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]

SMO 254 Hexagonal Pipes is subject to pitting and crevice corrosion in warm chloride environments and to stress corrosion cracking above about 60 Degree C.

Steel bars are one of the core components of any manufacturing
industry or for that matter any industry that relies on machineries.
Thanks to its versatile applications, steel bars find itself in the
epicenter of most of engineering industries, be it automotive, textile,
fabrication, construction, cement, ship building, paper and pulp,
defence, heavy earth moving equipments or aerospace.
The overwhelming popularity of steel bars is owed to the fact that
it is possible to be produced in varying types, shapes, sizes, and
grades of bars to cater the exact technical requirements. Steel
bars generally have the shapes such as flat, round, hexagonal,
square and channel and on most of the occasions, it is the shape
of the bar that defines its application area

Alloy 310S Seamless Pipes has oxidation resistance to 2000°F. ASME SA312 SS 310S Seamless Pipes has moderate strength at high temperature. UNS S31008 Seamless Pipes is quite resistance to hot corrosion. Also referred as WNR 1.4845 Seamless Pipes, it has strength and toughness at cryogenic temperatures. It is readily fabricated by standard commercial procedures. In comparison to carbon steel, these stainless steels are tougher and tend to work harden rapidly.

The addition of copper to this grade gives it better corrosion resistance than conventional chromium-nickel stainless steels, especially against sulfuric, phosphoric and acetic acids. However, the use of hydrochloric acid is limited.

Our SS 317 flanges are well received by customers for their reliable performance, durability and excellent resistance to corrosion and wear. SS 317 is a molybdenum-containing austenitic alloy with increased chemical resistance compared to general chromium-nickel alloys such as SS 304 and SS 316L.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

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 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.

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.

Stainless steel 304 is a type of stainless steel that is resistant to corrosion and rusting. Stainless Steel 304 Forged Fittings are used for connecting two pipes or tubes together and can be made from a variety of metals, including copper, brass, aluminum, or stainless steel.

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. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500. It used in more industries than carbon steel as stainless steel has better resistant performances on corrosion environment and always provides with a good appearance.

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]

Due to its thin chemical composition, RA 253 MA is very economical compared to most heat resistant alloys. Stainless steel 253 MA fasteners have equivalent grades such as UNS S30815, standard SS 253 MA and its WERKSTOFF NR. is 1.4835. The mechanical properties in the specified limit minimum are its 2″ elongation of 40%, its ultimate tensile strength of 87,000 psi, its area reduction of 50%, and its offset yield strength of 45,000 psi.

Austenitic Stainless steels like 316 and 304(those with high chromium and nickel contents) offer even more resistance, and can be used under the same general conditions as ferritic and martensitic types.
