The smelting of SM490YB carbon steel plate sheet, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to have high purity. The content of sulfur, phosphorus, oxygen and nitrogen should be low, and the uniformity and stability of steel should be good. The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, spring steel must also have some characteristics.
