Since it was established in 2000. Based on the domestic rich P265GH steel product resources and the great steel demand of the international market, our p265gh steel service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

Our company supply the cold rolled steel coil for customers, and the cold rolled steel coil we produce the standard of JIS, EN, DIN. The available grades include the JIS G 3141 SPCC, SPCD, SPCE, p265gh steel and so on. The EN 10111 standard include DD11, DD12, DD13, DD14. The EN 10130 standard include DC01, DC03, DC04 etc. The standard of DIN 1623 available grades have ST12, US113, RRST13 and ST14.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. p265gh steel, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the p265gh steel quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After p265gh steel quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

42CrMo alloy steel p265gh steel: low temperature tempering welding performance thermal processingThe heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.

Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our p265gh steel service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's p265gh steel customer service to establish a good, comprehensive, full service system.
