Spring Steel

A reliable source for Spring Steel information and leading Spring Steel Companies.

The term “spring steel” describes a class of low alloy, medium-to-high carbon steel products with outstanding yield strength. Yield strength is the ability of a material to withstand severe bending and return to its original shape without deforming. Silicone is often present in spring steel stock alloys. These alloys are hardened, and cold rolled to increase yield strength. Spring steel is often cold drawn as wire or punched from flat stock to produce the final product. Saw blades, tape measures, helical springs, and car suspension parts are typical applications. Read More…

Spring Steel Spring steel is a steel variety characterized by its resistance to impact and deformation. Spring steel features medium to high levels of carbon, which, when increased or reduced in a steel affects its properties of hardness and oxidation resistance.

Flat Spring Steel

The special property of spring steel alloys is their ability to sustain strong twisting or bending forces without distorting. These steel alloys allow for continuous bending, compression, extension, and twisting. Spring steel alloys have a medium-to-high carbon content. Manganese and silicone are frequently used as additional alloy additives, with silicone as the foundation for high-yield strengths.

Since heating spring steel after manufacture could harm the alloy's resilience, the alloy stock is operated cold after casting to preserve and enhance yield strength. Spring steel components normally can’t be welded unless they are retempered later. Instead, the alloys are typically hardened to Rockwell C values between 42 and 60, then cold drawn or rolled into flat sheets or wire stock. After that, products are coiled with wire or punched from flat plates. Often, intricate pieces are created from soft, annealed stock and only hardened after they are finished.

Applications of Spring Steel

The silicon added to spring steel during the alloying process gives it the strength to withstand impacts and asymmetrical bending. Silicon enables the metal to stretch and bend without sustaining permanent damage. Spring steel is an excellent raw material for manufacturers requiring sturdy, heat- and abrasion-resistant metal. Different types of spring steel have varying degrees of flexibility and hardness. For instance, machine components, gun parts, knives, small files, mechanical springs, clips, and anything else needing the characteristics of high carbon are all made from cold-rolled, annealed spring steel.

However, blue-tempered steel is more reasonably priced and is often used to make blades for healthcare facilities, flat springs, motor springs, steel tapes, valves, and reeds. Spring steel is a common material used to make molds for plastic injection molding. Certain types of music wire, such as piano and guitar strings, can also be made from spring steel.

Manufacturing Process

Steel service providers use a wide range of steel working techniques to give steel various properties. The properties that make the various spring steel kinds usable depend on a particular steelworking technique. For instance, when heating tempered spring steel, flexibility and impact resistance aren't sacrificed to increase hardness. Steel that has been annealed is heated until it becomes malleable, but the temperature is always kept below the steel's recrystallization temperature. To enhance the metal's performance at high temperatures, heat-treated spring steels may include additions like cobalt and nickel.

Spring steel might undergo other production procedures to improve its qualities, including quenching in water or oil and following heat treatments to cool and harden the steel. Another post-heat-treatment hardening technique is air hardening, which can be more cost-effective and equally effective than quenching techniques. Slitting, edging, leveling, and other physical shaping techniques can modify the shape of spring steel to meet standards.

Advantages of Spring Steel

The most distinguishing quality of spring steel is its simplicity in coiling into a helix shape, which enables it to store energy when compressed and release it when expanded. In this respect, elastic materials with good strength might be characterized as spring steels.

Additionally, spring steel has a low hardness to bend without breaking or fracturing and great fatigue resistance. Its ability to bend or twist repeatedly over time makes it suitable for applications like door hinges, drawer slides, conveyor belts, and other machinery parts. Since spring steels have these characteristics, they have been used for ages.

Other Applications of Spring Steel

Since Spring Steel is an alloy recognized for its exceptional strength and elasticity, this makes it the ideal substance for several uses, such as:

  • Producing springs
  • Making automotive components like suspension systems
  • Constructing tools and machinery
  • Producing surgical equipment
  • Knife Production
