According to the "Steel Classification" standard, according to the basic performance and usage characteristics, spring steel belongs to mechanical structural steel. According to the quality grade, it belongs to special quality steel, that is, during the production process Steel that requires particularly tight control over quality and performance. According to Chinese custom, spring steel is a special steel. The technical requirements for making spring steel are relatively high. Excellent technology directly determines the quality.
Dongguan Bogang Metal Materials Co., Ltd.
is a large enterprise specializing in the production and sales of metal materials. Over the years, the company's high-quality services have deeply won the support and trust of customers across the country. We provide a variety of high-quality mold steels and undertake large-scale milling and grinding processing, heat treatment, and one-stop services, providing customers with a variety of choices.
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 .%~.%. According to its manganese content, it is divided into two categories: general manganese content (mass fraction) (.%~.%) such as,,, and higher manganese content (mass fraction) (.~.%).
Alloy spring steel
Alloy spring steel is based on
carbon steel
by appropriately adding one or several
alloying elements
Improve the mechanical properties, hardenability and other properties of steel to meet the performance requirements of manufacturing various springs.
The basic series of alloy spring steel include silicon-manganese spring steel, silicon-chromium spring steel, chromium-manganese spring steel, chromium-vanadium spring steel, tungsten-chromium-vanadium spring steel, etc. On the basis of these series, some brands have added alloying elements such as molybdenum, vanadium or boron in order to improve their performance in certain aspects.
In addition, some grades are also selected as spring steel from other steel types, such as
High-quality carbon structural steel
Carbon tool steel
High-speed tool steel
Stainless steel .
Bo Steel
The technical requirements of Bogang Metal are that spring steel should have good hardenability and low overheating and decarburization sensitivity. Reducing spring surface roughness can improve fatigue life.
Bo Steel Metal
In order to obtain the required properties, spring steel must have a high carbon content. Carbon spring steel means that the carbon content is within the range of .%.%. Due to the poor hardenability of carbon spring steel, it is only used to manufacture springs with cross-sectional dimensions not exceeding For springs with larger cross-sections, alloy spring steel must be used. The carbon content of alloy spring steel is between . The body and refined particles can effectively improve the mechanical properties of spring steel, among which r can also improve the high-temperature strength of steel.
Bosteel Metal
In recent years, combined with my country's resources and according to the requirements of new technologies in automobile and tractor design, new steel types have been developed based on silicon-manganese steel with boron, niobium, molybdenum and other elements added. The service life of the spring is extended and the quality of the spring is improved.
