To keep track of the distinguishing characteristics of steel, manufacturers have created a naming system that is both systematic and exhaustive.
Because of its corrosion-resistant properties, Type 316 stainless steel is often used in engineering applications, especially in construction and manufacturing.
The alloy is resistant to chloride stress-corrosion cracking and pitting.
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.
UNS We offer different kinds of 304 SS flanges such as SS 304 Reducer Flange, SS 304 Slip Flange, SS 304 Orifice Flange, SS 304 Nipo-Flange, SS 304 Lose Flange, SS 304 Lap-Joint Flange and SS 304 Blind flange. We conduct thorough quality checks on our products to ensure their durability and reliability.
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.
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.
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.
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.
With the addition of nitrogen as a strengthening agent, the alloy can be dual certified as Alloy 317 (UNS S31700).
Alloy 317L is non-magnetic in the annealed condition.
It cannot be hardened by heat treatment;?however?the material will harden due to cold working.
Alloy 317L can be easily welded and processed by standard shop fabrication practices.?
The higher molybdenum content of Alloy 317L assures superior general and localized corrosion resistance in most media when compared with 304/304L and 316/316L stainless steels.
Environments that don¡¯t attack 304/304L stainless steel will normally not corrode 317L.
One exception, however, are strongly oxidizing acids such as nitric acid. Alloys that contain molybdenum generally do not perform as well in these environments.?
Alloy 317L has excellent corrosion resistance in a wide range of chemicals. It resists attack in sulfuric acid, acidic chlorine and phosphoric acid.
AL6XN has greater tensile strength than common austentitic stainlesses, while retaining high ductility and impact strength.
