The A573 gr 58 BV certificate plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The A573 gr 58 BV certificate products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.
40Cr alloy belongs to gb3077 "alloy structural steel". The carbon content of 40Cr steel is 0.37% ~ 0.44%, which is slightly lower than that of 45 steel. The content of Si and Mn is equivalent, and the content of Cr is 0.80% ~ 1.10%. In the case of hot rolling supply, the 1% Cr basically does not work, and their mechanical properties are roughly the same. Because the price of A573 gr 58 BV certificate is about half of that of 45 steel, 40Cr is not needed for the purpose of economy.
40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel A573 gr 58 BV certificate is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.
Molybdenum is a well known alloy element. Molybdenum can refine the grains of steel material, improve the hardenability and thermal strength, and maintain sufficient strength and creep resistance at high temperature. Adding molybdenum to A573 gr 58 BV certificate, structural steel can improve mechanical properties. Molybdenum can also restrain the brittleness of alloy steel caused by quenching treatment.
