Spring tempered 301 stainless steel strip is a high tensile grade of steel that maintains its strength and corrosion resistance even when subjected to the harshest conditions.
It is also known for its ability to retain its shape memory properties after being exposed to high temperatures.
The combination of these qualities makes stainless steel 301 spring tempered ideal for applications that require frequent or repeated exposure to extreme temperatures, as well as those which require an unusually high degree of precision.
This can heavily contribute towards the results that you will be able to get at the end of the day.

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.

Why are We Using 301 Stainless Steel in Springs?
Stainless steel springs are used in a variety of applications that require exposure to the elements and corrosive materials. Stainless steel springs are used for shock loads and high stresses associated with extreme temperatures, high pressures and corrosive environments.
Stainless steel is a great material for springs because it has high tensile strength, which means it can hold up to a lot of pressure without breaking. Another property that makes stainless steel ideal for springs is its corrosion resistance. This means that the spring can resist damage from moisture and harsh environments.
The best stainless steel for springs is alloy 301. This stainless steels are generally considered non-magnetic which makes them ideal for applications where rust, corrosion, and durability are important.
People use 301 stainless steel strip in our springs manufacturing because it is the most economical material that offers good corrosion resistance while maintaining the strength needed to withstand high temperatures, pressures and loads.
