Grade Description
Coated HSS-E-PM, PVD heat- and wear-resistant high-vanadium, high-cobalt
powder metal HSS-E-PM substrate. Coating consists of low-friction CrC/C
over wear-resistant TiN base layer. Use for tapping titanium and titanium alloys.
S
Surface-treated HSS-E-PM: powder metal HSS-E-PM substrate with nitride surface
treatment that provides wear resistance in non-ferrous materials including titanium.
Limited use. Use for tapping titanium and titanium alloys.
S
Coated HSS-E-PM, PVD heat- and wear-resistant high-vanadium cobalt
powder metal HSS substrate coated with wear-resistant TiCN base layer.
S
Surface-treated HSS-E-PM powder metal HSS-E substrate with oxide/nitride
surface treatment that provides wear resistance in nickel alloys.
