stainless steel plate 304

stainless steel plate 304

All metals and oxygen react in the atmosphere,and then the surface formed oxide film. Unfortunately,iron oxide in the general carbon steel continues to oxidate,makes the rust expanding, and ultimately leads the formation of holes.You can use paint or oxidation-resistant metals (eg, zinc, nickel and chromium) plating to protect the steel surface,but, as people know, this protection is only a film. If the protective layer is damaged, the steel began to rust. Chromium is the basic elements to obtain corrosion resistance of stainless steel.When the steel contains about 12% chromium, the chromium and oxygen of corrosive media reacts thus forming a thin oxide film (from the passive film)in the steel surface,which can prevent further corrosion of the steel substrate. In addition to chromium,there are common alloying elements of nickel, molybdenum, titanium,niobium, copper, nitrogen, etc., to meet a variety of uses and properties of stainless steel requirements.

The four major classes of stainless steel plate
1.Ferritic: Chromium-iron alloys with 12-30% chromium.Its corrosion resistance,toughness and weldability improve with the increase of chromium content , and the resistance to chloride stress corrosion is better than other types of stainless steel. 

2.Austenitic: Chromium-nickel-iron alloys with more than 18% chromium, 8% nickel (Ni),very little Molybdenum, titanium, nitrogen, if any. Good overall performance,   makes it resist corrosion from variety of media.

3.Duplex: Two-phase alloys based on the Fe-Cr-Ni system. It owns  advantages
both in austenitic and ferritic stainless steel,with superplasticity.

4.Martensitic: Chromium-iron alloys with 10.5-17% chromium. High strength,poor ductility and weldability.
