Shipbuilding material JIS G 3114 grade SMA400BW tensile strength spot supply

Participating tenders with clients is part of our JIS G 3114 grade SMA400BW tensile strength business. Every year, we support a lot of clients to win tenders and supply steel materials to their govenment progects or state owned enterprise. Until now, we have built JIS G 3114 grade SMA400BW tensile strength long-term cooperation for many govermental departments of different countries such as Peru, Bangladesh, Indonesia, Egypt, Qatar, etc.. And we have built certain influence and credibility on the International market.

The alloy wear-resistant layer of JIS G 3114 grade SMA400BW tensile strength, wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is fibrous distribution, and the fiber direction is vertical to the surface. The alloy carbide has strong stability at high temperature, maintains high hardness, and has good oxidation resistance. It can be used normally within 500℃.
