Priminox Overseas is a known manufacturer of SS 304 / 304L / 304H Flanges, which has excellent forming and welding properties. Slip On Flanges is subject to pitting and crevice corrosion in warm chloride environments and to stress corrosion cracking above about 60 Degree C. The balanced austenitic structure of Blind Spectacle Flanges enables it to be severely deep drawn without intermediate annealing. This has made Alloy Weld Neck Flanges dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. Grade 304L Lap Joint is a sought after material for use in severely corrosive conditions, and also weld annealing is only necessary in applications where stress loads are excessive. Type 304L Orifice Flanges is used in a wide variety of home and commercial applications.

304L Flanges is therefore used in food processing equipment, particularly in beer brewing, milk processing, and wine making. Some examples of applications that AISI Slip On Flanges is commonly used for includes: Heat exchangers, Boilers, Condensers, and also it is most commonly used in petroleum refineries. Benefits of using Blind Spectacle Flanges include: Higher tensile yield strength and Greater short and long term creep strength. The carbon content of Weld Neck Flanges is controlled in the range of 0.04 % - 0.10 % for increased strength at temperatures above 800 Degree F (427 Degree C).
