AISI 4140 steel is the stand of the USA. And the GB 42CrMo steel has the same properties and chemical composition for 4140 steel in China. But at the part of extensibility is lower than 4140. But the gap is not big. It is high has high strength and toughness. And the hardening capacity also is good. After the processing of hardening and tempering, the shock resistance capability and fatigue value will be getting better.
Carbon: 0.38%-0.43%
Silicon: 0.15%-0.35%
Manganese: 0.75%-1.00%
Sulfur: ≤0.040%
Phosphorus: ≤0.030%
Chromium: 0.80%-1.10%
Nickel: ≤0.030%
Copper: ≤0.030%
Molybdenum: 0.15%-0.25%
Mechanical Property:
Intensity of tension: ≥110MPa
Yield Strength: ≥95MPa
Hardness: ≤217HB
After the heat treatment, its total properties will be improved. Such as strength and mechanical properties. Its technological properties are good, the lumber recovery also at a high level. The highest temperature of use is 427℃. It is used to make the forgeable piece with high strength and big section of quenching and tempering.
As a professional 4140 steel supplier, lots of 4140 steel round bar and sheet are on stock. Welcome to visit our factory and warehouses.
