INTRODUCTION OF HSS

In today’s World - for modern industrial production, particularly on mechanical & CNC mass production, tooling is one of the key factors pertaining for the performance of shaping and forming processes. Almost all tools employed for this purpose are made from high speed steels. The use of high speed steels has also gained increasing importance for chipless shaping, eg. for extrusion, blanking and punching tools.

HSS chemical composition distinctly differentiates between W-, Mo- and W-Mo alloyed steel grades, which contain different amounts of carbon, vanadium and cobalt elements to strengthen its own occurrence.

Characteristic properties HSS GRADES

 working hardness
 High wear resistance
 High retention of hardness and red hardness
 Excellent toughness
 
ALLOYING ELEMENTS PRESENT IN HSS PROPERTIES
 
Carbon : forms carbides, increases wear resistance, is responsible for the basic matrix hardness.
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: improves red hardness and retention of hardness of the matrix.
 
HIGH SPEED STEEL CHEMICAL COMPOSITION
 
 
 
HIGH SPEED STEELS - EQUAVALENT GRADES
 
 
 
STEEL PROPERTIES
Standard grade for High Speed Steels; owing to its balanced composition has good toughness and cutting performance, hence many applications.
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.
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
 

APPLICATIONS

High performance Gear Cutting Hobs, Shapers, Milling cutters, Bevel tools, of all kinds of highly stressed twist bits and taps, shaped shear blades, for working high strength materials, broaches. Cutting tools for roughing or finishing, such as: helical bits, milling cutters of all types, taps, dies, spindles, reamers, thread rolling tools, drill bits, circular saw segments. Impact tools and those used for working wood. Cold forming tools such as dies and punches for cold extrusion and cutting and fine cutting tools.
