16Mo3 vs 9SMnPb28: 13% composition overlap. Significantly different materials serving different application areas.
16Mo3 vs 9SMnPb28
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.
9SMnPb28
1.0718
Leaded free-cutting steel — Pb (0.15-0.35%) + S (0.24-0.33%) for maximum machinability. THE ultimate Automatenstahl: machinability rating ~175% (vs 100% for 11SMn30). Pb acts as chip-breaker and tool lubricant. Used for high-speed automatic screw machine production of screws, nuts, fittings, bushings, and any part where surface finish and cycle time matter most. NOTE: Pb content being phased out under EU ELV/RoHS — replacement grades emerging.
