16Mo3 vs Ck60 / C60E: 57% composition overlap. Moderate differences, generally not direct substitutes.
16Mo3 vs Ck60 / C60E
Side-by-side chemical composition and mechanical property comparison.
Overview
16Mo3
1.5415
Molybdenum-alloyed pressure vessel steel — THE European Mo-Kesselblech. Mo 0.25-0.35% improves creep resistance and elevated-temperature strength to ~500°C (higher than P265GH at ~400°C). Used for superheater tubes, boiler drums, steam piping, and heat exchangers in power generation. EN 10028-2 + PED.
Ck60 / C60E
1.1221
Plain carbon quenched & tempered steel — 0.57-0.65% C. Highest practical C for Q&T without excessive brittleness. Good surface hardness (HRC 55-60) with adequate core toughness. Modern designation C60E (EN 10083-2), traditional Ck60 still widely used. Used for crankshafts, connecting rods, rail wheels, axles, and machine tool spindles where alloy cost is not justified.
