• 304 is a kind of universal stainless steel, which is widely used to make equipment and parts with good comprehensive performance (corrosion resistance and formability).
• 301 stainless steel presents obvious work hardening phenomenon during deformation, which is used in various occasions requiring higher strength.
• 302 stainless steel is essentially a variety of 304 stainless steel with higher carbon content, which can obtain higher strength by cold rolling.
• 302B is a kind of stainless steel with high silicon content, which has high oxidation resistance at high temperature.
• 303se and 303se are free cutting stainless steels containing sulfur and selenium respectively, which are mainly used in the occasions requiring easy cutting and high surface finish. 303se stainless steel is also used to make machine parts requiring hot upsetting because it has good hot workability under such conditions.
• 304L is a variant of 304 stainless steel with low carbon content, which is used for welding. The lower carbon content makes the carbides precipitated in the heat affected zone near the weld to a minimum, and the precipitation of carbides may cause intergranular corrosion (welding corrosion) of stainless steel in some environments.
• 304n is a kind of stainless-steel containing nitrogen. The purpose of adding nitrogen is to improve the strength of steel.
• 305 and 384 stainless steels contain high nickel, and their work hardening rate is low, so they are suitable for various occasions with high requirements for cold formability.
• 308 stainless steel is used for welding rod.
• The contents of Ni and Cr in 309, 310, 314 and 330 stainless steels are relatively high in order to improve the oxidation resistance and creep strength of the steels at high temperature. However, 309S and 310S are variants of 309 and 310 stainless steels, but the difference is that the carbon content is low, so as to minimize the carbide precipitated near the weld. 330 stainless steel has high carburizing resistance and thermal shock resistance
• Type 316 and 317 stainless steels contain molybdenum, so their pitting corrosion resistance in marine and chemical industry environments is much better than that of 304 stainless steel. Among them, type 316 stainless steel includes low carbon stainless steel 316L and high strength stainless steel containing nitrogen.
• 316N and 316F, a free cutting stainless steel with high sulfur content.
• 321, 347 and 348 are stainless steels stabilized with titanium, niobium plus tantalum and niobium respectively. They are suitable for welding at high temperature. 348 is a kind of stainless steel which is suitable for nuclear power industry.
• The forging property of 304L stainless steel is poor and the deformation is difficult.

Scale or slag that varieties from welding processes is removed with a stainless steel wire brush. Normal carbon steel wire brushes will leave carbon metal particles within the surface which is able to ultimately produce surface rusting. For extra extreme purposes, welded areas should be treated with a descaling answer such as a mix of nitric and hydrofluoric acids, and these must be subsequently washed off.

Stainless Steel 904L Plates has Good resistance to pitting and crevice corrosion, superb resistance to stress corrosion cracking, good resistance to intergranular corrosion, good formability and weldability, maximum service temperatures of 450 degree C . The greater chromium, molybdenum and nitrogen content of 317LMN improve its capacity to resist pitting and crevice corrosion within the presence of chlorides and other halides. The Pitting Resistance Equivalent together with Nitrogen quantity is a relative measure of pitting resistance. The following chart provides a comparison Alloy 317LMN and different austenitic stainless steels. Alloy 304/304L (UNS S30400/S30403) is the most broadly utilized “18-eight” chromium-nickel austenitic stainless steel. It is an economical and versatile corrosion resistant alloy appropriate for a wide range of general function applications.
