IS 2062 E450 BR plates which have the quality of good tensile strength, excellent thickness, good elongation, good yield strength. We provide high-end finished products which have accurate dimensions, good durability i.e complete customer satisfaction. Our p355gh material standard plates have different applications in a number of industries such as paper, chemical, natural gas, cement industries, oils, shipbuilding etc.

It has good toughness. By strictly controlling the chemical composition, reducing the content of p355gh material standard harmful elements and selecting reasonable heat treatment conditions, NM360 steel plate has good toughness. Therefore, the highly reliable structural parts can be constructed according to the brittle failure of wear-resistant components. Uniform and beautiful quality, p355gh material standard using advanced technology and equipment, combined with high and scientific technical management, the material and shape of the product are even and consistent.

Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The p355gh material standard cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.

20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, p355gh material standard. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.
