ASTM A240 321 Stainless Steel Plate - SHH STEEL

ASTM A240 / ASME SA240 Type 321 Stainless Steel Plate (UNS S32100) -
China Mill-Direct Supply

1. Product Introduction
SHH STEEL (Shanghai Shenghonghe Import & Export Co., Ltd.) supplies
ASTM A240 / ASME SA240 Type 321 Stainless Steel Plate. ASTM A240 Type
321 is a titanium-stabilized austenitic chromium-nickel stainless
steel offering excellent intergranular corrosion resistance and good
high-temperature performance. Titanium combines preferentially with
carbon to form stable titanium carbides, preventing chromium carbide
precipitation at grain boundaries when the steel is exposed to the
sensitisation range (roughly 425-815 C) during welding or in service.
This makes 321 well suited to equipment operating intermittently or
continuously at elevated temperatures, where it also provides good
oxidation resistance and creep strength. It has good formability and
weldability, is non-magnetic in the annealed condition, and is
delivered solution annealed. Typical applications include aerospace
and automotive (including exhaust systems), chemical and
petrochemical plants, power generation, heat treatment equipment,
pressure vessels, refineries and general fabrication. 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 S32100 / EN
1.4541 / JIS SUS321 / GB 06Cr18Ni11Ti. 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 321; other related A240 plate grades are available on request.

4. Thickness, Width and Length Range
Thickness: 1 mm - 100 mm (thicker available). Size: width up to 2000-
3000 mm; lengths cut to order.

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. Hot rolled (No.1, heavy plate) and cold rolled
(2B/BA, sheet).

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.
