Product Description
We can produce and supply various specifications spring steel coil, spring steel strip, carbon steel coils, etc.
Spring steel belt is a kind of spring steel, and spring steel refers to special alloy steel for manufacturing various springs and other elastic components. According to performance requirements and service conditions, it can be divided into ordinary spring alloy steel coil and special alloy spring steel.
1. Classification according to chemical composition
According to the 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.
carbon spring steel
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
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.
Second, according to the classification of production and processing methods
1. Hot-rolled (forged) steel products include hot-rolled round steel, square steel, flat steel, steel plate, forged round steel and square steel.
2. Cold-drawn (rolled) steel products include steel wire, steel strip, and cold-drawn material (cold-drawn round steel).
