DISTRIBUTORS, IMPORTERS & STOCKISTS OF ALL GRADES OF HIGH SPEED STEEL
HSS M2 is a molybdenum based standard high speed tool steel which is commonly used worldwide for generation of cutting tools such as drills, reamers, gear cutters, broaches, die steel. It has components such as Molybdenum (Mo), Tungsten (W) & Cobalt (Co), Vanadium (V) grades, chrome making it as fine grade tool steel to generate hardness upto 60-62 HRC post heat treatment. The carbides in it are small and evenly distributed. It has high wear resistance. This grade is most effective and economically priced making it most commonly used high speed steel grade.

Elements in HSS properties
Standard grade for High Speed Steels; owing to its balanced composition has good toughness and cutting performance, hence many applications
- Carbon : : forms carbides, increases wear resistance, is responsible for the basic matrix hardness. High Speed Steel with high molybdenum and carbon. It has high wear resistance, high red hardness and good toughness. With its low vanadium content, this grade has very good grind ability.
- Tungsten and molybdenum: improve red hardness, retention of hardness and high temperature strength of the matrix, form special carbides of great hardness.
- Vanadium: forms special carbides of supreme hardness, increases high temperature wear resistance, retention of hardness and high temperature strength of the matrix.
- Chromium: promotes depth hardening, produces readily soluble carbides.
- Cobalt: HSS containing cobalt content is a high performance steel with good cutting capability & ensures high red hardness and tempering retention. It is particularly suitable in thermal stress situations and for intermittent cutting
Characteristic properties HSS grades:-
- High working hardness
- High wear resistance
- High retention of hardness and red hardness
- Excellent toughness
