Abstract
The present invention relates to a precipitation hardening ferritic-pearlitic steel which is especially adapted for use with reciprocating valves in internal combustion engines. The steel according to the invention typically contains from 0.20 to 0.60%
carbon, 0.20 to 0.95% silicon, 0.50 to 1.80% manganese, 0.004 to 0.04% nitrogen and 0.05 to 0.20% vanadium and/or niobium. The balance of the steel is comprised of iron and incidental impurities.
carbon, 0.20 to 0.95% silicon, 0.50 to 1.80% manganese, 0.004 to 0.04% nitrogen and 0.05 to 0.20% vanadium and/or niobium. The balance of the steel is comprised of iron and incidental impurities.
