For ten years, Lispring has been focusing on the R&D and production of wave springs and spiral retaining rings in the past, present and future, aiming to provide reliable and satisfactory products to global high-tech customers. We welcome your inquiries at any time.
1.Carbon steel and alloy steel: When manufacturing springs, metal elements such as silicon, manganese, chromium, vanadium, and molybdenum are often added to the steel to increase the elasticity and fatigue limit of the springs and make them more impact-resistant.
2.Large wave springs are mostly processed by hot working, which means the spring material is rolled into rods at high temperatures and then processed and shaped at high temperatures. After that, it is quenched in oil or water at temperatures of 780°C to 850°C and then tempered at temperatures of 400°C to 500°C.
3.For small springs, they are first annealed and then processed by cold working. After being coiled, they are hardened and tempered, such as wire, piano wire, or steel strip.
4.Piano wire is made of high-carbon steel (0.65% to 0.95%) with less impurities. When the diameter is often less than 1/4, it is drawn into wire at room temperature after annealing. Its mechanical properties are excellent, with high tensile strength and toughness, making it a good material for spiral springs.
5.Stainless steel wire is used in places that are easily corroded. For high temperatures, high-speed steel and stainless steel can be used.
6.Oil-tempered wire with a carbon content of 0.6% to 0.7% should contain manganese, and 0.6% to 1.0% is often used for spiral springs.
7.Leaf springs commonly use 0.9% to 1.0% plain steel, while the more advanced ones use chrome-vanadium steel and silicon-manganese steel.
