Oil Tempered Spring Steel Wire
We supply premium oil tempered spring steel wire with grades 65Mn, 72B, 82B, 60Si2Mn, 55CrSi and SWOSC-V, wire diameter from 0.5mm to 14mm. Stable raw material supply and standardized thermal processing ensure consistent mechanical performance of each oil tempered spring steel wire.
High-Performance Characteristics
Ultra-high strength
Oil quenching greatly improves tensile strength to bear heavy loads for industrial elastic parts.
Balanced toughness
Matching tempering procedure prevents brittle fracture under frequent cyclic deformation.
Long fatigue lifespan
Optimized comprehensive mechanical properties delay fatigue crack generation under long-term repeated operation.
Stable batch performance
Precise process control minimizes property deviation between different production batches.
Surface & Material State
Available surface finishes: bright finish, oxide finish and phosphating coating. The wire is fully oil quenched and tempered, ready for direct coiling without extra heat treatment.
Application Scope
Ideal for automotive springs, engine valve springs, shock absorber springs and all heavy-duty high-strength springs.
Stable Supply of High-Grade Raw Materials
Baoding Zhongxin Spring Manufacturing Co., Ltd. provides both conventional carbon steel wire and high-end oil tempered spring steel wire for downstream clients. We maintain deep long-term cooperation with top steel mills to secure stable supply of premium raw coil stock, including high-spec SWOSC-V wire. Every production procedure is strictly controlled to fully release the intrinsic high-performance mechanical properties of raw materials. Whether customers need general specification wire or high-end tempered wire, we can deliver stable, qualified products to match diverse performance demands.
