The stainless steel flange is austenitic chromium nickel stainless steel, which has good oxidation resistance and corrosion resistance. Due to the high content of chromium and nickel, it has better creep strength, can work continuously at high temperatures, and has excellent high temperature resistance.

Austenitic stainless steels are susceptible to stress corrosion cracking (SCC) in halide environments. Although type 316 alloys are more resistant to SCC than 18Cr-8 Ni alloys due to their molybdenum content, they are still susceptible. Conditions that produce SCC are: (1) the presence of halide ions (usually chloride ions), (2) residual tensile stress, and (3) temperatures in excess of about 120¡ãF (49¡ãC).

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

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.

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.

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).

All our ranges of 310 310S Stainless Steel Flanges that we provide are designed by effectively using pure quality of raw material, using refined technology and not to forget as per the national and international product quality standards.

The two most common stainless steel grades are 304 and 316. The main difference is the addition of molybdenum, an alloy that significantly improves corrosion resistance, especially in environments with more salt or chloride exposure.

Grade 1.4404 or 316L is an austenitic stainless steel AISI 316 with very good corrosion resistance due to its high chromium and molybdenum content and low carbon content. Its strength in the hardened state is about 600 MPa for large diameters, but for small sections, the strength can be increased by cold working.

Annealing between 1050 and 1080¡ãC can be done after forging, followed by rapid quenching, especially to restore corrosion resistance, but there is no heat treatment to harden 316L.
