ASP® : HIGH SPEED STEEL BY POWDER METALLURGY |
|
|
Erasteel has produced powder-metallurgy High Speed Steels since 1969. These grades are marketed under the ASP® brand name, of a worldwide fame.
Thanks to the powder-metallurgy process, higher-quality products can be obtained, offering the following advantages :
 a higher hardness, due to a higher content of carbide-forming elements
a higher toughness, because the material is free from carbide segregation. In addition, the ESH process removes about 90% of non-metallic inclusions, ensuring better reliability of powder-metallurgy HSS tools
|
|
isotropic properties, because the material exposes a structure with an even distribution of carbide particles in the matrix phase, in contrast to ingot cast high speed steels where carbides tend to form lines during transformation

Thanks to these properties, ASP® grades are widely used in many applications: cutting tools (hobs, broaches, drills, endmills, taps, etc.), saws, knives, cold- & hot-work tooling and wear parts.
