2, Application

High strength steel in grade HG785D /HG785E has been widely used in construction machinery. It has been incorporated into its main raw materials. Because of its excellent quality, its product exhibit good mechanical properties in the earthquake relief and rescue. With the continuing escalation of mechanical products, the wisco production of high strength steel has been widely used in the modified car industry, coal mining machinery, engineering machinery, fan industry, electrical equipment, trucks, mining trucks and other steel products, a broad market prospect delivery and use of high-strength steel provides a basis for the development.

We Wuhan Stech is committed to serving the majority of high-strength steel users
To deepen its relations of cooperation with Wuhan Iron and Steel, on behalf of clients set rolling futures premium, short delivery time. Responsible for the whole steel mills expediting, delivery, transportation, shipping and other sectors,We guarantee to provide customers with comprehensive service.
