mm：≥40③⑤	（T＞10mm） I：≥ 100；t：≥60

◎ T-厚度；l-纵向; t-横向
◎ +A=软化退火；+QT=淬火及回火；+P=沉淀硬化；+AT=固溶退火；+SR=消除应力

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 仅作指导
③ 如果在轧制宽度<300mm的情况下，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%。
④ T＜3mm时适用于标距为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。
⑤ T ≥3mm时适用于标距为5.65√S的试件。
⑥ T＞75mm，可以协商机械性能。
* 交货条件下有抗晶间腐蚀; 致敏条件下有抗晶间腐蚀（根据EN ISO 3651-2进行测试）。

◎ Temperature of solution annealing shall be agreed for simulated heat-treated test pieces.
① Solution annealing 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.
② If heat treatment is carried out in a continuous furnace, the upper part of the range specified is usually preferred, or even exceeded.
③ Lower end of the range specified for solution annealing should be aimed at the 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 Mocontents up to 3 % and a temperature of 1020°C for steels with Mo contents exceeding 3 %.
④ Cooling sufficiently rapidly in order to avoid the occurrence of intergranular corrosion as defined in EN ISO 3651-2.
