DISTRIBUTORS, IMPORTERS & STOCKISTS OF ALL GRADES OF POWDER HIGH SPEED STEEL
ASP 4 produced by powder metallurgy with an homogeneous structure and a good toughness. Its wear resistance is good. Uniform and high dimensional stability after heat treatment
PM4 Steel - (Powder HSS M4) also known as ASP4 is a high Vanadium-chromium- molybdenum-tungsten alloyed Powder based HSS steel Suitable where adhesive wear & chipping are the dominant problems occur such as SS, Mild steel, copper, aluminum or thicker work material
Powder made steel formation process results in a homogeneous microstructure with a finer, more uniform carbide distribution imparting superior dimensional stability, grind ability and toughness when compared to steels produced by conventional processes
