15Mo3 reads: fifteen molybdenum three. Belongs to the high temperature resistant alloy steel plate, commonly used in medium and high temperature environment in the pressure vessel manufacturing. Such as steam boiler, coal economiser, superheater, petrochemical industry, pro-hydrogen equipment, etc. 15Mo3 steel plate is generally delivered in normalised or normalised and tempered condition. Maoyang Iron and Steel can produce 15Mo3 steel plate 8--150mm thickness, and can undertake small batch rolling.
15Mo3 steel plate chemical composition:
C carbon : 0.12-0.2 Mo molybdenum : 0.35 Mn manganese : 0.4-0.8
P Phosphorus : 0.030 Sulphur : 0.030 Ni Nickel : 0.25-0.35
15Mo3 steel plate tensile yield strength:
Yield strength: ≥270MPa
Elongation: ≥22%
Shrinkage rate: ≥38%
Impact toughness value: 34J
15Mo3 steel plate is melted by oxygen top blowing converter method, flat furnace method or in electric furnace.
