High Carbon Spring Steel Coil
Steel is strong and durable and able to withstand a great deal of stress and strain. This makes it an ideal material for springs.
Coil springs can be made from a wide variety of metals including high and medium carbon spring steel, chromium silicon steel, nickel chromium alloys, and various grades of stainless steel.
Tensile Strength
High carbon spring steel coil has an extremely high tensile strength and hardness. This makes it an ideal material for flat springs, clips and blades. It is also easier to form than mild steel grades.
Low-carbon steel, or mild steel, has a comparatively low radio of carbon to iron. This gives it a lower strength and is less malleable than medium-carbon steel.
Medium-carbon steel contains between 0.3% and 0.6% carbon, which makes it a perfect choice for many different uses. This alloy provides a balance of workability, price and durability. High-carbon steel is a tough metal with higher levels of carbon, which allows it to be heat treated into very strong parts.
Because springs work under alternating stresses for long periods of time, they require a very high fatigue limit and resistance to creep and relaxation. Springs used in corrosive environments must spring steel coil have corrosion resistance, too. Coiling Technologies offers various coating and plating solutions to ensure springs made from AISI 5160H do not corrode when exposed to their environment.

Corrosion Resistance
Corrosion resistance is a critical component of spring strength, as corrosion can decrease the surface area and thus reduce the tensile strength of the metal. This is especially true in situations where a spring is exposed to the elements, such as in an outdoor environment or in a high humidity location.
Alloying elements can be added to increase a steel’s corrosion resistance. For example, chromium can form a dense Cr2O3 oxide film on the steel’s surface, which protects it from further corrosion. Additionally, chromium can be alloyed with other metals to increase its corrosion resistance. These alloys can include copper, nickel, cobalt, manganese, molybdenum, vanadium, and tungsten.
The corrosion resistance of a spring can also be affected by the housing or casing that it’s housed in. Using gaskets and seals can help ensure that the housing is airtight, which will prevent corrosive substances from entering the spring. Additionally, the spring can be designed with a smaller cross-sectional area to reduce its exposure to corrosive environments.
Spring steels can be used for a variety of applications, including clips and fasteners. Because of their durability and fatigue resistance, they are frequently used to create clips that hold wires together. In addition, they can be used to make flat springs for electrical parts like switches. Stainless springs are also available, such as Type 302 and 17-7 PH, which have excellent corrosion resistance and can withstand higher temperature limits than carbon steels.
Heat Treatment
While spring steel is a great material for springs, it is also used in other parts that require components capable of absorbing and re-exerting force. These include the spring diaphragms in automobiles and seat belt retractors. These springs must be able to absorb and re-exert force without being permanently deformed. In order to achieve this, these parts must be made with a high yield strength.
To achieve a high yield strength, the steel needs to be heat treated after being formed into its final shape. This is done by heating the steel to a very high temperature and then quenching it in oil. The quenching oil must be specially selected for this process. This type of treatment gives the steel good ductility, less internal stress, and distortion.
Another type of heat treatment is tempering, which involves reheating the steel to around the austenitizing temperature and cooling it very slowly. This results in the formation of martensite, which provides good ductility and toughness. This type of heat treatment also improves the fatigue properties of the steel.
The research presented here focuses on optimizing the heat treatment of large Ph13 mm 38Si7 spring steel for railway clips. A multi-factor, three-level experimental design was used to examine the effect of quenching temperature, holding time, and tempering temperature on the microstructure, mechanical properties, decarburization behavior, and fracture morphology of this type of spring steel.
Formability
If you’re looking for steel that Stainless Hardened SteelStrip can be formed without losing its strength, medium or high carbon spring steel might be the right option. This specific steel is able to hold its shape after a great deal of bending and twisting, making it ideal for applications like springs and retaining clips.
While you might think of springs when thinking of this particular type of steel, it’s actually used for a lot of other products and industrial applications. From airplane parts, to backup sensors in your car, to binder clips and tape measures, there are many places you can find spring steel.
This is especially true if the material has been hardened and tempered, which increases its formability. When compared to regular or alloy steels, spring steel is more resilient, has a higher tensile strength, and can be bent and twisted without losing its shape.
While there are other metals that can be shaped into the desired form, spring steel is generally considered to be one of the best choices for this purpose.
