02Core Advantages & Delivery Conditions
16Mo3 pressure vessel steel is supplied in standardized heat treatment states to guarantee stable mechanical performance under high-temperature and high-pressure working conditions.
Excellent Heat Resistance
Chromium and molybdenum alloying provides strong oxidation and scaling resistance for sustained elevated-temperature service.
Creep Resistance
Stable strength retention under long-term high-temperature load, suited to boiler and pressure-vessel components.
Stable Pressure-Bearing
Reliable load-bearing capacity and consistent properties for pressure equipment fabrication.
Good Weldability
Controlled carbon with balanced alloying gives favorable welding for fabricated structures and piping.
Delivery conditions: Normalized (N), Normalized & Tempered (N+T) and Quenched & Tempered (Q+T) are available. Specify the required condition and supplementary tests in your inquiry so we can quote and prepare the corresponding Mill Test Certificate.
03Equivalent Steel Grade
16Mo3 is equivalent to the Chinese chromium-molybdenum-vanadium grade 12Cr1MoV, a classic material for GB5310 high-temperature steel pipes and elevated-temperature service.
