40Cr10Si2Mo 80Cr20Si2Ni Martensitic Heat Resistant Steel Bar, Cr-Si-Mo & High Cr-Ni Alloy For Truck & Aero Engine Intake Exhaust Valves
Product Spotlights
Temperable martensitic valve steels feature silicon-based anti-oxidation film for long-cycle high-temperature flue gas service. S48140 Cr-Si-Mo alloy boosts creep resistance below 650℃ to resist diesel exhaust sulfidation for medium-duty truck engine valves. S48380 high 20Cr-Ni-Si grade withstands oxidation up to 900℃ with outstanding toughness for heavy marine & aero engine exhaust valves. Adjustable hardness via quenching & tempering, stable hot forging performance. Custom dimensional cutting
