Technical properties Technical properties
CrNiMo alloyed heat-treatable steel (tempered condition) for components with high strength and toughness. It is used for through-hardening components in automotive and mechanical Engineering. The material is usually difficult to weld. Components are usually used in the quenched and tempered state. An optionally achievable surface hardness through nitriding: approx. 60-64HRC.
   
Applications Applications
The Corrosion Resistant Steel BS 823 M 30 is suitable for the following applications: Shafts, gear parts, gears, bevel gears, driving pinion.
   

The Heat-Treatable Steel BS 823 M 30 is available as Round steel.
