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The UNS S31803 (ASTM F51) specification has been largely superseded by UNS S32205 (1.4462, ASTM F60).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).

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.When it comes to uses, SS304 can be found in kitchen sinks and other appliances such as toasters and microwave ovens. SS304 is also used to make pressure vessels, wheel covers as well as for building facades.

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]

Alloy 310 can be used in moderately caburizing, moderately oxidizing, nitriding, cementing and thermal cycling applications when not used at the maximum service temperature.

After tension testing and three-dimensional vibration test, the tearing of the sewn stainless steel pipe occurs almost far away from the welding point or the heated area. This is because the weld less impurities and nitrogen content is slightly higher, so the strength of the weld better than other parts.

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.

Grade 310S Stainless Steel Butt Weld Pipe Fitting contains low Carbon, with higher Nickel and Chromium content curbing Hydrogen sulphide attack, which used in various industries like heat exchangers, furnace parts, shipbuilding, heat treatment baskets, condensers, offshore etc.
The fittings are shaped up and then heated to a high temperature following a rapid cooling closer to the cooling in still air. This rapid cooling adds to the strength of the Stainless Steel 310 Pipe Fittings and makes them much stronger. The SS 310S Fitting is used in industries like the sea water processing, thermal energy generation plants and much domestic piping as well. 310S SS Weld Fittings is used in different pressure classes to cope up with the pressure containment requirement of the application as well.

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.

304/304L stainless steel pipe is a modern version of “18-8” stainless steel, containing approximately 18% chromium and 8% nickel, and is the most commonly specified stainless steel worldwide.

Chromium, nickel, and iron are the primary alloying elements in austenitic stainless steel.

304l stainless steel is easy to work harden. Manufacturing methods involving cold working may require an intermediate annealing stage to mitigate work hardening and avoid tearing or cracking. When fabrication is complete, a full annealing operation should be employed to reduce internal stress and optimize corrosion resistance.
