A flange is a ring of steel (forged, cut from plate, or rolled) designed to connect sections of pipe, or to join pipe to a pressure vessel, valve, pump or other integral flanged assembly. Flanges are joined to each other by bolts, and to the piping system by welding or threading (or loose when stub ends are used). Stainless steel flange simplified as SS flange, it refers to the flanges that made of stainless steel.

317L stainless steel fasteners are used in applications utilizing reclaimed water, such as power generation and pulp mill condensers. Other common uses are in the food and beverage industry.

?The low carbon content of Alloy 317L enables it to be welded without intergranular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition.

S31803 is the Unified Numbering System (UNS) designation for the original duplex stainless steel. The UNS system was created by multiple trade groups in the 1970s to reduce confusion when the same alloy was called different things, and vice versa. Each metal is represented by a letter followed by five numbers, where the letter represents the metal series, i.e. S for stainless steel.

For paper mill applications requiring lower alloy grades that do not have sufficient corrosion resistance. Based on a 22% chromium content, they have a combined austenitic:ferritic microstructure that provides greater strength, corrosion resistance and cost-effectiveness.

The UNS S31803 (ASTM F51) specification has been largely superseded by UNS S32205 (1.4462, ASTM F60). This reflects their desire to maximize the alloy’s corrosion properties, thanks to the development of the AOD steelmaking process, which allows for tighter control of composition. In addition, it allows to influence the nitrogen addition level rather than just being present as a background element. Therefore, the highest performing duplex grades seek to maximize the content of chromium (Cr), molybdenum (Mo) and nitrogen (N).

Applications for ASTM a276 Grade 304l round bars must be limited to those applications that require these bars to be joined by welding and do not require excellent tensile strength properties.

SS 316/316L/316Ti round bars/rods are made from chemical compositions such as carbon, nickel, copper, chromium, titanium, iron and manganese. These rods and rods are designed with physical and mechanical properties such as density, yield strength, tensile strength, elongation, thermal conductivity, electrical conductivity, modulus of expansion, and electrical expansion.

The combination of nickel and chromium in Incoloy 925 Ring Joint Type Flanges renders protection in both oxidizing and reducing atmospheres. High speed operations in Incoloy 925 Spacer Flanges such as grinding, milling or turning, are usually performed using water ¨C based coolants.

Environments that don¡¯t attack 304/304L stainless steel will normally not corrode 317L.

The lower carbon content of 304L alloy helps to minimize/eliminate carbide precipitation during welding. This allows 304L stainless steel to be used “as welded”, even in severely corrosive environments. If you use standard 304 stainless steel in the same way, it will degrade faster at welded joints.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

304 has good oxidation resistance in intermittent duty up to 870¡ãC and continuous duty up to 925¡ãC. However, continuous use at 425-860¡ãC is not recommended. In this case, 304L is recommended because of its resistance to carbide precipitation.

Stainless Steel 316 Flanges
Featuring 304 stainless steel for very good corrosion resistance, this GRAINGER APPROVED weld neck flange can be attached to a system via a circumferential weld at the neck. The welded area can be easily examined by radiography. Matched pipe and flange bore reduces turbulence and erosion inside the pipeline. Flange is excellent for use in your critical applications and is ideal for use with air, water, oil, natural gas, and steam.

316 / 316L Stainless Hex Socket Head Bolts are used in applications requiring high strength, toughness and machinability along with improved corrosion resistance. The alloy contains a higher percentage of molybdenum and nickel than grade 304 stainless steel, improving corrosion resistance, making it ideal for applications in corrosive environments. 316L stainless steel has a higher carbon content than 316 stainless steel, reducing its weldability.

All in all, if you need superior corrosion resistance and your application contains water, then 316 steel is worth it. If not, 304 steel will suit your needs well.

Hardness and tensile strength can be increased by cold working, but modified by lowered carbon content providing good resistance to corrosion in welded construction where subsequent heat treatment is not practical.

A flange is a ring of steel (forged, cut from plate, or rolled) designed to connect sections of pipe, or to join pipe to a pressure vessel, valve, pump or other integral flanged assembly. Flanges are joined to each other by bolts, and to the piping system by welding or threading (or loose when stub ends are used). Stainless steel flange simplified as SS flange, it refers to the flanges that made of stainless steel.

A403 316L Stainless Steel covers the standard for wrought austenitic stainless steel fittings for pressure piping applications.Compared to grade 316, the pitting resistance properties of ASME B16.9 SS 316L Fitting is much higher.

304 stainless steel elbow is a pipe fitting that connects two pipes with the same or different nominal diameters in the piping system, so that the pipes are bent at a certain angle. According to the angle, the most commonly used are 45¡ã, 90¡ã, 180¡ã. In addition, according to engineering needs, other abnormal angle elbows such as 60¡ã are also included. The connection methods with the pipeline include direct welding (the most common method), flange connection, threaded connection, socket connection, etc.

SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.[1]

Stainless Steel 304 Pipe Fittings are made from seamless steel pipes whereas ERW pipes are made from ERW steel pipes.

Molybdenum and nitrogen content significantly increased the resistance of pitting and crevice corrosion in the halide media. Meantime, nickel and nitrogen not only ensures the stability of metallographical, but also reduce separating intergranular trend in the thermal process or welding process better than the nitrogen content of nickel alloy.

UNS NO8904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate.
