What are the materials commonly used in the production of waveform springs, and where are they typically applied? Below, the editor will introduce it to you.
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 spring, and to make it resistant to impact.
2. Large waveform springs are often processed by hot work, which involves rolling the spring material into a rod at high temperature, forming it at high temperature, quenching it in oil or water at around 780-850 degrees, and then tempering it at a temperature of 400-500 degrees.
3. Small springs, first annealed, then cold worked, rolled, and then hardened and tempered, such as steel wire, piano wire, or steel strip.
4. Qin steel wire is made of high carbon steel (0.65-0.95%) with few impurities. When the diameter is usually less than 1/4, it undergoes toughening treatment and is drawn into wire at room temperature. Its mechanical properties are excellent, with high tensile strength and toughness, making it an excellent spiral spring material.
5. Stainless steel wire is used in areas prone to corrosion, and can withstand high temperatures using high-speed steel and stainless steel.
6. The carbon content of the oil return line should be 0.6-0.7%, which should contain manganese. 0.6-1.0% is commonly used for coil springs.
7. Plate springs are commonly made of 0.9-1.0% ordinary steel, while higher grade ones use chromium vanadium steel and silicon manganese steel.
