Steelmaking begins with the smelting of iron ore, which then removes impurities such as phosphorus, silica and sulfur.
In the ore form, the concentration of carbon exceeds the level required for the unique properties of the steel. Therefore, steelmakers reprocess the molten metal to reduce the carbon content to the desired amount.
Stainless steel 304 flanges are a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also facilitates cleaning, inspection or modification. Stainless steel 304 flanges are made from the 18/8 chrome-nickel austenitic stainless steel alloy most used in stainless steel applications.
Flanges are usually welded or threaded. Flange joints are made by bolting two flanges together with a gasket between them to provide a seal.
Grade 304 stainless steel is the standard “18/8” stainless steel; it is the most versatile and widely used stainless steel available in a wider range of products, forms and finishes than any other.
Our stainless steel 316 socket weld flanges can be easily welded and machined through standard shop fabrication practices.
Our stainless steel 316 socket weld flanges can be easily welded and machined through standard shop fabrication practices. For most hot working processes, these stainless steel 316L lap joint flanges are recommended for forming at 1700¡ãF – 2200¡ãF (927¡ã – 1204¡ãC) Our stainless steel 316 ring joint style flanges are very ductile and easy to Forming, work hardening occurs during deformation, and chip breaking is easy.
Cold working operations will increase the strength and hardness of these stainless steel 316L eyeglass blind flanges and may make them slightly magnetic. Flanges are usually welded or threaded. Flange joints are made by bolting two flanges together with a gasket between them to provide a seal.
Stainless steel 316 flanges are composed of a chrome-nickel-molybdenum alloy and are typically used in conditions prone to chloride ion corrosion. The addition of molybdenum makes the material resistant to corrosion, especially in chloride-rich environments. 316L stainless steel flanges are the standard molybdenum grade, second only to 304 in austenitic stainless steels.
316l has excellent forming and welding characteristics. It is easily braked or rolled into various parts for use in industry, construction and transportation.
Flanges made of stainless steel are called “stainless steel 304 flanges”, also referred to as “SS 304 flanges”. Common material standards and grades include ASTM A182 Grade F304/L and F316/L, with pressure ratings of 150 to 2500 and 300 to 600, respectively.
SS 316/316L flanges can be fabricated from ASTM A182 F316 or F316L forgings, ASTM A351 CF8M or CF3M castings, and ASTM A240 316 or 316L plates per ASME B16.5 and ASME B16.47.
SS 316/ 316L flanges are available in many types such as butt weld, socket, blind hole, socket weld, lap, thread and reducer.
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.
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.
