EN10210 S355J S355J2H Hot Rolled Seamless Carbon Structural Steel Pipes
1. Product Description: EN10210 S355J and S355J2H Hot Rolled Seamless Carbon Structural Steel Pipes are designed for structural applications where high strength and durability are required. These pipes are manufactured through a hot rolling process, which involves rolling the steel at high temperatures to achieve the desired shape and dimensions. The 'S355' designation indicates the minimum (yield strength) of the steel, which is 355 N/mm².
