1. Specifications about stainless steel sheet
309/309s,310/310s stainless steel sheet are high temperature resist
stainless steel.We hold about 5000-10000 Metric tons stainless
steel in stock monthly. we provide the best prices, quality,
support, and quick delivery time
Alloy 309/309S (UNS S30900/S30908) austenitic stainless steel is typically used for elevated
temperature applications. Its high chromium and nickel content
provides comparable corrosion resistance, superior resistance to
oxidation, and the retention of a larger fraction of room
temperature strength than the common austenitic Alloy 304.
Stainless steel 310/310S is an austenitic heat resistant alloy with excellent resistance to
oxidation under mildly cyclic conditions through 2000°F. Its high
chromium and nickel contents provide comparable corrosion
resistance, superior resistance to oxidation and the retention of a
larger fraction of room temperature strength than the common
austenitic alloys like Type 304. Stainless 310 is often used at
cryogenic temperatures, with excellent toughness to -450°F, and low
magnetic permeability.

3. Production Flow about stainless steel sheetRaw materials are sending to hot rolling units for rolling into
different sizesHot rolled material is annealing in cold rolled annealing furnace
and pickling in acid.All mill rolls are grinded on precision grinding machine with
proper chamfering after first shift operation.All sheets are pickled in different tanks and dried on brush roll
machine before dispatched.These sheets are again annealing and are sent to straighten machine
for straightening.Inspections are done at various stages. Keep proper control overall
internal process via rolling,annealing and pickling by our
experienced staff4.Surface--stainless steel sheet| Surface Finish | Definition | Application |
