42CrMo Steel Parts CNC Machining 42CrMo4 Accessory Components
42CrMo Steel Parts Belongs To The Plastic Die Steel In The Die Steel In Terms Of Material Classification, Which Has Good Mechanical Properties And Machining Ability. It Is Widely Used, Mainly In Sheet Metal, Round Bar, Forged Steel, Cast Steel And Other Types Of Materials, In Which Steel Plate Is Used For Die Processing And Production, Steel Round Bar Is Used For Mechanical Direct Processing Parts, Has Been Recognized By The Industry.
CNC Machining 42CrMo Components Belongs To Ultra-High Strength Steel With High Strength And Toughness, Good Hardenability, No Obvious Temper Brittleness, High Fatigue Limit And Multiple Impact Resistance After Quenching And Tempering Treatment, And Good Low Temperature Impact Toughness.
Large And Medium-Sized Plastic Moulds With Certain Strength And Toughness Are Suitable For Manufacturing 42CrMo Steel Accessory.
Chemical Composition Of 42CrMo Steel Parts
C: 0.38～0.45%
Si: 0.17～0.37%
Mn: 0.50～0.80%
S: Allowable Residual Content ≤0.035%
P: Allowable Residual Content ≤0.035%
Cr: 0.90～1.20%
Ni: Allowable Residual Content ≤0.30%

42CrMo CNC Machining Accessory Mechanical Property
Hardness: Annealed, 255-207HB,
The Indentation Diameter Ranges From 3.8 mm to 4.2 mm.
Quenching: > 60HRC
The Hardenability, Hardness, Strength And Toughness Of Cr12MoV Sheet After Quenching And Tempering Are Higher Than Those Of CR12. The Hardenability Of Cr12MoV Sheet With Diameters Below 300 Mm To 400 Mm Can Be Completely Quenched, And The Quenching Deformation Is Small, But The High Temperature Plasticity Is Poor.
Cr12MoV Sheet Is Mostly Used To Manufacture Hybrid Dies And Tools With Large Cross Section, Complex Shape And Heavy Workload.
