15CrNiMo standard composition properties
15CrNiMo alloy steel has high yield strength and good toughness, and is suitable for working under high stress and impact loads. 15CrNiMo case hardened steel has excellent anti-wear properties and is suitable for manufacturing parts and tools that require good wear resistance. 15CrNiMo can be cut, forged and welded through general processing methods, and has good processability.
use:
Gears and transmission parts: Due to its high strength and good wear resistance, 15CrNiMo is often used to manufacture parts such as gears, reducers and transmission shafts, and is widely used in automobiles, ships, aerospace and other fields.
Forging manufacturing: 15CrNiMo is used to manufacture forgings that require high strength and wear resistance, such as forged shafts, forged gears, forged rods, etc.
Mechanical parts: 15CrNiMo is used to manufacture various mechanical parts, including crankshafts, connecting rods and drive shafts, etc., showing good performance in high load and high stress working environments.
Heat treatment:
Solid solution treatment: Heat 15CrNiMo to 850°C-880°C, hold it for a period of time and then cool quickly to improve its hardness and strength.
Normalizing treatment: After solution treatment, 15CrNiMo is heated to 870°C-890°C and then cooled by water quenching or oil quenching. This results in high hardness and appropriate toughness.
Tempering treatment: After normalizing, 15CrNiMo can be tempered. Control the heating temperature at 150°C-300°C. Keeping it in this temperature range for a period of time can reduce internal stress and improve toughness.
