JIS G4313 Cold Rolled Stainless Steel Strip For Springs SUS301 SUS304 SUS631

 

Stainless spring steels are classified as austenitic stainless steel ( SUS301-CSP, SUS304-CSP ),

martensitic stainless steel ( SUS420J2-CSP)

and precipitation hardening stainless steel ( SUS631-CSP, SUS632J1-CSP ).

JIS G4313 cold rolled stainless steel strip for springs, precision strip, known as thin strip

Widths ranging from 3 mm to less than 640 mm.
Thicknesses ranging from 0.05 mm to 1.5 mm.

 

SUS301 stainless 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.

 

SUS304 stainless provides good corrosion resistance, and is the most widely used stainless spring steel strip.

 

SUS301 and SUS304 are both austenitic stainless steels, so there is very little difference in their outward

appearance. The difference between them lies in their chemical composition, particularly their carbon,

chromium, and nickel content. SUS301 stainless is 0.15C17Cr7Ni, while SUS304 stainless is 0.08C18Cr8Ni.

This difference actually affects the mechanical properties of the steel after rolling, for example,

SUS301 stainless can be made stronger than SUS304 stainless by rolling.

 SUS301 stainless is recommended for applications that require elasticity, due to its ability to acquire

a high degree of strength when rolled. 

SUS304 is recommended for applications that require good workability and corrosion resistance,

while SUS304L stainless is recommended for those that require resistance to intergranular attack. 

SUS304L stainless contains less carbon than SUS304 stainless. 

Its low carbon content gives it good resistance to intergranular corrosion, while its high nickel content gives

it excellent corrosion resistance. SUS304L stainless is easy to process because it does not become

excessively hard. (Note: The "L" in SUS304L stainless stands for "low carbon.")

 

SUS420J2 is classified as a martensitic stainless steel. Thanks to its marketability, price, and

other features, it is used in a wide range of fields. When shipped with an annealed finish,

it contains completely spheroidized carbides, making it easily processed.

 

SUS631 stainless is the most common precipitation hardening stainless steel that can be hardened

through heat treatment.

It can be subjected to a variety of heat treatment processes to suit working and applications from the

softest solution heat treatment to a hard full-hardened finish.

This allows it to acquire strength second only to quenched high-carbon martensitic stainless steels.

In a solution-heat-treated state, SUS631 is non-magnetic, but demonstrates quite strong magnetic properties

after precipitation hardening.

 

Although SUS631 becomes soft and can be processed in a variety of ways when solution heat treated,

it requires an intermediate heat treatment to harden. Even when solution heat treated,

SUS632J1 ( 15-7PH ) is hard at normal temperature, and the only heat treatment subsequently required is a

single precipitation hardening operation, which makes it simple to process.

It has a low carbon content and provides toughness after solution heat treatment, so it can withstand light processing.

SUS632J1 can be finished as solution heat treated or as rolled. When produced with an as rolled finish,

it can acquire greater strength, but is not as strong as SUS631. It demonstrates strong magnetic properties in all conditions.
