Steel 54SiCr6 - 8 x 30 x 670 mm

Steel 54SiCr6, 8 x 30 x 670 mm

Special structural steel for the production of springs and other extremely stressed mechanical parts. The thermally and mechanically processed material has high strength, flexibility, hardness and toughness. Due to its properties, it is also suitable for the production of knives, machetes and, above all, long sword blades.
Recommended values ​​for hardening knives are 52 - 58 HRC, long blades 50 - 54 HRC.

Supplied material

The material is delivered in annealed condition.
There may be scale or surface corrosion on the surface.
Some material may be descaled by sandblasting at the factory.
Depending on the production technology, the material may not be perfectly flat.
Microcracks may be present on the surface of the material during production, therefore it is recommended to grind from the top layer approx. 0.1 - 0.15 mm.
The material is divided by a water jet, laser technology or a band saw.
In the case of laser cutting of the material, the edge may be turbid after cutting, so when subsequently cutting the material with a band saw, use a weak edge structure to grind it so as not to dull the saw band.
We will send the chemical composition of the specific purchased steel, upon request.

Dimensional tolerances

Material thickness tolerance: +/- 0.28 mm
Material width tolerance: +/- 1.0 mm
Material length tolerance: +/- 3.0 mm

Another steel for the blades

You can find other steel for the blades in the category Knife steel.

Grinding and sharpening of cutlery and blades

Standard sanding belts with ceramic grain can be used for grinding steel, eg 3M 777F, Norton R976, VSM XK870X, Deerfos PS999, or sanding belts with premium ceramic grain, eg 3M Cubitron II 984F, 3M Cubitron II 784F, Norton R980, Deerfos Bora7. Sanding belts 3M Trizact 237AA, 3M Trizact 337DC, Norton NORaX U254, VSM KK712X, VSM KK772J and others can be used for sharpening and polishing blades.
