ASTM A335 P11 Seamless Ferritic Alloy Steel For High Temperature Service
Chromium and molybdenum are important elements of P11. Chromium， or chrome， improves high-temperature strength， increases oxidation resistance and raises the tensile， yield and hardness at room temperatures. Molybdenum increases the strength， elastic limit， resistance to wear， impact qualities and hardenability. It increases the resistance to softening， restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is also the most effective additive for increasing high temperature creep strength， or creep resistance. It also enhances the corrosion resistance of steel and inhibits pitting.
