Hss high speed steels still playing a very significant role in metal cutting.
High speed steel cutting tools.
18 tungsten 4 chromium 1 vanadium 0 7 carbon and the rest iron.
Hss tools have a harness of 62 64 rc.
Travers tool offers a wide range of high speed steel hss solid carbide cutting tools.
The ability to maintain the hardness required for cutting while at this temperature is a property known as red hardness or hot hardness and it is the primary defining characteristic of high speed steels.
It is often used in power saw blades and drill bits it is superior to the older high carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper hardness this property allows hss to cut faster than high carbon steel hence the name.
High speed steel is a high carbon tool steel containing a large dose of tungsten.
A typical hss composition is.
High speed cutting tools work well on all materials and can be coated to provide even better performance for particular materials.
Crucible steel was awarded a patent for the first recognized high speed steel in 1910.
