Product Detail

Shanghai Metal Corporation is a professional manufacturer and supplier of Tough and low temperature alloy plate with high quality and reasonable price.

This kind of tough alloy steel has good toughness and high strength at extremely low temperatures. Compared with austenitic stainless steel and aluminum alloys, it has a smaller coefficient of thermal expansion and is more economical. The highest grade 9Ni of these materials, its service temperature can reach as low as -196℃. Since 1960, studies have proven that it can be used safely after welded without stress relief heat treatment, 9Ni steel has become one of the main materials used to manufacture large LNG storage tanks. The main characteristics of steel are high nickel content, high purity, high strength, high low temperature impact toughness, and good welding properties.

If you want to know more about our tough and low temperature alloy plate, please feel free to contact us, we will reply you within 24 hours.
