15 Mo 3 material, 15 Mo 3 supplier,stock

15 Mo 3 material use, 15 Mo 3 material used for low and medium pressure boiler (working pressure not higher than 5.88Mpa, working temperature below 450 ℃ ) of heating surface tubes; for high-pressure boilers (above 9.8Mpa working pressure in general, working temperature between 450 ℃ ~ 650 ℃ ) of heating surface tubes, economizer, superheater, reheater 15Mo3.

15 Mo 3 material is DIN17175 standard steel pipe, boiler and Superheater carbon molybdenum steel small diameter tubes, pearlitic heat resistant steel. Its chemical composition is simple, but contains molybdenum, so maintaining the same process performance and carbon case, the heat strength properties than steel. 15 Mo 3 material performance is good, cheap and widely adopted countries in the world. But 15 Mo 3 material long-term operation at high temperature graphite tendency, so 15 Mo 3 material temperature should be controlled below 510 ℃ , the smelting should limit the amount of Al added to control and slow down the process of graphitization.
