We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of A515 Gr 70 structural steel sheet boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with A515 Gr 70 structural steel sheet high-end steels and competitive price.

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, A515 Gr 70 structural steel sheet 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.

As the boiler steel plate A515 Gr 70 structural steel sheet is working under medium temperature (below 350 ℃) and high pressure, the boiler steel plate is not only subjected to high pressure, but also subjected to impact, fatigue load and water and gas corrosion. The performance requirements for boiler steel mainly include good welding and cold bending performance, certain high temperature strength, alkali corrosion resistance, oxidation resistance, etc.

A515 Gr 70 structural steel sheet, Hardened wear-resistant plates are gradually annealed at a temperature higher than 250℃ to lose their hardness, which greatly reduces the wear resistance. The welding process will also reduce the hardness near the weld; the wear layer of the bimetal wear plate is of high alloy composition, and there is a secondary hardening effect at a certain temperature, and it can generally work below 650℃.
