SA573 Grade 70 raw material weldable carbon steel plate material heat treatment

Q355NHD is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and D represents quality grade (A, B, C, D, E) composition. SA573 Grade 70 raw material weldable carbon steel plate steel is an atmospheric corrosion-resistant steel plate with the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature and fatigue resistance.

Since it was established in 2000. Based on the domestic rich SA573 Grade 70 raw material weldable carbon steel plate product resources and the great steel demand of the international market, our SA573 Grade 70 raw material weldable carbon steel plate 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

The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products SA573 Grade 70 raw material weldable carbon steel plate. Today, the company will further expand its scale on the existing basis, with first-class products and better service, to make new friends from all over the world, hope that we will work together to create brilliant! Serve our customers with the concept of "being honest and operating with integrity"!

The wear-resistant composite plate, SA573 Grade 70 raw material weldable carbon steel plate should be pre heat treated to eliminate the residual stress produced in the machining process. If conditions permit, vacuum heating quenching and cryogenic treatment after quenching should be selected as far as possible. On the premise of ensuring the hardness of steel plate, pre cooling, step cooling and quenching or high temperature quenching should be selected as far as possible. For some wear-resistant composite plates, pre heat treatment, aging heat treatment and quenching, tempering and nitriding heat treatment can be used to control the accuracy of the wear-resistant composite plate.

The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, SA573 Grade 70 raw material weldable carbon steel plate deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
