DISTRIBUTORS, IMPORTERS & STOCKISTS OF ALL GRADES OF HIGH SPEED STEEL
HSS T42 is 9%Tungsten based high speed tool steel with 10% Cobalt, 3.15% Vanadium & 3.5% moly. HSS T42 is totally different material than T4 or T5, T42 has all the elements of Moly, chrome, vanadium , cobalt and tungsten which makes it properties balanced to cut all cutting parameters which have high hardness and strength.
Suitable to cut all types of alloy steel, it has High Toughness and good cutting properties.
Cutting parameters which has high tensile strength, Tungsten in this tool steel makes it easy to cut them - hardness upto 64-67 HRC post heat treatment.
Outstanding Features
- High toughness
- High wear resistance
- Stabilized heat treatment property
- Stable performance due to uniform and fine carbide distribution
- Good mechanical properties coming from fine and uniform grain size
- High purity with least inclusions and gases

Elements in HSS properties:
Standard grade for High Speed Steels; owing to its balanced composition has good toughness and cutting performance.
- 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
- 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.
APPLICATIONS
