Abstract (en)
[origin: EP0411282A2] The invention relates to the use of precipitation-hardenable ferritic-perlitic steels, consisting of 0.20 to 0.60% of carbon 0.20 to 0.95% of silicon 0.50 to 1.80% of manganese 0.004 to 0.04% of nitrogen and 0.05 to 0.20% of vanadium and/or niobium, the remainder being iron and impurities from the smelting process, as a material for gas reversing valves of combustion engines.
