Hot Sale 65Mn Spring Steel Round Bar With High Tensile Strength
Hot Sale 65Mn Spring Steel Round Bar With High Tensile Strength
Feature
-
Spring steel refers to the steel specially used to manufacture springs and elastic elements because of its elasticity in quenching and tempering conditions. The elasticity of steel depends on its elastic deformation ability, that is, within a specified range, the elastic deformation ability makes it bear a certain load, and there will be no permanent deformation after the load is removed.
1). Material: 65Mn , 55Si2MnB, 60Si2Mn, 60Si2CrA, 55CrMnA , 60CrMnMoA , as per customer’s requirement
2). Packing: standard sea-worthy packing
3). Surface treatment: punched, welded, painted or as per customer’s requirement
4). Size: according to customer’s requirement
1) According to the chemical composition classification
According to GB/T 13304 standard, spring steel is divided into non-alloy spring steel (carbon spring steel) and alloy spring steel according to its chemical composition.
①Carbon spring steel
②Alloy spring steel
In addition, some brands are selected as spring steels from other steels, such as high-quality carbon structural steel, carbon tool steel, high-speed tool steel and stainless steel.
2)According to the classification of production and processing methods
①Hot rolled (forged) steel includes hot rolled round steel, square steel, flat steel and steel plate, and forged round steel and square steel.
②Cold-drawn (rolled) steel includes steel wire, steel strip and cold-drawn material (cold-drawn round steel).
Springs are used under impact, vibration or long-term stress, so spring steel is required to have high tensile strength, elastic limit and high fatigue strength. In the process, it is required that spring steel has certain harden-ability, is not easy to decarburize, and has good surface quality.
As the name suggests, spring steel is used to manufacture various springs, including small-section flat springs, round springs, springs, etc. It can also be used to make valve springs, spring rings, shock absorbers, clutch reeds, brake springs, and leaf springs for small and medium-sized cars. , steam turbine steam seal spring, locomotive large leaf spring, coil spring, valve spring, boiler safety valve spring, etc.
