Applications

  (1)  Application :

          HSS Square tool bits ,Broch ,Precision knives ,etc.

   (2)  Alloy elements present in HSS properities :

     ♦ Carbon:forms carbides ,increases wear resistance ,is responsible for the basic matrixhardness. 

     ♦ 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 ,increase high temperature wear                     resistence ,retention of hardness and high temperature strength of the matrix .

     ♦   Chromium :promotes depth hardening ,produces readily soluble carbides .

     ♦   Cobalt :imoroves red hardness and retention of hardness of the matrix
