42CrMo4 alloy steel
Grade:1.7225/GB 42CrMo, 38XM, AISI 4140/4142, BS 708M40/708A42/709M40, NF 40CD4/42CD4, DIN 41CrMo4/42CrMo4, JIS SCM4, ISO 683/1 3
Chemical composition:
C | Si | Mn | S | P | Cr | Ni | Cu | Mo |
0.38~0.45 | ≤0.40 | 0.60~0.90 | ≤0.035 | ≤0.035 | 0.90~1.20 | ≤0.030 | ≤0.030 | 0.15~0.30 |
Main features:
• Good purity and homogeneity.
• Good machinability
(Roughing, grinding and drilling).
• Good dimensional stability during heat treatment.
• Excellent preparation for nitriding, both ionic and gaseous, induction hardening to increase the mechanical properties.
• Poor solderability
Applications:
• Shafts, gears, cylinders and columns for industry
mechanics in general.
• Construction of mold
• For compression molds, where the etching is not required.
• Mechanical parts in general.
Heat treatment:
Normalization: heating to 840 to 880 ° C, maintenance, furnace cooling to 600 ° C, then in air.
Stress relieving: after rough heat to 500 ° C,
maintenance raff. In oven to 400 ° C, then in air.
Hardening: preheating from 600 to 650 ° C austenitizing
at 840 to 880 ° C, quenching in oil.
Tempering: heating to 550 - 650 ° C and maintenance regime, again depending on the mechanical properties
to be obtained.
