Grade 42CrMo4 1.7225

Grade 42CrMo4 1.7225

一, 42CrMo4 is an alloy structure steel plate, 42CrMo4 is used to manufacture forgings that require higher strength and larger tempered cross section than 35CrMo steel. Such as large gear for locomotive traction, booster transmission gear, rear shaft, connecting rod and spring clamp with great load, 42CrMo4 can also be used for drilling pipe joints and fishing tools in deep oil Wells below 2000m.

二, 42CrMo4 implements the European standard EN 10083/3-2006 standard, number 1.7225. 42CrMo Execute GB/T 3077-1999.

三, 42CrMo4 and 42CrMo steel plate is ultra-high strength steel, with high strength and toughness, hardenability is also good, no obvious tempering brittleness, high fatigue limit and resistance to multiple shocks after tempering treatment, low temperature impact toughness is good. 42CrMo steel is suitable for the manufacture of large and medium-sized plastic molds requiring certain strength and toughness.

四, 42CrMo4 steel plate chemical composition:

Carbon C :0.38-0.45%;

Silicon Si:0.17-0.37%;

Manganese Mn:0.50-0.80%;

Sulfur S: Allowable residual content ≤0.035%

P: Allowable residual content ≤0.035%;

Chromium Cr:0.90-1.20%;

Nickel Ni: Allowable residual content ≤0.030%

Copper Cu: allowable residual content ≤0.030%;

Molybdenum Mo:0.15-0.25%

五, 42CrMo4 steel plate mechanical properties:
