All You Need to Know About Stainless Steel 310 Pipes

 

Stainless Steel 310 Pipes are austenitic and have a medium carbon content. They are highly appropriate for applications in high temperatures. The SS UNS S31000 is highly resistant to oxidation and corrosion. The anti-corrosive properties are due to the chromium-nickel composition. It is a high chromium and medium nickel composing alloy. They are highly suitable for applications in environments containing Hydrogen Sulphide. The Stainless Steel 310 Pipes is commonly used in severe cryogenic environment applications. Grade 310 SS Rods are incredibly tough and have low magnetism. These Rods do not work well in severe carburizing environments like petrochemical industries. The Stainless Steel 310 Pipes are hardened by the cold working procedure. But this process is not usually practiced. These pipes cannot be hardened by hot working them. Stainless Steel 310 Pipes are available in a variety of forms including SS 310 Welded pipes, seamless pipes, etc.


Industrial Applications:

Applications of the Stainless Steel 310 Pipes include kilns, steam boilers, coal gasifier components, lead pots, burners, retorts, mufflers, combustion chambers, annealing covers, food processing equipment, and cryogenic structures.

Machinability:

Stainless Steel 310 Pipes have mediocre machinability. It is tough to work harden this material. The work-hardened layer can be removed by slow speed, sharp tools, good lubrication, and heavy cuts. Stainless Steel 310 Pipes require powerful machines and rigid tools to carry out the machining process.

Heat Treatment and Resistance

Stainless Steel 310 Pipes are heated up to 1040-1065 degree C temperature range for annealing procedure. They hold up at a high temperature until soaked thoroughly and are the water quenched. Stainless Steel 310 Pipes resist oxidation and other corrosions caused by air up to 1035 C. The UNS S31000 Stainless Steel pipes are resistant to oxidation, sulfidation, and carburization.

Weldability: - Do’s and don’ts

Welding of Stainless Steel 310 Pipes is done using filler metals and electrodes. Argon is used as a shielding gas. Pre and post-heating is not a necessity. For prolonged utility and corrosion resistance in liquids, post-weld annealing is important. To remove high-temperature oxides, Stainless Steel 310 Pipes go through pickling and passivation of the surface. This is an essential process to restore aqueous corrosion resistance post the welding process. The welding slag removal is highly essential.

Fabrication:

Stainless Steel 310 Pipes are easily cold formed using standard equipment and methods. Post forging process annealing is highly recommended to get rid of stress caused during the forging process. The SS UNS S31000 Bars are fabricated in temperatures ranging from 975–1175-degree C.

How is Aluminum Plate made-

Image
  The Aluminum Plate manufacturing process can be divided into three phases; the first bauxite, which contains aluminum, is extracted from the ground. Bauxites are transformed into alumina or aluminum oxide and finally, in the third step, pure aluminum is produced using electrolytic reduction, a process in which aluminum oxide is broken down into its components using electric current. Almost   about 45 tons of bauxite is made into two tons of alumina from which about one tons of aluminum can be manufactured. Many minerals are available in the world, whose aluminum can be done, but the most common raw materials are bauxite. Bauxite is a mineral composed mainly of aluminum oxide mixed with other minerals. Bauxite is considered high quality if it contains more than 50% aluminum oxide. v    v    Bauxite supplies- ·          Confirmed global bauxite supplies are estimated at 18.6 billion tons. At the current level of...

Difference between Incoloy 825 Hex Bolts and 925 Hex Bolts-

Image
  Alloy 825  (Incoloy 825, UNS N08825, 2.4858) and  Alloy 925  (Incoloy 925, UNS N09925) are nearly identical in composition, and therefore provide very similar corrosion resistance and physical properties. However, Alloy 925 provides significantly higher levels of strength as it benefits from precipitation strengthening. Small additions are made to its composition, which allows the formation of microscopic precipitates when the alloy is subjected to an extended heat-treatment process. These fine precipitates increase the yield strength by up to 4x. v   Features of Incoloy 825 Hex Bolts and 925 Hex Bolts- ·          Incoloy 825 Hex Bolts  are highly resistant to corrosion. It has a high nickel content which is sufficient to eliminate stress corrosion of chloride ions and is a very stable austenite structure. The copper and molybdenum contents allow the alloy to remove reducing agents and acids. Its chromium provid...

The Most Common Flange Types

Image
  The use of different types of flanges for different purposes is vital. Standard types of flanges : these flanges are used for piping applications, which mainly depend on the required strength for the flanged joint. These types of flanges are basically used for welding connections, and to facilitate maintenance operations. a)     Blind flanges :   Unlike all the types of flanges mentioned above, this flange type does not have a center hole. Stainless Steel Blind Flanges are mostly used to seal the end or opening of a pipe. These are used to blind or seal a pipeline, a valve /pressure vessel and block the flow of the fluid. Blind flanges allow easy access to the pipelines, because they can be easily unbolted to let the operator execute activities inside the terminal end of the pipe. b)    Slip on flanges : This type of a flange is connected to the pipe or fittings by two fillet welds, from which one is executed outside and one is executed inside...
