◎ 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。

① 如果在轧制宽度<300mm的情况下，采用纵向试件，最小抗压强度值降低15MPa。
|
|
|
|
|
|
|
|
|
|
|
|
② 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。
|
|
|
|
|
|
|
|
|
|
|
|
③ 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。T ≥3mm时适用于标距为5.65√S的试件。
|
|
|
|
|
|
|
|
|
|
|
|
④ T＞75mm，可以协商机械性能。
