Stainless Spring Steel EN 1.4310 ( SUS301 ) Cold Rolled Slit Strip / Precision Strip
Stainless spring steels are classified as austenitic stainless steel.
Due to their good balance of mechanical properties, they are the most widely used type of steel.
They can be used in a variety of environments without being plated to prevent rust.
In addition, as it is also possible to increase their hardness by rolling, they can be used as spring parts.
In annealed and lightly rolled materials, they exhibit a large degree of elongation, and can withstand complex processing.
What is SUS301?
SUS301 has a lower chromium and nickel content than SU304, which allows it to harden more when worked.
Its high hardness makes it ideal for applications that require durability such as coil springs and dome switches.
What is SUS304?
SUS304 provides good corrosion resistance, and is the most widely used stainless spring steel strip.
