Most of the P355GH steel size steel materials used in industrial boilers are carbon steel materials. In a narrow sense, the boiler steel refers to the special steel used for manufacturing industrial boilers and power station boilers, mainly including pressure vessel steel, anti-oxidation steel and hot strength steel. Some of them are carbon steel, most of them are medium and low alloy steel, and a few are high alloy steel p355gh steel size. In a broad sense, the boiler steel includes all the steel used to manufacture industrial boilers and utility boilers.

The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. p355gh steel size, 20CrMo steel pipe is generally used in quenching and tempering state.

The correct choice of billet type, section shape, size and weight are of great significance to p355gh steel size steel rolling production.
