Spring steel (GB 1222-64) (1)

Spring Steel (GB 1222-64) (1) Introduction Spring steel is a special type of steel that is used in the production of springs and other related products. It is a high carbon steel with a tensile strength range of between 35 to 75 kg/mm². The main chemical elements that make up spring steel are manganese, silicon and phosphorus, with the addition of other elements, such as nickel and chromium, for additional strength and chemical resistance. Spring steel is highly malleable, which makes it ideal for applications in which the steel needs to be formed into a desired shape. It is also extremely durable and resistant to physical wear, which makes it particularly well-suited for use in applications that require repeated movement or use. Applications Spring steel is widely used in the production of flat, wave and coil springs, as well as other related products, such as motor and bicycle chains, shock absorbers, rollers and bushings. Springs made using spring steel are particularly suited for applications and environments that require the utmost levels of resistance to corrosion, rust and wear. Due to its physical and chemical properties, spring steel is also highly resistant to fatigue and impact, which makes it especially suitable for use in applications that involve frequent movement or mechanical stress. It is highly formable and malleable, making it ideal for applications where the shape of the steel needs to be tailor-made or where springs need to be formed into complex shapes. Spring steel is also used in the production of knife blades, as the high hardness and malleability of the steel leads to harder and more corrosion and wear-resistant blades. Production and Procurement Process Spring steel is produced using a combination of cold and hot working processes and heat treatments. The production process begins with the forming of the steel using either rolling or forging techniques. The steel is then treated to achieve the desired properties and hardness, through the use of heat treatments such as tempering, annealing and hardening. After this, the steel is tested for compliance and then cut into the desired size and shape. Spring steel is usually sourced from specialist suppliers or manufacturers who specialize in the production and supply of high-grade spring steel products for a variety of applications. The production process for spring steel is highly dependent on the chemical elements present in the steel and the level of quality that is required for a particular application. Quality Control Special tests are performed to ensure that the spring steel meets the required standards for a given application. These tests include hardness tests, chemical tests, tensile tests and surface evaluations. The results of these tests are then used to determine the quality and suitability of the spring steel for its intended use. In addition, spring steel manufacturers often conduct their own additional tests to verify the quality of the steel and its suitability for a given application. Conclusion Spring steel is a special type of steel that is used in a variety of applications due to its unique properties of malleability and resistance to corrosive wear. It is produced using a combination of cold and hot working processes and heat treatments and is usually sourced from specialist suppliers. Special tests are performed to ensure that the spring steel meets the required standards for its intended use.
