The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, ZQS700L automobile structure steel plate seamless steel pipes for ships and petroleum cracking ZQS700L automobile structure steel plate steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many ZQS700L automobile structure steel plate products have been exported to the Middle East, India, Southeast Asia and Europe and America.

The company can provide the dimensions, shape, weight, technical requirements, test methods, inspection rules, packaging, markings and quality certificates of high-quality carbon structural steel hot-rolled steel plates and strips. Carbon and alloy steel grades 15Cr, 20Cr, ZQS700L automobile structure steel plate, 30Cr, 35Cr, 40Cr, 45Cr, 50Cr, 38CrSi, 12CrMo, 15CrMo, 20CrMo, 25CrMo, 30CrMo, 35CrMo, 42CrMo, 50CrMo, 12CrMoV, 35CrMoV, 12Cr1MoV, 25Cr2Mo1V, 38CrMoA1, 40CrV, 50CrV , 15CrMn, 20CrMn.

High wear resistance: fully automatic CNC stacking equipment, independent of manual ZQS700L automobile structure steel plate welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the ZQS700L automobile structure steel plate hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite ZQS700L automobile structure steel plate wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the ZQS700L automobile structure steel plate 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 ZQS700L automobile structure steel plate quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
