- Areas of Usage: Often used in environments where the level of corrosion is high, i.e. a sulphuric acid plant, chemical processing line, offshore piping, and marine fluid systems.
- Material Integrity: Made of high-alloy stainless steel with increased levels of nickel and molybdenum, which has excellent resistance to pitting, crevice corrosion and stress corrosion cracking.
- Grade Specification: Made in Grade Stainless Steel 904L, meeting the ASTM A182 and the ASME criteria, and thus suitable with extreme temperatures and in a harsh environment with aggressive media.
- Other Characteristics: Works with both high temperature and low temperature environments and has good mechanical stability and sealing capabilities in a challenging industrial environment.

Stainless Steel 904L flanges are utilized in harsh service environments where acid, chloride and stress corrosion crack resistance is very essential. The nickel and molybdenum make the content high guaranteeing stability in the chemical processing, offshore, and pollution-control system. Stainless Steel 431 Flanges can also be considered and reconsidered during material evaluation as higher strength requirements are occasionally required, although 904L is used in more corrosive provided environments. On a B2B portal, tables that have details on standards, pressure ratings, and sizes assist the engineers and buyers to choose the right flange that will ensure longevity and compatibility with the system.
