Information Name: | Supply 42crmo alloy structural steel |
Published: | 2012-04-17 |
Validity: | 900 |
Specifications: | Complete |
Quantity: | 8562.00 |
Price Description: | |
Detailed Product Description: | 42CrMo China's implementation of standards GB / T 3077-2006 The corresponding ISO grade: 42CrMo4 Corresponding to Japanese Grade: SCM440 Corresponding German Grade: 42CrMo4, or 1.7225 Approximation corresponds to U.S. grades: 4140 G41400 ● Features and Scope: Strength, high hardenability and good toughness, small deformation, quenching, high creep strength and rupture strength at high temperatures. Used in the manufacture require forging greater than the higher intensity of 35CrMo steel and quenched and cross-section, such as locomotive traction gears, the supercharger drive gear, pressure vessels, gear, rear axle, by a great load of the connecting rod and collet can also be used below 2000m deep oil drill pipe joints and fishing tools, and can be used in the mold of the bending machine. Chemical composition Carbon C: 0.38 ~ 0.45% Silicon Si: 0.17 ~ 0.37% Mn Mn: 0.50 ~ 0.80% Sulfur S: Allow the residual content ≤ 0.035% Phosphorus P: Allow the residual content ≤ 0.035% Chromium Cr: 0.90 ~ 1.20% Ni: to allow the residual content ≤ 0.030% Cu: to allow the residual content ≤ 0.030% Mo Mo: 0.15 to 0.25% The 42CrMo allowable stress of 186 ~ 310/MPa yield the point 930σs/MPa, 42CrMo strength, high hardenability and good toughness, quenched deformation at high temperatures, high creep strength and rupture strength. 42CrMo used in the manufacture require forging greater than the higher intensity of 35CrMo steel and quenched and cross-section Mechanical properties Tensile strength σb (MPa): ≥ 1080 (110) Yield strength σs (MPa): ≥ 930 (95) Elongation δ5 (%): ≥ 12 Reduction of area ψ (%): ≥ 45 Impact energy Akv (J): ≥ 63 Impact the toughness the value αkv (J/cm2): ≥ 78 (8) Hardness: ≤ 217HB |
