SPMR8
Improved P/M high-speed steel with toughness and corrosion resistance.
SPMR8 contributes to extended service life of dies and tools.
-
High performance
-
Cost down
Features
Making the most of alloy design, which the powder metallurgy process enables, and homogeneous and dense metallographic structure, outstanding toughness and corrosion resistance are achieved.
- Toughness is greater than that of powder high-speed steel (SPM23).
- Corrosion resistance is equivalent to or higher than that of high-chromium cold-work tool steel.
- Hardness and wear resistance are equivalent to powder high-speed steel (SPM23).
Merit
SPMR8 improves dies and tool service life and contributes to cost reduction.
- SPMR8 provides high hardness and high toughness and contributes to suppress early cracking and chipping while dies are used.
- The outstanding corrosion resistance to various acid environments contributes to suppression of early wear arising from corrosion of plastic molding machine components.
Application
- Cold forging dies and cold-work tools where high toughness is essential.
