Both 316 and 316L stainless steel alloys are marine steels, but they do have some key differences. The composition of 316L has a lower proportion of carbon. To meet the requirements of 316L stainless steel, the carbon content cannot exceed 0.03%. This reduces the risk of carbon precipitation, making it a better choice for welding to ensure maximum corrosion resistance.

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.

Chromium oxide is created when chromium and steel react, which gives the corrosion resistant properties to stainless steel. This is one of the reasons stainless steel is great for sanitary valves and other sanitary items, because it does not corrode.

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.

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).

This material is widely used in large gauge welded components and weld annealing is only required when the material is used in high stress environments. Due to the material’s high corrosion resistance, 316L has a wide range of uses, especially in marine applications.

UNS S31603 Elbow also has excellent resistance to pitting corrosion and soaring tensile strength. They are machined to have tough and strong chip characteristics. SS 316L 45 Degree Elbow is also considered to be more resistant to general corrosion and pitting than normal Nichrome.

317/317L is a molybdenum containing austenitic steel with low carbon content. The increased content of chromium, nickel and molybdenum makes the grade more corrosion and chemical resistant. It has reliable robustness at high temperatures and offers an unmatched level of manufacturability. These properties of the SS317/317L facilitate its utilization in the aerospace and steel industries. In addition to this, our SS 317/317L flanges have excellent resistance to intergranular corrosion.

321 Stainless Steel (UNS S32100/ASTM A193 B8T) is a very close relative. While 347 stainless steel is stabilized by the addition of niobium and tantalum to resist intergranular corrosion, 321 is stabilized by the addition of titanium. By adding niobium and tantalum, this material prevents the formation of chromium carbides. Since these elements have a stronger affinity for carbon than chromium, niobium-tantalum carbide precipitates within the grains rather than forming at the grain boundaries.

The Stainless Steel 317L RTJ Flange has two rings as a pair and is connected to the pipes via welding. Just like the socket weld flanges, the SS 317/ 317L Weld Neck Flange has a neck welded onto it for better connection.

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.

It is also not necessary to anneal thin sections after welding. It is widely used in food industry, water, construction, low temperature and high temperature applications. Widely used in premium cutlery, it is described as 18/8, referring to the percentage of chromium and nickel.

Stainless steel UNS S31600 bolts are commonly used in food preparation machinery primarily in chloride atmospheres. SS 316 Hex Bolts are an austenitic nickel-chromium alloy containing molybdenum. SS 316 Heavy Duty Hex Bolts are the ideal steel for use in marine environments as it resists pitting corrosion better than any other steel grade.

The composition of stainless steel 304L flanges contains carbon, nickel, silicon, nitrogen, sulfur, manganese, phosphorus and chromium. 304L is available in different grades depending on the carbon content.

316L is a less carbon variant of 316. Alloy 316L is generally used when welding is required to ensure maximum corrosion resistance. As 316L consists of lower carbon content it results in lesser carbide precipitation which is a result of welding. Our products are renowned for the amazing quality and finishing that they have on offer. Moreover, our products are known to offer maximum utility even under harsh usage, as we put our products through various quality control measures.
