The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. A572 grade 42 high strength steel, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
A572 grade 42 high strength steel Flaw detection standard: our steel plates can be produced and inspected in accordance with China (JB4730, GB/T2970), the United States (A435, A577, A588), Japan (JIS G0801, JIS G0901), Germany (SEL072), Britain (BS5996), France (NFS04-305) and other domestic and foreign flaw detection standards. Delivery status: according to the user's requirements, A572 grade 42 high strength steel can be delivered in hot rolling, normalizing, tempering, normalizing and tempering, quenching and tempering, etc.
Based on the advantages of A572 grade 42 high strength steel steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel A572 grade 42 high strength steel products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
