Stainless steel is an alloy of iron that is resistant to rusting. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel’s resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.
A stainless steel pipe system is the product of choice for carrying corrosive or sanitary fluids, slurries and gases, particularly where high pressures, high temperatures or corrosive environments are involved. As a result of the aesthetic properties of stainless steel, pipe is often use in architectural applications.

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.

stainless steel flange is a kind of general steel material, which is widely used to manufacture equipment and parts with high requirements for comprehensive performance (corrosion resistance, formability). stainless steel is a stainless steel grade produced according to American ASTM standards. stainless steel is the most widely used stainless steel and heat-resistant steel. It is applicable to food production equipment, Xitong chemical equipment, nuclear energy, etc.

Stainless steel Grade 254 SMO Flanges is quite tough to machine due to the extremely high work hardening rate and lack of sulfur content; however using sharp tools, overpowered machine tools, positive feeds, good amount of lubrication, and slow speeds tend to provide good machining results.

Type 316L stainless steel in a molybdenum bearing austenitic.

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.

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.

For 304L stainless steel pipe, the range of carbon content in the steel affects the corrosion resistance of the tank. During the welding of steel, a phenomenon called “chromium carbide precipitation” occurs at temperatures between 800 and 1500¡ãF (425 and 815¡ãC). Chromium combines with carbon in the heat affected zone and precipitates as chromium carbide at grain boundaries. As a result, it significantly reduces the corrosion resistance of the steel in this area. Due to the lower carbon content of 304L steel, the risk of chromium carbide precipitation is greatly reduced.
