Cold Rolled High Carbon Steel Spring Steel Strip
Cold rolled high carbon steel spring steel strip can be found in tools and other products that require a combination of strength, resilience, and durability. This type of metal can be formed and shaped into many different types of products, including hinges, clips, fasteners, and retaining rings.
It is hardened and tempered to increase its strength and resistance to damage. This process involves heating the steel above its critical temperature, then quickly cooling it.
High Carbon Content
High carbon steels are stronger and harder than medium-carbon and low-carbon steels, but this also makes them more difficult to work with. Machinability ratings are based on the carbon content of a particular grade. Steels that contain 0.2% or less carbon will tear when cut, while those containing more than 0.2% will get increasingly hard and become tough to machine.
High-carbon steels can be tempered to achieve different degrees of hardness and toughness, depending on the final use. Soft tempered steel is ideal for applications that require moderate forming, while hard tempered steel is suitable for flat-formed products such as clips, bolts, brake discs and clutches.
Carbon steels can also be alloyed with other elements such as nickel, molybdenum, chromium and vanadium to improve their properties. Alloyed carbon steels are more expensive than unalloyed high-carbon grades, but they can provide improved strength, hardness and wear resistance. They also have greater corrosion resistance than unalloyed steels.
Heat Treatment
Cold rolled high carbon steel spring steel strip is usually subjected to the heat treatment process of hardening and tempering, also known as H & T. This is a thermal process that involves heating the metal above its critical transformation temperature and then rapidly cooling it through quenching. This improves the mechanical properties of the steel and makes it tougher.
Depending on the desired characteristics of the final product, the heat treatment process can be Cold rolled high carbon steel spring steel strip manipulated to achieve different results. For example, if the strip is to be used for automotive applications, it can be made harder and stronger by increasing its carbon content or adding alloy elements.
The annealed steel is typically free of pearlite, while the spheroidized tempered strip may contain vestiges of pearlite. The material is mainly made of Si-Mn alloys and contains boron for enhanced hardenability. This type of steel has good workability and can be used in a wide range of applications, including springs, automobile components and lock parts. It is incredibly durable and is resistant to corrosion. It is also extremely versatile and pliable.
Good Elasticity
Spring steel has excellent elasticity, allowing it to return to its original shape after deformation. This can help reduce fatigue and corrosion. In addition, this metal is also resistant to stress cracking and has a high yield strength. This makes it ideal for creating reliable springs that can withstand high dynamic loads, such as those found in aircraft components and automotive disc brakes.
Depending on the grade of Tinplate Sheet supplier spring steel you choose, heat treatment processes may be used to enhance its hardness and durability. For example, some grades are hardened by quenching and tempering to provide superior resilience.
Alternatively, you can choose a grade such as 301 stainless that has been pre-tempered for added reliability and ease of fabrication. This can be particularly useful if you’re producing springs that are subject to continuous loading, such as the constant force springs found in hoover cables and seat belts. It also allows you to avoid the expense and inconvenience of additional heat treatments after cold forming. It can also be used to create springs for applications requiring high tensile strengths.
High Tensile Strength
Spring steel is pliable and resilient, which makes it easy to work with. It can withstand twisting and bending without becoming distorted, which makes it useful for springs, washers, lock picks, saw blades, vehicle coil springs, and other general uses. Its strength is derived from alloy elements that increase its hardness and ductility.
This material can be cold rolled to a range of widths and thicknesses. It can also undergo further cold reduction and annealing to achieve the desired properties. The strip can then be coiled or oscillate coiled for delivery and interleaved with paper or other material to prevent rusting.
This material is available in different tempers including spheroidized annealed, soft annealed, intermediate hardness, and full hard. It may be oiled or dry, as specified by the buyer. Its tensile strength is determined by placing it in a testing machine and measuring the force required to deform it. The results are plotted to create a stress-strain curve. This information can be used to design the best materials for various applications. Use the chart in Figure 4.5 as a guide to determine which materials are good for making springs and pivots.
Rounded Edges
Rounded edges can enhance a spring steel strip’s safety, especially for workers who handle the material. They also improve its performance by eliminating stress concentrations at sharp corners, which could lead to failure. Rounded edges can also reduce the risk of cuts or other injuries during handling.
The spring steel strip can be purchased in an annealed condition for hardening after forming or in the hardened and tempered state. It is important to understand the difference between these conditions to determine which one will be most suitable for your application.
The hardened and tempered medium & high carbon steel strip is available in a number of grades and thicknesses. It is a premium quality product that combines good spring properties with excellent toughness and tensile strength. It is suitable for use in a variety of industrial applications. The material is easily machinable and can be cut to a precise size using standard cutting tools. It can be delivered in a variety of finishes, including furnace blue-grey or bright ground finish. It is produced to international standards and can be supplied with rounded edges on request.
