Stainless Steel Coil and Slit Coil 304 / 430 - SHH STEEL

304 / 430 Stainless Steel Coil and Slit Coil (ASTM A240 / JIS G4305)

1. Product Introduction
SHH STEEL (Shanghai Shenghonghe Import & Export Co., Ltd.) supplies
304 / 430 Stainless Steel Coil and Slit Coil. SHH STEEL supplies 304
and 430 stainless steel in coil and slit coil (strip) form to ASTM
A240 and JIS G4305. Type 304 (UNS S30400 / SUS304) is the most widely
used austenitic stainless steel, containing approximately 18%
chromium and 8% nickel, with outstanding corrosion resistance,
formability, weldability and cost-effectiveness; it is non-magnetic
in the annealed condition and ideal for deep drawing. Type 430 (UNS
S43000 / SUS430) is the most popular ferritic stainless steel,
containing 16-18% chromium and low carbon. It provides good
resistance to atmospheric corrosion, fresh water, nitric acid, many
organic media and oxidation at elevated temperatures; it is magnetic,
has excellent formability and is more cost-effective than austenitic
grades such as 304. JIS G4305 is the Japanese standard for cold-
rolled stainless steel plates, sheets and strips, and both grades are
supplied cold rolled for coil products. Slit coils are produced from
master coils to the customer's required width with slit edges, ready
for stamping, roll forming, tube making and deep drawing lines.
Typical applications include kitchen equipment, home appliances,
architectural and decorative panels, automotive parts, food
processing and industrial equipment (430); food and beverage
equipment, chemical processing, construction, tanks and kitchen and
sanitary ware (304). Available surface finishes include 2B, 2D, BA,
No.4, HL (Hairline) and 8K Mirror for 430 cold-rolled coil; No.1, 2B,
BA and others for 304; 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), JIS G4305 (cold-rolled
plate, sheet and strip). Dimensional tolerances and flatness follow
ASTM A480; equivalent designations: 304: UNS S30400 / SUS304. 430:
UNS S43000 / EN 1.4016 (X6Cr17) / JIS SUS430 / GB 10Cr17. 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 304 and 430 coil; other related A240 plate grades are available on
request.

4. Thickness, Width and Length Range
Thickness: 430 cold-rolled: 0.3 mm - 3.0 mm (standard); 304: from 0.3
mm. Size: SUS430 cold-rolled product up to 1500 mm wide (ASTM A240
430 up to 1500-2500 mm); slit coil widths cut to customer
requirement; cut-to-length sheets can be supplied from coil.

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
Cold rolled and annealed (2B, BA and other finishes); hot rolled
annealed and pickled (No.1) also available for 304.

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.
