17MN4 steel plate, p355gh plate, DIN 17135 17MN4 steel plate is a kind of material for boiler and pressure vessel steel. DIN 17135 17MN4 steel plate is characterized by a minimum yield strength of 220 - 295 MPa and by good weldability, so 17MN4 steel is mainly used for manufacturing boilers, pressure vessels and pipes transporting hot liquids.

12Cr1MoVR steel plate is suitable for medium and high temperature pressure vessels, and implements GB713-2014 standard. 12Cr1MoVR pressure vessel plate is usually delivered in normalizing + tempering state. According to the special agreement at the time of order, 12Cr1MoVR steel plate can also be delivered in annealing or tempering state, which significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.

Quenching Improve the hardness of p355gh plate steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of p355gh plate steel and comprehensive mechanical properties.

According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. p355gh plate, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.

Both parties shall confirm the p355gh plate material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the p355gh plate steel plant.
