Product Feature:
1.High strength and elasticity
It is made of 65Mn spring steel, with a tensile strength of 735-925 MPa and a yield strength of 520-690 MPa, which can withstand high-frequency compression and heavy-load impact, stable resilience, and no deformation after long-term use.
Manganese significantly improves the hardenability, and the hardness of the oil is uniform after quenching for sizes below φ12mm, ensuring consistent spring performance.
2.Wear-resistant and corrosion-resistant
The surface is blued to enhance the anti-rust ability, adapt to humid or industrial corrosive environments, and prolong the service life.
Manganese content of 0.9%-1.2% optimizes wear resistance for high-friction applications (e.g. mechanical transmission components).
3.Precise heat treatment process
Strictly follow the 830°C quenching and 540°C tempering process to eliminate internal stress, balance hardness and toughness, and the fatigue limit is comparable to that of alloy springs.
After the optimization of the cold drawing annealing process, the grain is refined, the tensile strength reaches 600-620 MPa, and the plasticity is increased by more than 40%.
4.Customized service
Support non-standard size (WD: 0.2mm-WD: 8mm) customization, provide cold rolling, hot rolling multi-specification options, flexible adaptation to customer needs.
Surface treatment solutions such as nickel plating and coating can be provided to enhance the applicability of specific scenarios.
