EN 10088‑1 Certified X12CrS13 Quenched & Tempered Steel – Superior Machinability

Material X12CrS13 is comparable to X 12 CrS 13 acc. to Key to Steel 1995 resp. steel-iron-list 1994. This material is a martensitic free cutting steel showing favorable machinability but lower ductility and corrosion resistance than the usual 13 per cent Cr-steels. Application for all kinds of turning workpieces, such as screws, nuts, bolts as well as for construction parts in water and steam. Welding is not common. No forming is designated.
