Product Description

201 304 316 309 310 321 Polished Surface cold rolled stainless steel sheet

300 Series stainless steels are classified as austenitic, and are hardenable only by cold working methods. These grades of stainless have chromium (approx. 18 to 30%) and nickel (approx. 6 to 20%) as their major alloying additions. Type 304 is the most widely used alloy of all stainless steels. 300 Series Stainless steel alloys resist corrosion, maintain their strength at high temperatures and are easy to maintain.

Does 321 stainless steel rust?
Type 321 has excellent intergranular corrosion resistance after exposure to this temperature range, and this grade resists oxidation up to 1500˚F and has higher creep and stress rupture properties than 304/304L. It also possesses good low temperature toughness and is non-magnetic in the annealed condition.

Is stainless steel 321 magnetic?

While corrosion resistance is similar to 304 and 304L in the annealed condition, it features higher creep and stress rupture properties, making it ideal for pressure vessels and boiler applications. 321 stainless steel is non-magnetic and heat resistant for continuous service at elevated temperatures.

a) 2B: The surface brightness and flatness of 2B is better than 2D.then through a special surface treatment to improve its mechanical properties, 2B could nearly satisfy comprehensive uses
b) NO.3: Polished with abrasive belt of git#100#200, have better brightness with discontinuous coarse stria, used as inner and external omaments for building, electrical appliances and kitchen utensils etc
c) NO.4: Polished with abrasive belt of grit#150#180,have better brightness with discontinuous
coarse stria, but thinner than NO.3, are used as bathtub buildings inner and extemal omaments electrical appliances kitchen utensils and food processing equipment etc
d) HL: Polished with abrasive belt of trit#150#320 on the NO.4 finish and has continuous streaks, mainly used as buildings omaments elevators, door of building, frontal plate etc

e) BA: Cold rolled, bright annealed and skin-passed, the product have excellent brightness and food reflexivity like mirrorm kitchen apparatus, omament etc
f) 8K: The product have excellent brightness and prefer reflexivity can be the mirror



Architectural decoration, luxury doors, elevators decorating, metal tank shell, ship building,decorated inside the train, as well as outdoor works, advertising nameplate, the ceiling and cabinets, aisle panels, screen, the tunnel project, hotels, guest houses, entertainment place,kitchen equipment, light industrial and so on.
