Sulfuric acid is a highly corrosive acid and is used in several industries including chemical processing, dyeing, textiles, etc. Withstanding sulfuric acid is a difficult task, especially since metals undergo rapid degeneration. Therefore, the development of 904l Stainless Steel Seamless Tubing material is integral for the sustenance of these applications. Because sulfuric acid is a very strong acid, it takes a durable material like a super austenitic stainless steel to survive in these applications.

SS 904L Cold Rolled Coiled Tubing is called a super austenitic stainless steel alloy because it has a high PREN value, particularly compared to other conventional stainless steel alloys including grade 304 and grade 316. The pitting resistance equivalent number of WERKSTOFF NR.1.4539 Heat exchanger Tube is valued at more than 37. Furthermore, many buyers prefer the use of this material because the ASTM A213 TP 904L Instrumentation Tubes outperform both grade 304 and grade 316 in environments that are conducive to stress related corrosion cracking.

The high content of both nickel and molybdenum in the alloy increases the ability of the ASTM A249 TP 904L Welded Tube to withstand chloride ion induced stress corrosion cracking. Generally, chloride ions have an adverse effect on the more traditional stainless steel alloys. Though both welded and seamless tubes in this alloy are durable, the 904L Stainless Steel Seamless Tube can bear pressure that is almost 20% more than the welded kind. However, one has to understand that the cost of producing a seamless UNS N08904 EFW Tube is more than the welded kind.
