◆0Cr17Ni7Al is a precipitation-hardening steel with Al added, used as springs, washers, calculator components, etc.
◆0Cr15Ni7Mo2Al is used for high-strength containers, parts and structural parts with certain corrosion resistance requirements.
◆The performance of 0Cr15Ni5Cu4Nb is similar to that of 0Cr17Ni4Cu4Nb, but it has better lateral performance.
◆0Cr12Mn5Ni4Mo3Al (Gangyan 69111) has better plasticity than 0Cr15Ni7Mo2Al.
◆0Cr17Ni4Cu4Nb Precipitation hardening steel with Cu added, widely used in shafts, high-strength structural parts requiring corrosion resistance for steam turbine parts.
◆XM－25 is heat and high temperature resistant, suitable for petroleum, chemical, aerospace, nuclear power and other industries.
