Sleipner Tool Steel 4.2 x 35 x 1000 mm

Uddeholm Sleipner steel is a highly alloyed chrome-molybdenum-vanadium tool steel characterized by its exceptional resistance to mechanical stress and wear. Its other excellent properties include high strength, resistance to chipping, dimensional stability during heat treatment, good machinability, grindability and hardenability. It has excellent cutting properties, thanks to the chromium content of 7.8% it also shows good resistance to corrosion. It is an extremely versatile tool steel, used primarily in the knife industry for the production of quality combat attack knives, hunting knives, outdoor knives, or rescue knives. In East and Southeast Asian countries where ASSAB distributes, Uddeholm Sleipner steel is called Assab 88. More material information: Sleipner EN, Assab 88 EN, Uddeholm premium steel EN.

Heat treatment of Sleipner tool steel

Soft Annealing: 850 °C
Hardening: austenitizing temperature: 950 – 1080 °C (usually 1030 – 1050 °C), heating time 30 minutes
Annealing: the lowest annealing temperature is 180 °C, the minimum annealing time is 2 hours
Achieved hardness: 60 - 62 HRC

Chemical composition and other markings

Chemical composition: C 0.9; Si 0.9; Mn 0.5; Cr 7.8; Mo 2.5; In 5.0
Other designation: Assab 88

Supplied material

The material is delivered in an annealed state.
There may be scale or surface corrosion on the surface.
Some material may already be descaled by sandblasting.
According to the production technology, the material may not be perfectly straight.
Microcracks may occur on the surface of the material from production, so it is recommended to sand off approx. 0.1 - 0.15 mm from the top layer.
The material is split with 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 blade steel

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

Grinding and sharpening knife steel 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.
