Spring Steel can be divided into two types. One is carbon spring steel, and other one is alloy spring steel.
Alloy spring steel is based on carbon spring steel, by adding one or more alloying elements to improve the mechanical properties, hardenability and other properties to meet the requirement for manufacture all kinds of spring steel.

- Q:What are the main applications of special steel in the agricultural sector?
- Special steel has various applications in the agricultural sector, including the manufacturing of agricultural machinery and equipment such as tractors, plows, and harvesters. It is also used for constructing storage silos, irrigation systems, and fencing materials. Additionally, special steel is utilized in the fabrication of cutting tools, blades, and parts for farming implements, ensuring durability and high performance in challenging agricultural environments.
- Q:What are the different heat treatment processes for special steel?
- Some of the different heat treatment processes for special steel include annealing, quenching and tempering, hardening, case hardening, and precipitation hardening.
- Q:How is special steel recycled?
- Special steel is typically recycled through a process called electric arc furnace (EAF) steelmaking. During this process, scrap steel, including special steel, is melted down in an electric arc furnace. The furnace reaches extremely high temperatures, causing the steel to melt. Once melted, the impurities are removed, and the steel is then refined and shaped into new products. This recycling method helps to conserve natural resources, reduce energy consumption, and minimize environmental impacts associated with traditional steel production.
- Q:What are the different methods for case hardening special steel?
- Case hardening special steel can be achieved through various methods, each with its own set of advantages and applications. 1. Carburizing: By subjecting the steel to high temperatures within a carbon-rich environment, a durable and resistant outer layer is formed as carbon atoms diffuse into the surface. Gas carburizing, pack carburizing, or liquid carburizing are some techniques employed for this process. 2. Nitriding: Steels with high alloy content benefit from nitriding, wherein the steel is heated in an environment abundant in nitrogen. This leads to the formation of a tough and corrosion-resistant layer as nitrogen atoms penetrate the surface. 3. Induction hardening: Through induction heating, the surface of the steel is selectively heated, followed by a rapid quenching process. This results in a hardened layer suitable for localized hardening requirements, such as gears or shafts. 4. Flame hardening: Large parts or components that are challenging to treat with other methods can be effectively hardened through the application of a high-temperature flame to the steel surface, followed by rapid cooling. 5. Laser hardening: Achieving precision and localized hardening, laser hardening involves the use of a laser beam to heat and harden specific areas of the steel. This method allows for precise control over the depth and hardness of the hardened layer. The selection of a case hardening method depends on various factors, including the desired hardness, the size and shape of the part, and the specific requirements of the application. Each method possesses its own advantages and limitations.
