S355JR steel (1.0045 material) is one of the quality grades in S355 steel group, the steel has a minimum yield strength of 355 MPa (51 ksi) when the thickness is ≤16mm, and the minimum impact energy 27J at room temperature 20 °C (68 °F).

Steel grade S355JR is used to manufacture hot-rolled flat and long products, which are subsequently used when producing steel building structures. Classification: Non-alloy structural steel. Products: Flat and long products, semi-finished products.

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 …
