ASME B16.5 flanges are available in sizes 1/2″ to 24″ in classes 150, 300, 400, 600, 900, 1500, 2500.
ASME B16.47 Series A flanges are available in sizes 26″ to 60″ in 150, 300, 400, 600, 900 classes; while ASME B16.47 Series B flanges are available in 75, 150, 300, 400, 26″ to 60 sizes in 600, 900 grades.
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.
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.
