JIS SUH3
Ordinary heat-resistance alloy (martensitic) which has magnetism and is widely applied to intake valve for internal combustion engine.
JIS SUH36 (21-4N)
high qualty heat-resistance alloy belonging to austemtic steel (non-magnetic) that is excellent in wear and corrosion resistance under high temperature and applicable to exhaust valve for heavy duty engine use.
STELLITE
cobalt-bast alloy to be welded on valve face (exhaust valve for heavy duty engine) for the purpose of specially improving wear and corrosion resistance under high temperature.
