For 304L, the recommended packing is 308L. Heavy welded sections may require post weld annealing. The 304L does not require this step. If post weld heat treatment is not possible, grade 321 can be used.

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.

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The UNS S31803 (ASTM F51) specification has been largely superseded by UNS S32205 (1.4462, ASTM F60).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

Stainless 316 grades cost more due to their better corrosion resistance. This higher grade alloy is especially recommended for applications where the alloy is exposed to chlorinated solutions and chlorides, including seawater.

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.

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.

Type 316L stainless steel requires weld annealing only in high stress applications.

316L Pipe Fittings the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel.

Basically, using 304L eliminates the need to anneal welded joints before using the full metal form, saving time and effort. In fact, both 304 and 304L can be used for many of the same applications. The differences are usually so small that one is not considered more useful than the other. When greater corrosion resistance is required, other alloys, such as grade 316 stainless steel, are often considered as an alternative.

The SS 304 Elbow is one of the key components in the pressure piping system. It basically helps to change the direction of flow in the pipe run. These ASTM A403 Gr WP304 Buttweld Fittings help to connect two pipes with the same or different nominal diameters so as to change the fluid direction by 45 or 90 degrees.

One exception, however, are strongly oxidizing acids such as nitric acid. Alloys that contain molybdenum generally do not perform as well in these environments.?

Applications and Materials
Normalizing is mainly used for normalizing the structure of carbon steel and low alloy steel after forging, hot rolling or casting. The hardness obtained after normalizing depends on the steel dimensional analysis and the cooling rate used (approximately 100-250 HB).
