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 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.

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]

All steels have the same basic iron and carbon composition, but stainless steel also contains a healthy dose of chromium¡ªthe alloy that gives stainless steel its famous corrosion resistance. There are multiple grades called stainless steel, each with slightly different alloy composition, and therefore slightly different physical characteristics.

While 300 series stainless steels are very popular, they are not universally suitable for all process piping applications. For example, even though they are corrosion resistant, 300 series formulations do not perform well in the presence of chlorides. In these cases, steels with much higher alloy contents such as molybdenum, chromium and nickel are preferred.

Nickel is so important that nickel-containing grades make up 75% of stainless steel production. The best-known of these are Type 304, which has 8% nickel and Type 316, which has 11%.

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.

Although 316L contains less carbon, 316 and 316L stainless steels cost approximately the same.

The 304, 316 and 316L stainless steel formulations are austenitic, a term used to classify the crystal structure of the steel. The structure is achieved by heat treating at very high temperatures followed by quenching ¨C a rapid cooling process that locks the structural features in place. Austenitic formulations are stronger than martensitic or ferritic steels. Ferritic steels are magnetic, have low carbon content, and have poor corrosion resistance.
