What are the requirements for ASTM A511 stainless steel seamless pipes?

　　ASTM A511 stainless steel seamless pipes Mechanical Tube manufacturer in China

　　ASTM A511 tubing is a specification for mechanical applications with high corrosion resistance. The ASTM A511 stainless steel pipe is seamless and has higher dimensional accuracy.

　　There are different grades of materials used in this range of tubes. There are also different types of tubing such as the ASTM A511 Seamless Stainless Steel Mechanical Tubing and Hollow Bar that are used in different applications.

　　The material grades range from MT 302, 303, 304, 305 to MT347. All these grades have manganese, phosphorus, sulfur, silicon, nickel and chromium in the composition.

　　Some of the ASTM A511 Seamless tube grades also have molybdenum, titanium and columbium in different quantities.

　　The grade MT303se has selenium in it. The ASTM A511 MT304 is the most used as it is cost efficient and has good strength and long lasting life. The corrosion resistance of the material is low compared to other grades such as the 316.

　　The ASTM A511 grade tubes can range in sizes from 1 ½ inches to 24 inches and above according to the custom requirements. The length of the tubes varies with specifications and applications types as well.

　　The ASTM A511 is a chromium nickel molybdenum austenitic stainless steel. It has higher corrosion resistance against chloride iron stress corrosion cracking. Therefore these tubes are preferred in marine, sea water, food processing, wastewater management, pollution control and in brackish water applications.
