DIN 1.2355/50CrMoV13-15 AISI ASTM S7/T41907 Hot work Tool Steel
1: AISI S7 steel introduction
AISI S7 tool steel is a shock-resistant air hardening steel. AISI S7 steel has exceptional impact properties plus the highest hardenability of shock resisting grades of tool steel. Steel S7 also possesses good softening resistance at high temperatures which gives it hot work capabilities. Since S7 steel hardens in air, it is also safe and stable in heat treatment.
AISI S7 tools steel has an unusual combination of properties, making it suitable for an extremely wide range of tool and die work - where shock-resistance, medium hot-work properties, or ease of machining and heat-treatment are most important.
