S355J2+N简介S开头的是碳钢结构钢，后面的355是指室温条件下的低屈服强度是355Mpa。J2则要求-20℃冲击，至于后面的+N的意思是相当于正火轧制而并非就是一定要正火，只是标准里面命名钢号的一种方法。S starts with carbon steel structural steel, and 355 at the back indicates that the minimum yield strength at room temperature is 355MPa. J2 requires impact at - 20 ℃. As for the latter + N, it means normalizing rolling rather than normalizing. It is just a method of naming steel grade in the standard.S355J2+N执行标准标准：EN10025。同类牌号：S235JR+N S235J0+N S235J2+N S275JR+N S275J0+N S275J2+N S275N S275NL S355JR+N S355J0+N S355J2+N S355K2 S355N+N S355NLS355J2 + n executive standard: en10025.
