High Speed Steels

- 19
- Elements tabulated
- 11
Overview
Tungsten- and molybdenum-base high speed steels that retain hardness at cutting temperature, including the M and T series.
IMS handles high speed steels as both prime material and as arisings recovered from industrial processing. Material is sorted and segregated by grade, so it returns to the melt as a known specification rather than a mixed stream.
Properties
- Wear Resistant
- High Hardness at Temperature
Applications
- Cutting of Metals (High Cutting Rates)
