series
High strength stainless steel for construction machinery refers to the stainless steel used in mining, bridge construction and all kinds of engineering construction, which requires the material to have high yield strength, fatigue strength, wear resistance and good corrosion resistance. Our high strength stainless steel for construction machinery includes duplex threaded stainless steel for ocean engineering and high nitrogen stainless steel for mine screen mesh.
Main product Features
●Product quality: High nitrogen stainless steel has no magnetic, good wear resistance, tensile strength ≥100oMPa, is more than 1.5 times of conventional austenitic stainless steel; Bridges with duplex threaded stainless steel designs can last up to 120 years, twice as long as normal Bridges.
●Market development: The monthly sales volume is about 300 tons.
●Application: Due to its high strength and corrosion resistance, it is mainly used in various construction, Bridges, mines and other fields.
