ASTM A240 304L Stainless Steel Plate - SHH STEEL

ASTM A240 / ASME SA240 Type 304L Stainless Steel Plate and Sheet (UNS
S30403)

1. Product Introduction
SHH STEEL (Shanghai Shenghonghe Import & Export Co., Ltd.) supplies
ASTM A240 / ASME SA240 Type 304L Stainless Steel Plate and Sheet.
ASTM A240 Type 304L, also known as SS304L, UNS S30403 or SUS304L, is
the low-carbon version of Type 304, designed under the ASTM A240 /
ASME SA240 specification to provide superior resistance to
intergranular corrosion after welding. The maximum carbon content of
0.03% significantly reduces the risk of carbide precipitation during
welding, making 304L the preferred choice for welded pressure
vessels, tanks and process equipment in corrosive environments. Like
304, it is an 18% chromium / 8% nickel class austenitic stainless
steel with excellent formability, good toughness at low temperatures
and a non-magnetic structure in the annealed condition. Heavy
sections can usually be welded without post-weld annealing, which
saves fabrication time and cost. Typical applications include welded
pressure vessels, storage tanks, process equipment, chemical and food
processing plants, piping fabrication and general welded structures.
Available surface finishes include No.1, 2B, 2D, BA, No.4, HL
(Hairline) and 8K Mirror; protective PVC film can be applied on one
or both sides for architectural or specific functional requirements.
Product forms available include plate, sheet, coil, strip, foil,
shim, circle and ring.

2. Standards We Can Supply
ASTM A240 / ASME SA-240 (full compliance). Dimensional tolerances and
flatness follow ASTM A480; equivalent designations: UNS S30403 / EN
1.4306 / JIS SUS 304L / GB 022Cr19Ni10. Material can also be offered
against equivalent EN, JIS and GB designations listed above.

3. Grades We Can Supply
Austenitic: 304, 304L, 304H, 304N, 304LN, 316, 316L, 321, 310S.
Duplex: 2205 (UNS S32205 / S31803). Ferritic: 430. This offer focuses
on 304L; other related A240 plate grades are available on request.

4. Thickness, Width and Length Range
Thickness: 0.3 mm - 100 mm. Size: width up to 2500 mm and length up
to 12000 mm; custom sizes are available on request.

5. Processing
Steel cutting services (shearing, precision plasma, laser or waterjet
cutting), slitting, leveling and cut-to-length, steel bending and
forming, steel welding, CNC steel machining and stainless surface
finishing / polishing (No.4, HL, 8K mirror). Edge conditions include
mill edge, slit edge, sheared edge or plasma/laser cut edge according
to customer preference. Width tolerance is typically +6 mm / 0 mm and
length tolerance for cut-to-length material is normally +10 mm / 0
mm; improved flatness and tighter tolerances can be arranged for
precision fabrication.

6. Delivery Time
Stock material: 5-6 days. Normal production orders: 30-40 days.

7. Payment Terms
T/T and L/C accepted; specific payment terms are negotiated per
order.

8. Trade Terms
FOB / CIF / CFR.

9. Delivery Condition
Hot rolled (No.1, heavy plate) and cold rolled (2B/BA, sheet),
supplied in the annealed condition.

10. Quality Assurance
Mill test certificate supplied with every shipment (global export
with full MTCs). Chemical composition and mechanical properties
conform to ASTM A240 / ASME SA-240.
