ASTM A240 316L Stainless Steel Plate - SHH STEEL

ASTM A240 / ASME SA240 Type 316L Stainless Steel Plate and Sheet (UNS
S31603)

1. Product Introduction
SHH STEEL (Shanghai Shenghonghe Import & Export Co., Ltd.) supplies
ASTM A240 / ASME SA240 Type 316L Stainless Steel Plate and Sheet.
ASTM A240 Type 316L, also known as SS316L, UNS S31603 or SUS316L, is
the low-carbon version of Type 316 and is specifically designed for
welded constructions in corrosive environments. It is a molybdenum-
bearing austenitic chromium-nickel stainless steel containing 2.00-
3.00% molybdenum, which greatly improves resistance to pitting and
crevice corrosion in chloride-containing media compared with 304-
series grades. The low carbon content (0.030% max) minimises carbide
precipitation in the heat-affected zone, giving excellent resistance
to intergranular corrosion after welding. 316L can be welded by all
common fusion welding processes, including GTAW (TIG), GMAW (MIG),
SMAW and plasma welding, without post-weld annealing in most cases;
matching filler metals such as ER316L are recommended. In the
solution-annealed condition it combines good strength with excellent
ductility and toughness, with hardness of not more than 217 HB / 95
HRB and a density of 8.00 g/cm3. It is non-magnetic in the annealed
condition and keeps good toughness down to cryogenic temperatures.
Typical applications include chemical processing, marine and coastal
environments, the food and beverage industry, pharmaceutical and
biotech equipment, pulp and paper, architecture and construction, and
general industrial welded equipment such as tanks, pressure vessels
and piping systems. 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 S31603 / EN
1.4404 / JIS SUS 316L / GB 022Cr17Ni12Mo2. 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 316L; other related A240 plate grades are available on request.

4. Thickness, Width and Length Range
Thickness: 0.4 mm - 100 mm. Size: width up to 2500 mm and length up
to 12000 mm; custom sizes are available. By finish: 2B cold-rolled
sheet is typically supplied up to 1500-2000 mm wide depending on
thickness, and No.1 hot-rolled plate is typically 3.0-100 mm thick
(most common 4.0-50 mm) with maximum width up to 2000-2500 mm.

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
Solution annealed and pickled. 2B finish: cold rolled, annealed,
pickled and skin-passed. No.1 finish: hot rolled, annealed and
pickled, the standard finish for heavy plate.

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.
