DISTRIBUTORS, IMPORTERS & STOCKISTS OF ALL GRADES OF HIGH SPEED STEEL
HSS M42 is 8% Cobalt mix molybdenum high speed tool steel which has rich high red hardness and very excellent cutting abilities as a tool steel as compare to HSS M35 due to its ability of having 8% Cobalt. HSS M42 is finest effective High-carbon; high-speed steel grade based on Mo, with high resistance to wear, red hardness and toughness. This steel grade displays good grind ability as a result of its low V content. Tools severe mechanical wear, e.g. in cases of small cross-section cuts and high cutting speeds.
It has components such as Molybdenum (Mo), Tungsten (W) & Cobalt (Co), Vanadium (V)
grades, possessing high hardness, excellent cutting properties, red hardness making
it as one of the best fine grade tool steel to generate hardness upto 64-66 HRC post
heat treatment.
This conventional steel has mix of cobalt & Moly elements and carbides in it
are small and evenly distributed. It has high Tensile strength & 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
