Description

Product:DIN 1.***4, AISI L6, Key words:tool steel, die steel, specialty steel, steel bar, hotwork, coldwork, forged bar, alloy tool steel, flat bar, round bar, plastic mould steel, steel bar, Typical Analysis: C : 0.***0.*5 Si : 0.***0.*0 Mn: 0.***0.*0 P : Max 0.**0 S : Max 0.**0 Cr: 0.***1.*0 Mo: Max 0.*0 Ni: 1.***2.*0 Similar Grades:DIN 1.***4, GB/T 5CrNiMo Advantages: Good toughness at lower hardness lever. Good wear at high hardness lever. Application: L6 was designed for general purpose tools where greater toughness is required, such as forming rolls, punches, blanking dies, shear blades, and spindles. Machinability: L6 has a machinability rating of *5% of a 1% carbon tool steel. Annealing: L6 should be annealed at ***0°F and held for one hour per inch of thickness. Cool at *0°F per hour to **0°F and then air-cool. A maximum hardness of **7 Brinell should be obtained. Hardening: L6 should be preheated to ***0°F then heated to ***0°to ***0°F and held for one hour per inch of thickness. Quench in oil to **0°F followed immediately by tempering. L6 can also be air quenched in sections less than 1" thick.
