304 / 304L Stainless Steel Seamless Tubing
304 and 304L grades of austenitic stainless steel are the most versatile and commonly used stainless steels. 304 and 304L stainless steels are variations of the 18 percent chromium – 8 percent nickel austenitic alloy.They exhibit excellent corrosion resistance to a wide range of corrosive environments.
316 / 316L Stainless Steel Seamless Tubing
316/316L stainless steel is one of the more popular stainless alloys. Grades 316 and 316L stainless steel were developed to offer improved corrosion resistance compared to alloy 304/L. The increased performance of this austenitic chromium-nickel stainless steel makes it better suited for environments rich in salt air and chloride .Grade 316 is the standard molybdenum-bearing grade, second in overall volume production to 304 amongst the austenitic stainless steels

MP(Mechanical Polishing) Stainless Seamless Pipe
MP (Mechanical polishing): is commonly used for the oxidation layer, holes, and scratches on the surface of steel pipes. Its brightness and effect depend on the type of processing method. In addition, mechanical polishing, although beautiful, can also reduce corrosion resistance. Therefore, when used in corrosive environments, passivation treatment is required. Moreover, there are often polishing material residues on the surface of steel pipes.
