ASTM A240 304 304L Plates

Grade 202 304 304L 316 316L 2B Finish Stainless Steel Sheet is a type of Cr-Ni-Mn stainless with similar properties to A240/SUS 302 stainless steel. The toughness of grade 202 at low temperatures is excellent.

ASTM A240 304 / 304L dual

ASTM A240 304 / 304L dual

ASTM A240 304 / 304L dual plate — S30400 / S30403

If the PO says ASTM A240 and grade 304 / 304L dual, you are in the right place. We supply that chemistry as sheet, plate and coil — this page focuses on plate.

Plain grade hub (non-ASTM URL): 304 / 304L dual flats. Category map: sheet & plate hub · ASTM A240 multi-grade.

In plain terms

Dual-certified 304 / 304L meets both ASTM A240 types — useful when the PO might call either grade.

When it makes sense

Use dual when either mark is acceptable. Single grades: 304 · 304L.

How to order without back-and-forth

Possible Alternative Grades

Possible alternative grades to grade 304 stainless steels are given in table 5.

Possible alternative grades to 304/304l grade stainless steel

Grade Why it might be chosen instead of 304
301L A higher work hardening rate grade is required for certain roll formed or stretch formed components.
302HQ Lower work hardening rate is needed for cold forging of screws, bolts and rivets.
303 Higher machinability needed, and the lower corrosion resistance, formability and weldability are acceptable.
316 Higher resistance to pitting and crevice corrosion is required, in chloride environments
321 Better resistance to temperatures of around 600-90°C is needed…321 has higher hot strength.
3CR12 A lower cost is required, and the reduced corrosion resistance and resulting discolouration are acceptable.
430 A lower cost is required, and the reduced corrosion resistance and fabricantion characteristics are acceptable.
