What is the 16Mo3 steel chemical composition?

16Mo3 is a steel plate for pressure vessels under EN10028-2 standard. This specification specified grades of 16Mo3 chromium-molybdenum steel alloys are used at elevated operating temperature materials are used as weldable steel in industrial boilers and stainless steel pressure vessels in the oil, gas and chemical industries.

16Mo3 steel chemical composition (%)
C: 0.12~0.2 Si: ≤0.35 Mn: 0.4~0.9 P: ≤0.025 S: ≤0.01 Cu: ≤0.3 Ni: ≤0.3 Cr: ≤0.3 Mo: 0.25~0.35 Al: ≥0.02 N: ≤0.012

Production process: use electric furnace + refining outside the furnace + vacuum degassing method to exercise, fine grain calm steel
