Seamless steel pipe network: 3042B stainless steel
304 is a material, 2B is cold-rolled, 304 is used for corrosion resistance, strong anti-oxidation ability, 8% nickel (1) 304 is a versatile stainless steel, it is widely used to produce a good overall performance requirements ( Corrosion resistance and formability of equipment and parts.
(2) 301 stainless steel exhibits a significant work hardening phenomenon during deformation and is used in various applications where higher strength is required.
(3) 302 stainless steel is essentially a variant of 304 stainless steel with a higher carbon content, which can be obtained by cold rolling.
(4) 302B is a kind of stainless steel with high silicon content, it has high resistance to high temperature oxidation.
(5) 303 and 303Se are free-cutting stainless steels that contain sulfur and selenium, respectively, and are used in applications where high lightness and high lightness are chiefly required. 303Se stainless steel is also used to make parts that require hot boring because the stainless steel has good hot workability under these conditions.
(6) 304L is a variant of 304 stainless steel with a low carbon content and is used where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, and the precipitation of carbides may result in intergranular corrosion of the stainless steel in some environments (weld erosion).
(7) 304N is a nitrogen-containing stainless steel. Nitrogen is added to increase the strength of the steel.
(8) 305 and 384 stainless steels contain high nickel and have a low work-hardening rate. They are suitable for various occasions requiring high cold formability.
(9) 308 stainless steel is used to make the electrode.
