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(%)
C | Si | Mn | Cr | Mo | P | S | Ni |
0.38~0.45 | 0.17~0.37 | 0.60~0.90 | 0.90~1.20 | 0.15-0.25 | ≤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.
