Hardened and tempered spring steel strip is a type of high-carbon steel product that has undergone specific heat treatment processes to give it the desired mechanical properties for use in applications where high strength and elasticity are required. This type of steel is commonly used in the manufacturing of various types of springs, such as coil springs, flat springs, and other components where flexibility and resilience are essential.

Here are the key steps involved in producing hardened and tempered spring steel strip:

1. Material Selection: The base material is typically a high-carbon steel with a carbon content ranging from 0.6% to 0.9%. The high carbon content provides the steel with its spring-like properties.

2. Hot Rolling: The steel is initially hot-rolled to reduce its thickness and achieve the desired dimensions. Hot rolling involves passing the steel through a series of rollers while it's heated to shape and refine the material.

3. Annealing: After hot rolling, the steel strip is subjected to an annealing process to relieve internal stresses and make the steel more workable. Annealing involves heating the steel to a specific temperature and then gradually cooling it down. This process can make the steel softer and more ductile.

4. Hardening: The steel strip is heated to a high temperature, typically above its critical temperature, and then quickly quenched in a cooling medium, such as oil or water. This rapid cooling "freezes" the steel's internal structure, making it hard and strong. The specific hardening temperature and cooling method depend on the desired spring properties.

5. Tempering: To achieve the right balance of hardness and toughness, the hardened steel strip is tempered by heating it to a lower temperature, typically below the critical point but above room temperature. This reduces the brittleness introduced during hardening and imparts the necessary elasticity and resilience.

6. Finishing: The steel strip is then often further processed through cold rolling, grinding, or other finishing operations to achieve the desired thickness, surface finish, and dimensional accuracy.

The resulting hardened and tempered spring steel strip has the following characteristics:

• High tensile strength.
• Good elasticity and resilience.
• Resistance to deformation and fatigue.
• Reliable spring properties.
• Typically a polished or blued surface finish to improve corrosion resistance.

These strips are used in various applications, including automotive suspensions, industrial machinery, hand tools, and more, where springs are required to endure repetitive cycles of compression and expansion while maintaining their performance characteristics. The specific properties of the steel strip can be tailored to meet the requirements of the intended application.

A spring steel strip that is 1mm thick, hardened, and tempered is a specific type of spring material that has undergone heat treatment processes to achieve desired mechanical properties. The hardening and tempering processes are crucial steps in enhancing the strength, toughness, and resilience of the spring steel. Here's what each of these terms means in the context of spring steel:

1. Thickness: The term "1mm" indicates the thickness of the spring steel strip. This measurement is important as it determines the strength and flexibility of the strip.

2. Hardened: Hardening is a heat treatment process that involves heating the steel to a temperature above its critical point and then rapidly cooling it, often through quenching. This process increases the hardness of the steel by transforming its microstructure. Hardened spring steel is capable of withstanding higher stress and providing better wear resistance.

3. Tempered: Tempering is a subsequent heat treatment process that involves reheating the hardened steel to a lower temperature. This imparts additional toughness and reduces brittleness. Tempering helps balance the hardness achieved during hardening with improved ductility and toughness, making the steel suitable for applications where resilience is essential.

In the case of a 1mm thick hardened and tempered spring steel strip:

• Thickness: 1mm (the nominal thickness of the strip).

• Hardening: The steel has undergone a hardening process to increase its hardness, providing the strip with the strength required for its spring application.

• Tempering: After hardening, the steel has been tempered to achieve the desired balance of hardness and toughness. Tempering reduces the brittleness that can be associated with fully hardened steel and enhances the strip's ability to absorb and release energy, a critical characteristic for spring applications.

Applications of such hardened and tempered spring steel strips (1mm thick) can include various types of springs used in industries like automotive, electronics, industrial machinery, and more. The specific grade of spring steel and the tempering temperature will influence the final properties of the strip, and these choices are made based on the requirements of the intended application.
