Product DescriptionProduct DescriptionOil tempered spring steel wire is produced after final drawing, through two consecutive heat treatment processes: quenching (austenitization followed by rapid cooling) and high-temperature tempering."Oil quenching" refers to heating the wire to the austenitizing temperature and then rapidly cooling it in oil (quenching), transforming it into a high-hardness, high-strength martensite structure."Tempering" refers to heating the brittle martensitic steel wire after quenching to a relatively low temperature, holding it for a period of time, and then cooling it. This process eliminates internal stresses, improves toughness and ductility, and ultimately produces a tempered bainite structure.This "quenching + tempering" process imparts excellent combined mechanical properties, combining extremely high strength with good toughness.SpecificationNominal Diameter(mm)Allowable Deviation(mm)Tensile Strength (MPa)Minimum section shrinkage rateZ%FDCFDCrVFDSiCrFDSiCrVFDCFDCrVFDSiCrFDSiCrV5.00<d≤5.60±0.0351470-16201540-16901800-19502010-1960383838385.60<d≤6.00±0.0401460-16101520-16701780-19301960-21106.00<d≤6.501400-15501510-16601760-19101960-2110353535356.50<d≤7.001430-15801500-16501740-18901960-21107.00<d≤8.00±0.0451400-15501480-16301710-18601910-20508.00<d≤8.501380-15301470-16201700-18501980-2030323232328.50<d≤10.00±0.0501360-15101450-16001660-18101870-201010.00<d≤12.00±0.0701320-14701430-15801620-17701830-19703030303012.00<d≤14.00±0.0801280-14301420-15701580-17301790-193014.00<d≤15.001270-14201410-15601570-17201780-1920-1.

Automotive IndustryValve Springs: Engine valve springs operate at high temperatures and frequencies, placing extremely stringent demands on fatigue life and anti-relaxation properties. They are almost exclusively manufactured from high-grade, oil tempered steel wire.Clutch Springs: Used to transmit and cut power.Suspension Springs: Include coil springs and torsion bar springs.Brake Springs: Used to return and maintain brake pad position, requiring high safety.Stabilizer Bars: Connect the left and right suspension components to suppress vehicle body roll. 2. Mechanical Manufacturing and Industrial EquipmentValve SpringsShock Absorber Springs: Used not only in automobiles but also in the shock absorption systems of motorcycles, railway vehicles, and industrial machinery.4. Other IndustriesPetroleum Industry: Used as spring components in oil drilling tools.Aerospace: Special grades of oil tempered spring steel wire are used in applications where weight and performance are crucial.Sports Equipment: For example, the front fork shock absorber springs of high-end bicycles.Workshop DisplayPacking & DeliveryThe packaging is mostly roll packaging, and the delivery cabinet is packed with iron racks or wooden boxes. The specific requirements can be determined according to customer requirements.Company ProfileGongyi Hengming Metal Products Co., Ltd.Hengming Metal Group, established in 2005, is headquartered in Gongyi City, Henan Province, China.
