5CrNiMo SKT4 1.2713 L6 Hot Forged Rolled Annealed Tool Steel
1: L6 steel introduction
L6 steel grade is in L-type for special purpose tool steels. AISI L6 tool steel is in the general class of alloy, oil-hardening tool steel that is characterized by good toughness. ASTM L6 tool steel is suitable for use as tools, dies, and machine parts, which require a good combination of hardness and toughness..
