What Is The Difference Between A Stainless Steel Wire And A Spring Steel Wire?

The strength of carbon spring steel wire can reach 2000-2500mpa, which can be used as spring, and can also be used to make manganese phosphating coated steel wire rope and so on.Stainless steel wire strength is generally 1200-1500MPA, strength is much lower than carbon steel wire, but stainless steel wire anti-corrosion performance is excellent.

The spring is used in the elastic range. After unloading, the spring should be returned to its original position. The smaller the plastic deformation, the better. Therefore, the steel wire should have high elastic limit, yield strength and tensile strength.

The higher the ratio is, the closer the elastic limit is to the tensile strength, and thus the higher the strength utilization, the stronger the spring force.

Spring, relying on elastic deformation to absorb impact energy, so the spring wire doesn't have to have very high plasticity, but there are at least able to withstand the spring forming of plastic, toughness and enough to withstand impact energy.

Spring is usually long work under alternating stress, so it has a high fatigue limit and good resistance to creep and relaxation.

The spring used in a particular environment will also have special requirements for the steel wire. For example, the spring used in the corrosive medium must have good corrosion resistance.

The spring used in precision instrument should have long-term stability and sensitivity, low temperature coefficient, high quality factor, small aftereffect, and constant elastic modulus.

The spring of working in high temperature condition is required to maintain sufficient elastic limit and good creep resistance at high temperature.
