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

Applications:
Heavy duty milling cutters, broaches, reamers, cutting tools, shaper cutters & rotary shave cutters for machining hard materials, socket head & hole punching dies for producing nuts & tap drills. Die blocks, broaching tools, cold extrusion rams, tools subject to extensive mechanical stresses. Heavy roughing work, machining high tensile steels, difficult to machine cast steel, grey cast iron, chill castings NF metals & non-metal material. Turning, planning & shaping tool, rough milling cutters. End mills, hobs, shaper cutters, cold forming tools, stamping & punching tools, cutting tools, working rolls for cluster rolling stand.
