PRODUCT DESCRIPTION
Spring Steel Sheet In Coil Spring Steel Strip belongs to spring steel.
Spring steel refers to steel specially used to manufacture springs and elastic elements due to its elasticity in the quenched and tempered state. The elasticity of steel depends on its ability to deform elastically, that is, within a specified range, the ability to deform elastically allows it to withstand a certain load without permanent deformation after the load is removed. Spring steel should have excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit, yield ratio), anti-elasticity reduction performance (that is, anti-elasticity reduction performance, also known as anti-relaxation performance), fatigue performance, hardenability , Physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, corrosion resistance, etc.). In order to meet the above performance requirements, spring steel has excellent metallurgical quality (high purity and uniformity), good surface quality (strict control of surface defects and decarburization), precise shape and size.
Spring steel is divided into non-alloy spring steel (carbon spring steel) and alloy spring steel according to its chemical composition.
The carbon content (mass fraction) of carbon spring steel is generally 0.62%~0.90%. According to its manganese content, it is divided into general manganese content (mass fraction) (0.50%~0.80%) such as 65, 70, 85 and higher manganese content (mass fraction) (0.90~1.20%), such as 65Mn.
Alloy spring steel is based on Carbon Steel, by properly adding one or several alloying elements to improve the mechanical properties, hardenability and other properties of steel, so as to meet the steel required for the manufacture of various springs.
The basic composition series of alloy spring steel are silicon-manganese spring steel, silicon-chromium spring steel, chromium-manganese spring steel, chrome-vanadium spring steel, tungsten-chrome-vanadium spring steel, etc. On the basis of these series, some grades have added alloying elements such as molybdenum, vanadium or boron in order to improve their performance in some aspects.
In addition, some grades are selected from other steels, such as high-quality Carbon Structural Steel, carbon tool steel, high-speed tool steel, and Stainless Steel, as spring steel.
