Wear resistant reinforced Stellite

Stellite 190 is a cobalt alloy with excellent wear resistance, high temperature strength, and corrosion resistance. Mainly used in oil and gas industry applications, especially demanding applications in high temperature and wear resistant areas.

​Differences from Stellite 6K
*Differences in original professional usage are omitted.
Due to its high abrasion resistance, Stellite 6K has a wear resistance that exceeds that of steel depending on the object to be cut, even if its hardness is low. Stellite 190 has a major drawback of quickly losing its sharpness, but this is not the case.

The major difference between Stellite 6K and the conventional Stellite 6K used in knife applications is its hardness. While Stellite 6K has 48 HRC±, Stellite 190 has a very high carbon content of 58 HRC± (maximum 60 HRC), and has the highest carbon content among the many Stellite types, so it is no different from ordinary knife steel. This will be the hardness. This combined with Stellite's unique low coefficient of friction gives it extremely strong wear resistance.

​Wear resistance
I previously did a comparison of the wear resistance of Stellite 6K and D2 on Youtube. The object to be cut was straw, and the result was that Stellite 6K had a value more than four times that of D2. This indicates that Stellite itself has excellent wear resistance.

​Toughness
The toughness value of Stellite is not very high compared to knife steel. This is due to the roughness of the substructure. Although it cannot be said to be good for unusual loads such as putting your full weight on a tree, it can be used without problems for applications such as bushcraft.
​
Sharpness
In terms of sharpness, the subdivision of Stellite itself is larger than that of modern knife steels, so it cannot produce the finely honed, ultimate sharpness of a carbon steel knife. However, it is possible to have a knife-like blade that is said to be extremely sharp, capable of smoothly cutting through thin paper.

​Corrosion resistance
Due to the increased carbon content, corrosion resistance is a concern, but in terms of chemical applications, it is lower than Stellite 6K, but it is only for chemical use, and as before, it will rust even in environments such as seawater or the Dead Sea. It is not.

​Heat treatment
Another feature is that it is a metal that does not require hardening and is designed for use in high-temperature environments, so the blade will not dull even at high temperatures of over 900℃.

Needless to say, the processing difficulty is even harder than Stellite 6K, which is already hard.

Stellite 190 has a very special purpose and is only produced in round bars, so it has never been used in knives until now, but ISZ KNIVES has a partner steel manufacturer specially produce plates for it. I'm here.

This is the Stellite 190, a high-performance blade that does not rust and cuts whatever you cut for a long time.
