Stainless steel is an alloy of iron that is resistant to rusting and corrosion. 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
Completely and infinitely recyclable, stainless steel is the ¡°green material¡± par excellence. In fact, within the construction sector, its actual recovery rate is close to 100%.
Stainless steel is also environmentally neutral and inert, and its longevity ensures it meets the needs of sustainable construction. Furthermore, it does not leach compounds that could modify its composition when in contact with elements like water.
Stainless steel must contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.
In addition to these environmental benefits, stainless steel is also aesthetically appealing, extremely hygienic, easy to maintain, highly durable and offers a wide variety of aspects. As a result, stainless steel can be found in many everyday objects. It also plays a prominent role in an array of industries, including energy, transportation, building, research, medicine, food and logistics.

304 stainless steel has excellent resistance to a wide range of atmospheric environments and many corrosive media. It will experience pitting and crevice corrosion in warm chloride environments, and stress corrosion cracking above about 60 ¡ãC. It is considered to be resistant to pitting corrosion in water up to about 400 mg/L chloride at ambient temperature, decreasing to about 150 mg/L at 60 ¡ãC.

The stainless steel water supply pipe flange has all the properties of stainless steel materials, one of which is the strong corrosion resistance, which can permanently maintain the integrity of the design.

ASTM A269 Alloy 254 Seamless Pipe Material is a very high end austenitic stainless steel.

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.

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.

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.

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.
