Why 301 Stainless Steel Strip For Springs

The 301 stainless steel strip has high strength after cold working, which is the first choice for constant force springs manufacturing.

The constant force spring, also known as torsion spring, which is made of 301 stainless steel strip.

The stress can determine the spring diameter, strength and working life.

The action of a constant force spring is similar to the move of stretching a ribbon.

When the spring stretches and rewinds, the working part is tangent to the circle of the spring itself.

As long as the diameter of the spring is constant, the force of the spring is constant.

In an extremely long spring design work, the diameter has an advantage, and the tension increases slightly as the spring stretches.

However, this increased part is relatively small relative to the stretched length and can be ignored in many real life applications.

According to the application principle of them, constant force springs can be divided into linear motion constant type and rotary motion constant torque type.

When linear stretched, the unit of force will be kilogram, N, pound.

Constant force springs can be used for vehicles, automotive industry, counterweights, power sources, power cords, cordless curtains, generator radios and some toys.

Austenitic stainless steel strip for springs mainly includes SUS301-CSP and SUS304-CSP.

Compared with 304 stainless steel strip, SUS301 spring steel strip has a slightly lower corrosion resistance, but it is more suitable for spring production with a lower cost.

The spring tempered 301 stainless steel strip is a versatile metal that can be used in many applications where other metals are not suitable due to some limitation.

What is Spring Tempered 301 Stainless Steel Strip

Spring tempered 301 stainless steel strip is commonly used for springs manufacturing.

To make tempered stainless steel spring 301 strip, the cold rolled stainless steel is heated to a point just below its upper critical temperature, between 1700° F and 1850° F.

Then the material is rapidly quenched by immersion into liquid salt. The purpose of this rapid quenching is to trap carbon in solution, which causes the material to become austenitic.

After quenching, the material is then subjected to a second tempering treatment, where it is heated again to a temperature of about 1200° F. This second tempering relieves stresses developed during quenching, and also reduces the hardness of the material and makes it less brittle.

Spring tempered 301 stainless steel strip is made from grade 301 (S30100) stainless steel coil, which has a minimum of 16% chromium and 6% nickel.

It has been modified to increase both its strength and ductility. Other characteristics of this stainless steel grade are high strength, excellent corrosion resistance and the retention of a larger fraction of room temperature tensile strength than the common austenitic alloys like garde 304 stainless steel strip.

Spring tempered stainless steel strip is known for its ability to withstand high tensile stress and in turn helps minimize any permanent deformation.
