18Cr11NiMoNbVN 42Cr9Si2 45Cr9Si3 Martensitic Heat Resistant Steel Bar, Multi-Alloy For Heavy Gas Turbine Blades & Engine Intake/Exhaust Valves
Product Spotlights
Temperable martensitic valve & turbine steels maintain stable mechanical performance under cyclic high-temperature flue gas environment. S47450 Nb-V-N refined ESR steel delivers outstanding thermal fatigue resistance for large power gas turbine heavy blades. S48040 42Cr9Si2 silicon-chrome alloy balances cost & oxidation resistance under 800℃ for light-duty engine intake valves. S48045 high-silicon 45Cr9Si3 resists severe gas abrasion up to 850℃ for heavy truck exhaust valves. Low thermal expansi
