Stainless steel 316/ 316L flanges can be made by hot forging or casting. Blind or sliding plate flanges without hubs can be machined directly from the plate. Flanges should be solution treated at not less than 1900¡ãF [1040¡ãC] and then quenched in cold water or other rapid cooling method.
These stainless steel 316L threaded flanges perform well in fresh water service even with high chloride levels.
In most cases, the corrosion resistance of our stainless steel 316 butt weld flanges is about the same in most corrosive environments.
In environments that are corrosive enough to cause intergranular corrosion in welds and heat affected zones, these should use stainless steel UNS S31600/S31603 blind flanges due to its low carbon content.
ASTM A182 F316L is a forging material specification for 316L grade stainless steel and is used for manufacturing bare forgings or forged and machined products for applications involving high temperature service.
