ASTM B677 TP 904L Stainless Steel Pipes, ASME SA 312 904L Stainless Steel Pipes, Stainless Steel 904L Seamless Pipes, Stainless Steel 904L Pipes, SS TP 904L Welded Pipes, 904L Stainless Steel Pipe, 904L SS PipesManufacturer in China.

Grade 904L SS is actually a non-stabilized austenitic SS that is having low carbon content. The ASTM B677 TP 904L Stainless Steel Pipe is having stainless steel that is added with the copper for the improvement of resistance against strong reducing acid like sulphuric acid. The UNS NO8904 steel is excellently resistant against stress corrosion cracking as well as crevice corrosion. ASME SA 312 904L Stainless Steel Pipe is also a non-magnetic and is offering the toughness, weldability, and formability.

TP 904L Welded Pipes 904L Stainless Steel Pipe

This grade is having a high amount of expensive ingredients like nickel and molybdenum alloy. Today most of the applications are demanding for this grade and is replaced by another alloy. This grade product is available in SS904L pipes forms. Austenitic stainless steel grade 904L is designed to achieve moderate to high corrosion resistance. This is due to the high amount of molybdenum, chromium and nickel content. The resistance properties of grade 904L stainless steel pipes include good resistance to stress corrosion cracking, and pitting and crevice corrosion, as well as inter granular corrosion.

 

SS 904L Seamless Pipe is also non-magnetic in all conditions, and has excellent machinability and weldability. Moreover, the austenitic structure gives it excellent toughness, even at cryogenic temperatures. 904L stainless steel pipe is suitable for various concentrations of sulfuric acid below 70¡æ. It is resistant to acetic acid of any concentration and temperature under normal pressure, and the corrosion resistance in the mixed acid of formic acid and acetic acid is also very good.
