Stainless Spring Steel Strip Grades
Stainless spring steel strips are available in various grades, each with its own unique properties and characteristics. The choice of grade depends on the specific requirements of the application, including factors like corrosion resistance, tensile strength, and elasticity.
Some common stainless spring steel strip grades include:
301 stainless steel strip: This grade is known for its excellent corrosion resistance and high tensile strength. It is often used for springs, washers, and clips in mildly corrosive environments.
17-4PH stainless steel strip: This is a precipitation-hardening stainless steel strip with a combination of high strength, good corrosion resistance, and ease of heat treatment. It is suitable for various spring and structural applications.

Stainless Spring Steel Strip: The Ultimate Guide
When you choose to buy quality stainless spring steel strip, there have some important points we need to know before we get started.
What are 301 stainless spring 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.
