15CrMo Steel Bar

15CrMo is an alloy structural steel composed mainly of carbon, silicon, and other alloying elements. It is classified as a heat-resistant steel that maintains good strength and machinability even at elevated temperatures of around 500–550°C. This grade of steel is known for its excellent strength, toughness, and corrosion resistance, making it suitable for manufacturing critical components such as gears, crankshafts, and seamless pipes.

Key Features of 15CrMo Steel:

• Low-alloy, heat-resistant steel

• Higher strength compared to 12CrMo steel, with slightly lower toughness

• Maintains good performance at temperatures up to 500–550°C

• Excellent resistance to heat and oxidation

• Good mechanical properties and machinability

• Decent cold forming (plastic deformation) capability

• Weldability is acceptable

• Widely used in the production of seamless steel pipes of various sizes and steel plates
