Ship construction use A131 DH36 structural steel,Our 12Cr2Mo1VR steel plate breaks through the specification limit, with a thickness of up to 180 mm and a single weight of 43.7 tons. The flaw detection can meet the highest level of NB / T47013 flaw detection level. Its thickness and unit weight exceed the production limit of vanadium steel. The 12Cr2Mo1VR steel plate with such specifications has high technical requirements, severe performance requirements, and great production difficulties. In the production process, it is easy to appear the tail area defects, which will cause the steel plate to fail inspection. So please choose your suppliers carefully.ship construction use A131 DH36 structural steel

Ship construction use A131 DH36 structural steel,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. 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%.
Modern steel-making steel purification facilities and advanced quality control methods have been perfected. Rolling steel can be produced according to controlled rolling and controlled cooling, normalizing, and quenching and tempering processes to produce σs 390-685Mpa series products. Low alloy high strength structural steel plate has stable quality, good wear resistance and low temperature toughness. It can be widely used in the manufacture of mining machinery, engineering machinery, high-rise buildings and heavy vehicles.
