35CrMo Alloy Steel Wire

35CrMo alloy steel wire is a high-strength wire made from chromium-molybdenum alloy steel as the base material through quenching and tempering. It is mainly used for load-bearing parts, springs and mechanical connectors, and is suitable for bearing high loads or cyclic stress environments.

High Load Capacity

Tensile strength 900–1200 MPa, yield strength 650–900 MPa. Quenching and tempering create a martensitic + tempered microstructure in the steel wire.

Suitable for Precision Forming

Diameter 0.5–12 mm, can be cut or wound according to part design; elongation 10–15% ensures the material is not prone to cracking during tensile or winding processes.

Cyclic Stress Adaptability

Hardness controlled to ≤217 HB after heat treatment. Combined with alloying elements (Cr, Mo) to form a tough tempered microstructure, reducing the risk of fatigue fracture under repeated loads or vibration conditions.

Spring and Fastener Manufacturing: Used in tension and compression springs and high-strength bolts to ensure parts maintain performance under high loads and repeated deformation conditions.

Machinery Parts Industry: Used in shafts, pins, connecting rods, and small load-bearing structural components. The steel wire withstands impact and cyclic stress to ensure part durability.

Automotive and Construction Machinery: Used in high-strength connections and elastic elements in vehicles and machinery to maintain structural integrity under cyclic load conditions.

Energy and Heavy Industry: Used in wire ropes, traction components, and high-stress parts to withstand continuous cyclic loads and high tensile forces.
