The capital letter H in S355J0H and S355J2H stands for ""Hollow section"", which respectively represents the pipe of S355J0 and S355J2.The Executive Standards of S355J0 steel and S355J2 steel are both EN 10025-2, the difference is that they have different temperature requirements for impact energy: S355J0 - impact energy at 0 ℃ is required to be ≥ 27J. S355J2: impact energy at - 20 ℃ is required to be ≥ 27J.

Corten B steel strip,Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel, such as strength, toughness, ductility, forming, welding and cutting, abrasion, high temperature, fatigue and so on. The weathering resistance of weathering steel is 2-8 times of that of plain carbon steel, and the coating property is 1.5-10 times of that of plain carbon steel. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, etc..Corten B steel strip

When the stainless steel plate is alloyed with chromium, the type of surface oxide is changed to that formed on pure chromium metal. This tightly adherent chromium rich oxide protects the surface from further oxidation. This kind of oxide layer is very thin, through which we can see the natural luster of the steel surface, so that stainless steel has a unique surface.
