Details description
Chemical Composition
Carbon (C): 0.18%~0.23%, Silicon (Si): 0.15%~0.35%, Manganese (Mn): 0.90%~1.20%, Sulfur (S) ≤0.035%, Phosphorus (P) ≤0.035%, Chromium (Cr): 1.10%~1.40%, Molybdenum (Mo): 0.20%~0.30%.
Mechanical Properties
Hardness after annealing (HBW) ≤217. After surface hardening treatment: For 11mm diameter: Tensile strength: 1080-1370MPa, Yield strength: 735MPa, Elongation: 7%, Reduction of area: 30%, Impact energy: 27J; For 30mm diameter: Tensile strength: 980-1270MPa, Yield strength: 685MPa, Elongation: 8%, Reduction of area: 35%, Impact energy: 27J; For 63mm diameter: Tensile strength: 780-1080MPa, Yield strength: 540MPa, Elongation: 10%, Reduction of area: 35%.
Performance Characteristics
High hardenability: It can harden without external heat. Appropriate heat treatment can produce a uniform martensitic structure, increasing hardness and strength.
No temper brittleness: It is not prone to embrittlement during tempering, and has good heat treatment properties.
Good weldability: The tendency to form cold cracks is very small, making it easy to process through welding.
Good machinability: It has good machinability and cold strain plasticity, and excellent processing performance.
Product Specifications
Round steel diameters are typically 6mm-350mm, plate thicknesses are generally 6mm-300mm. Forgings, seamless tubes, and forged rings can also be produced according to requirements. Shapes and sizes can be customized.
Application Areas
It is commonly used to manufacture gears, bearings, transmission shafts, and other mechanical components. It can also be used in the manufacturing of automotive transmission system parts and engine parts. In addition, it is also used in the manufacturing of engineering machinery parts such as excavators and milling machines.
20CrMo5 is a high-strength alloy steel with excellent hardenability, wear resistance, and toughness, ideal for automotive and industrial components.
