发明名称 Steel Alloy
摘要 An alloy, such as a tool steel containing, in percent by weight, 0.5%-0.7% carbon; 1.80%-2.50% chromium; 0.90%-1.20% molybdenum; 3.50%-5.50% nickel and 0.60%-1.50% vanadium. The steel alloyed accordingly is eminently suitable for heat treatments for influencing strength. With a carbon content of less than 0.7%, a partially martensitic metal structure having a high ductility can be formed by way of hardening processes. Due to surface hardening, the carbon content may in some portions on the outer surface be greater than 0.7%.
