Description
This is a high carbon martensitic stainless steel with moderate corrosion resistance good strength
and the ability to obtain and keep excellent hardness (Rc 56) and wear resistance.
Applications
Ball bearings and races, gage blocks, molds and dies, cutlery, valve components, knives and measuring instruments.
All kinds of cutting tools - surgical instruments, pressing dies for synthetic resin.

Soft Annealing
Heat to 730-780oC, cool slowly.
Hardening
Harden from a temperature of 980-1030oC followed by oil or air quenching.
Forging
Hot forming temperature: 1100-800oC.
Machinability
Best machined in the annealed condition. Tough, stringy chips can be best handled by the use of chip breakers.
Carbide or ceramic tooling is recommended.
Corrosion Resistance
Resistant to a wide variety of media including fresh water, steam, petroleum products and alcohol.
Welding
This steel is not commonly welded due to its tendency to air harden.
If it must be welded, preheat to 260oC and post weld treat at 732-760oC for 6 hours followed by a slow furnace cooling to avoid cracking.
Cold working
This alloy is considered only slightly cold workable by common practices.
