Brief introduction:
In ASTM A681 standard, 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.
Application:
spindles,forming rolls,punches,blanking and forming dies,trimmer dies,clutch parts,pawls,bearings,chucks parts,rollers,knuckle pins,clutch pins,shear blades
