Why to pay extra if you have choice to get exact sizes and wall thickness in DIN 1.4539 schedule 40 Rectangular and Square pipe

Alloy 904L is the most resistant stainless steel, even though most of them show resistance to sulfuric acid in a range of concentrations. So, for applications that specifically use sulfuric acid or in those where sulfuric acid is a byproduct, the majority of manufacturers advise using grade 904L stainless steel seamless pipe. Sulfuric acid is a highly corrosive fluid that dissolves things at greater concentrations. Therefore, employing STM B673 UNS N08904 ERW Pipe, which is a robust material, is appropriate for these applications. Due to the addition of copper to the alloy, sulfuric acid resistance has been identified as a contributing factor.

Copper is the material of choice for engineering because it makes UNS N08904 schedule 40 pipe resistant to the sodium chloride found in marine conditions. Because of its abilities to resist corrosion, the ASTM A312 tp 904L material is classified as a super austenitic stainless steel alloy. The ASME SB677 TP 904L Square Pipe offers superior resistance to localised attack, especially from corrosion forms like pitting and crevice corrosion, because the alloy has a larger amount of molybdenum in its composition. Contrary to the more robust grade of stainless steel 904L seamless pipe, traditional alloys are more susceptible to pitting and crevice corrosion when chlorides and some reductive acids are present.

Due to the alloy's improved weldability and lower carbon content, ASTM A312 tp 904L Welded Pipe production is simplified. Due to the decreased carbon content, the formation of carbide precipitates on the DIN 1.4539 Rectangular Pipe is discouraged, preventing welding issues like intergranular corrosion.
