AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.

ASTM A312 TP316 is a standard specification for seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipes used in high-temperature and general corrosive service applications. The 316 Seamless Industrial Steel Pipe is made from a combination of chromium, nickel, and molybdenum, which gives SS 316 Seamless Tube excellent resistance to corrosion and rust.

Stainless steel flange is a kind of general steel material, which is widely used in equipment and parts with good comprehensive performance requirements (corrosion resistance and molding).

Stainless steel 304 tubing is available as seamless or welded. Pipes can be drawn as seamless tubes from a single billet or welded from strip or sheet. There are different welding methods such as resistance welding for smaller pipes and electrofusion welding for larger diameter pipes.

Alloy 317L has excellent corrosion resistance in a wide range of chemicals. It resists attack in sulfuric acid, acidic chlorine and phosphoric acid.

316L, however, is a better choice for a project that requires a lot of welding because 316 is more susceptible to weld decay than 316L (corrosion within the weld).

These SS 347 flat washers offer high strength, good corrosion resistance, good mechanical properties up to 600¡ãF (316¡ãC), and good toughness in the base metal and weld.

Another important role of stainless steel flange is that when a section of pipe does not need continuous connection, it needs to be partially blocked. At this time, the pipe can be easily sealed by using the flange.

It is known to possess excellent workability as well.

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.

Stainless steel also contains varying amounts of carbon, silicon and manganese. Other elements, such as nickel and molybdenum, can be added to impart other useful properties such as enhanced formability and enhanced corrosion resistance.

SMO 254 Flanges belong to the ASTM A182 specification with sizes ranging from 1/2 inches to 48 inches. There are different standards to govern the dimensions such as ASME, ANSI, DIN and other international standards.

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.When it comes to uses, SS304 can be found in kitchen sinks and other appliances such as toasters and microwave ovens. SS304 is also used to make pressure vessels, wheel covers as well as for building facades.

Grade 316L, the low carbon version of 316 and is immune from sensitization (grain boundary carbide precipitation).

Grade F22 is a low alloy steel grade with a chromium content between 2% and 2.5%. The content of chromium and molybdenum is twice that of F11 grade. However, due to the maximum content of all alloying elements up to 5%, it is classified as a low alloy steel grade. As a low alloy steel grade, ASTM A182 F22 flanges outperform carbon steel, especially in applications involving high temperatures.

316 stainless steel has a similar chemical composition to 304, but also contains molybdenum. This addition makes it more resistant to corrosion. Like 304, the 316 formulation does not require post weld annealing. 316L stainless steel is almost the same as 316. The only difference is the carbon content. The low carbon content of 316L imparts better corrosion resistance than 316. 316L does not require post weld annealing.

HT PIPE is highly acclaimed manufacturer of the complete range of Stainless steel 304/ 304L pipe fittings such as SS 304 reducer, SS 304 elbow, SS 304 tee, SS 304 cross, SS 304 stub ends and SS 304 pipe bends.

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]

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.

AL-6XN is an upgrade to 300 series alloys such as 316L/1.4435 and 304 when high concentration of chlorides, high temperature, acidic pH levels, and time of contact are introduced to the process.

The addition of molybdenum and chromium to its alloys ensures better mechanical properties and a certain degree of corrosion resistance. ASTM A182 F22 Class 3 flanges have good atmospheric corrosion resistance and some resistance to scaling when they are exposed to high temperatures. The addition of molybdenum to alloys is generally associated with high stiffness and hardness. Therefore, when included in the chemical composition of Astm A182 F22 Class 1 WNRF Flanges, its toughness gives the alloy an advantage over conventional carbon steel grades.

Annealing is a heat treatment process which alters the microstructure of a material to change its mechanical or electrical properties. Typically, in steels, annealing is used to reduce hardness, increase ductility and help eliminate internal stresses.

The austenitic structure of 316 stainless steel provides excellent toughness even at low temperatures.

Bolts hold materials together by applying pressure that tightens the bolt head to the nut. They mate with corresponding threaded holes and nuts to form a bolted connection. Their external thread design makes them easy to tighten with a wrench or pliers. The purpose of a bolt depends on its shape, head type and size. The most common types of bolts include hex head bolts, U-bolts, eye bolts, brackets, lifts, plows and flanges.

304L is preferred. And it lacks a minimum carbon content, which is not ideal for high temperature applications where optimum strength is required, so 304H is the first choice. Thus, 304 is generally limited to rods or sheets that are to be machined into components that do not require welding, or sheets formed in articles, such as kitchen sinks or cookware, which are also not welded.
