ČSN 14 220 / 1.7131 / 16MnCr5


Stainless structural manganese-chromium steel for cementation. Steel is well-workable during hot work, after soft-annealing and also cold work, it is well-machinable and weldable.


Suitable for machine components for heat treatment up to diameter 35 mm, for cementation with a high hardness in the core, e.g. shafts, cogwheels, camshafts, valves lifters, piston pins and jaw clutches.

Tool steel meets the requirements of various kinds of tools, e.g. for machining, hot- and cold-working, measuring instruments and die-casting moulds. We also offer high-speed steel.

Special tool steel is suitable for the manufacture of moulds, dies and pressing tools. This steel have better end-use properties than common classic steel, therefore it can help saving considerable amounts of money in manufacture.

This patented Swedish steel is distinguished by its high range of use. It is suitable for the manufacture of tools and moulds as well as machinery parts. This material can replace many kinds of classic tool and structural steel.
