Product Information
Stainless
steel SUS 304/304L is the standard
stainless steel that is commonly used and introduced in the different types of
products, forms and finishes. The balanced austenitic structure of steel 304
enables it to be fully deep drawn without intermediate annealing that has made
this alloy a prominent material in the production of drawn stainless parts such
as sinks, hollow ware and saucepans. For these applications, it is common to
use special grade variants.
SUS
304/304L is brake or roll produced in the different parts
for applications in the commercial, architectural and transportation fields.
The steel 304 offers excellent welding features, the post welding is not
necessary while welding thin regions.
The grade 304L, the low
carbon version of 304, does not need post weld annealing and it is broadly used
in the heavy gauge parts. Steel 304H with its higher concentration of carbon is
useful in the elevated temperatures. The austenitic structure provides superior
toughness even at temperatures lower than cryogenic limits.

Possible Alternative Grades
|
Grade |
Reasons to replace SUS 304 |
|
301L |
When larger work hardening rate grade is needed
for fix roll formed or stretch formed parts. |
|
302HQ |
Lower work hardening rate is required for cold
forging of screws, bolts and rivets. |
|
303 |
Larger machinability is required and lesser
corrosion resistance, formability and weldability are adequate. |
|
316 |
Great resistance to pitting and crevice
corrosion is required in the chloride conditions |
|
321 |
Larger resistance to temperatures up to
600-900oC is required. Alloy 321 has higher hot strength. |
|
3CR12 |
Affordable. The lower corrosion resistance
and resulting discolouration are acceptable. |
|
430 |
Affordable and the lower corrosion
resistance and fabrication properties are acceptable. |
Corrosion Resistance
SUS 304 offers outstanding
resistance in the various natural conditions and corrosive conditions. It
performs well in the pitting and crevice corrosion conditions in the hot
chlorides and stress corrosion cracking up to 60oC. It offers resistance to
potable water about 200mg/L chlorides at ambient temperatures, decreasing to
150 mg/L at 60oC.
