The austenitic stainless steel grade 904L is heavily alloyed, contains little carbon, and is not stabilized. The alloy of 904L Stainless Steel Pipe now contains copper. As a result, sulfuric acid is particularly resistant to powerful reducing acids. It is simpler to manufacture the AISI 904L Welded Pipe in accordance with ASTM A312 specifications because of the decreased carbon content. These pipes can be utilized for high-temperature applications despite having less carbon.
The ASME SA 312 TP904L alloy's significant nickel content gives the tube remarkable performance even in overground applications. The Stainless Steel 904L pipe demonstrates good resistance to stress-related corrosion cracking in addition to being a non-magnetic alloy.
The likelihood of crack corrosion is decreased by the presence of molybdenum in the alloy. ASTM A312 TP904L is primarily beneficial for general corrosive applications, in addition, to use in conditions at high temperatures.
mechanical testing such as flatness tests, shear load tests, and longitudinal load tests. To ascertain whether the 904L seamless pipe complied with the tensile qualities, tests were conducted on it.
Every 904L Pipe must be provided in a heat-treated state in accordance with ASTM A312 with the appropriate heat treatment temperature and justification for cooling or testing.
Features of Stainless Steel 904L
- Compared to stainless steels made of chrome-nickel, stainless steel 904l has superior corrosion resistance.
- Defends against attack from acetic, phosphoric, and sulfuric acids
- Excellent resistance to pitting under chloride-based circumstances
- controlled cracking and crevice attack due to stress corrosion.
Application of Stainless Steel 904LStainless Steel
- Scrubbers for coal-fired power plants using SAE 904L tubes for air pollution control.
- The major application for UNS N08904 tubes is in seawater cooling equipment.
- You can wire electrostatic precipitators using SS 904L tubes.
- The components of an oil refinery employ WNR 1.4539 tubes.
- Gas scrubbing plants can also benefit from AISI 904L tubes.
