The tables below show the material grade S355 steel properties and specification according to EN 10025-2 standard, including chemical composition, yield strength, tensile strength and elongation, etc.

一、 S355JR 就是 BS EN 10025；S355JR相当于我国相当于我国——低合金高强度结构钢的钢号（欧标EN10025）。 其中355是指：屈服强度355MPa。 屈服强度355MPa相当于GB的Q345常说的低合金板。 JR表示该号没有冷成型等特殊要求，我国最接近的材料是： Q345B。 三、 S355J2 执行标准：EN10025，是s355j2欧标低合金钢板。 S355J2就是普通的欧洲低合金钢板，一般的中厚板钢厂都可以生产，生产标准参照EN10025即可。 仅供参考,对应需要 根据您客户的具体的 …

2024年2月14日 · S355NL是 EN10025-3:2004 标准中的 正火钢 (细晶粒钢).其屈服强度和抗拉强度和我国的Q345低合金钢对应·NL是要求在零下50度的低温环境中做冲击吸收功试验·且冲击值不小于27J. S355为欧标低合金高强度板. 钢牌号须由以下几部分构成: —本标准号 (EN10025-2); —钢名或钢号:钢名由以下几部分构成: —符号字母S (结构钢)或者E (工程钢); —有关厚度≤16mm的以MPa为单位时,其最小屈服强度的描述; —可行时,标记冲击功的质量组成名称; —可行时,标记用 …

S355, belonging to the class of structural steels or “construction steels”, is an alloy with a low carbon content, characterised by a good presence of manganese. The elements that distinguish this steel determine its mechanical properties: minimum tensile strength and yield strength, but remarkable ductility and good resistance.

S355JR，S355J0，S355J2，S355K2，S355N，S355NL都属于欧标低合金高强度钢板 执行标准为：欧标EN10025 钢坯生产厚度在8-150mm 最小吨位不低于2.5吨 其中和国标的Q355相对应 S355JR相当于Q355B S355J0相当于Q355C S…

2017年1月21日 · S355 Grades S355JR, S355J2, S355J0 and S355K2 is named based on it's minimum yield strength of 355 Mpa (N/mm2), However the yield strength reduces when you go up in thickness above 16 mm for flat products & hollow sections

S355JR, S355J0, and S355J2 are structural steel grades defined under the EN 10025 standard. These grades share common properties but differ significantly in terms of their impact toughness and applicable operating temperatures. This article aims to highlight the differences and provide guidance on their selection based on specific applications.

2015年8月23日 · S355 is a non-alloy European standard (EN 10025-2) structural steel, most commonly used after S235 where more strength is needed. It got great weldability and machinability, let us see more mechanical details of this steel. Identification of Different S355

S355JR在中国钢材是低合金高强度结构钢，硬度为70-80B，屈服强度在300-400MPa之间。

S355 Grade ranges S355JR, S355J0, S355J2, S355K2 which are non-alloy structural steel material specified in EN 10025 standard. "S" means structural, "355" representas yield strength at 355 Mpa minimum. JR specified the steel need to be impact testing at 27 Joules with logitudinal Charpy V-Notch impact test at room temperature.
