Overview
10CrMo9-10
1.7380
Low-carbon Cr-Mo steel for elevated temperature pressure equipment. Excellent creep resistance up to 530°C. The standard grade for boiler tubes, headers, and pressure vessels in power generation and petrochemical industries.
16MnCrS5
1.7139
Free-cutting variant of 16MnCr5 (1.7131) — sulfur addition (0.020-0.040%) for improved machinability on CNC automatics. Same case-hardening properties: surface 60-62 HRC after carburizing. THE high-volume automotive gear steel where machining cost matters. Used for transmission gears, shafts, pinions, and other carburized parts produced on CNC lathes and multi-spindle automatics.
