Weathering steel is mainly used in railway, vehicles, bridges, towers and other steel structures exposed to the atmosphere for a long time. sa709gr50 asme bridge steel. Weathering steel is used to make structural parts such as containers, railway vehicles, oil derricks, seaport construction, oil production platform and containers containing hydrogen sulfide corrosion medium in chemical petroleum equipment. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, which benefits the weathering steel component manufacturers and users.
Chromium element (Cr element) can improve the strength and hardness of sa709gr50 asme bridge steel, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to sa709gr50 asme bridge steel full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our sa709gr50 asme bridge steel steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
