    Alloy Steel Round Bar 42CrMo/SAE4140/SCM440/1.7225 For Mechanical

    Alloy Steel Round Bar 42CrMo/SAE4140/SCM440/1.7225 For Mechanical


    Product Introduction
    SAE 4140 alloy steel is chromium, molybdenum, manganese containing low alloy steel. It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength.

    Chemical Composition(%)

    CSiMnCrMoPSNi
    0.38~0.450.17~0.370.60~0.900.90~1.200.15-0.25≤0.018≤0.030≤0.012

    Features
    1) Weldability suffers with increasing chromium content;
    2) High temperature strength and high pressure hydrogenation properties are promoted by chromium and molybdenum;
    3) Molybdenum significantly reduces temper brittleness;
    4) Chromium renders steel oil hardenable and increase hardenability;
    5) Chromium molybdenum high tensile steel with yield strength of 550N/mm2;

    Mechanical Properties:
    Tensile strength:σb (MPa):≥1080(110)
    Yield strength:σs (MPa):≥930(95)
    Elongation:δ5 (%):≥12
    Section shrinkage:ψ (%):≥45
    Impact work:Akv (J):≥63
    Impact toughness value:αkv (J/cm²):≥78(8)

    Applications
    It used for section large forgings, such as locomotive traction gears, with supercharger drive gear, the rear axle, the connecting rod and the spring load greatly clip,oil drill pipe joints and fishing tools,etc.
