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.

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]

It is much more resistant to sulfuric acid, chloride, bromide, iodide and fatty acid solutions at high temperatures. The manufacture of certain pharmaceuticals requires the use of molybdenum-containing stainless steel to avoid excessive metal contamination.

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 Characteristics
Type 316 stainless steel tubing is similar to 304, but with the addition of molybdenum, which improves the alloys corrosion resistance. The austenitic structure allows excellent toughness, even down to extremely low temperatures. These grades have excellent weldability, with or without the addition of filler metal. 316 / 316L stainless tube is available as round, square or rectangular shapes. It is available as welded and seamless. It contains additional molybdenum and nickel than 304 stainless, which increases corrosion resistance of the metal. Decreased weldability is exhibited in 316L alloys due to increased carbon in the alloy. It is used for tube in more aggressive environments than 304 tube.

Stainless steel washers are versatile, have excellent corrosion resistance, and have reactive properties when exposed to high temperatures.

Steel pipes can be disintegrated on the basis of its application. Typical applications of steel pipes are in the area of water pipelines, industrial water lines, oil pipe lines, cross country pipe line, agriculture and irrigation pipes, tube lines for natural gas, chemical industries, automobile industry, construction industries and other purposes.

The alloy has excellent resistance to intergranular corrosion in the as-welded condition.

ASTM A312 TP 310 is a medium carbon austenitic stainless steel suitable for high pressure and high temperature service. There are different grades such as ASME A213 and 312. Grade 310 is an austenitic stainless steel with excellent high temperature properties, as well as good ductility and weldability. Type 310 stainless steel tubing is typically used in high temperature applications. The high chromium and nickel content of grade 310 steel pipe provides excellent corrosion and oxidation resistance, as well as excellent strength at temperatures up to 2100¡ãF.

Stainless steel is an iron alloy containing at least 10.5% chromium. Chromium produces a thin layer of oxide on the surface of the steel, called a “passivation layer”.

The Stainless Steel 304 Pipe Fittings are also strong. They have 205MPa minimum yield strength and 515MPa minimum tensile strength.

The UNS S31254 Weld Neck Flange is preferred in welding applications. These flanges can hold the pipe in place during welding. The material has up to 1390 degrees Celsius melting point so that it could be used in high temperature and high pressure applications such as power generation, heat exchangers, boiler and petrochemical industrial applications.

One of the advantages of stainless steel over 316 stainless steel is that it is biocleaner than aluminum and copper, with biocleanability comparable to glass. The cleanability, strength and corrosion resistance of stainless steel have prompted the use of stainless steel in pharmaceutical and food processing plants.

En la nueva estructura, se ha encontrado que 254SMO en muchos casos es una alternativa tecnicamente adecuada y de menor costo a las aleaciones a base de niquel y titanio.

If your outdoor appliance enclosure is rusted, not only is there a danger of exposing all critical electrical components inside, but it can be expensive to replace in the event of a short. We’re talking about parts damage and replacement, repair costs, including labor and downtime. I’ve seen some real horror shows when the shell is rusted. We have found that using 316 stainless steel instead of 304 stainless steel on outdoor enclosures that will be exposed to various elements, such as oil rigs, not only increases the life of the enclosure, it is also safer.

316L stainless steel is an austenitic alloy often referred to as “marine grade stainless steel” because it is used in nearly 90% of marine applications – including filtration. In addition to metals such as iron and nickel, 316L contains 16-18% chromium and 2-3% molybdenum. These elements are important because they improve the alloy’s corrosion resistance; chromium interacts with oxygen in seawater to form a protective layer of chromium oxide, while molybdenum improves the metal’s resistance to pitting corrosion. Additionally, 316L has a lower carbon content (hence the use of “L” in its name), which gives it better protection against corrosion.
