The low alloy steel pipe flanges also tend to provide better mechanical properties as opposed to many conventional, standard mild or carbon steels.
Alloy Steel Flanges is a forged or cast ring of steel designed to connect mechanically sections of pipe or join pipe to a pressure vessel, valve, pump any other piece of equipment.
These alloys typically comprise of about 1 % to 5% of the steel’s content and are usually added based on their ability to provide a very specific attribute for their end use.
For instance, the addition of molybdenum in the alloy steel plate flanges, offers an improved material strength.
Adding nickel adds toughness to the alloy. Similarly adding chromium to chrome moly flanges aids in enhancing other mechanical properties such as temperature strength, hardness, as well as corrosion resistance.
Besides these elements the addition of trace amounts of both Manganese and silicon, other set of common alloying elements, provides the alloy steel threaded flanges with excellent deoxidizing capabilities.
Despite adding these elements, low alloy steel flanges aren’t necessarily difficult to weld. The key to achieve a successful performance of the welding operation is by knowing exactly what type of low-alloy steel you have.
Which means that one has to know if the alloy steel flange material is critical to achieving good weld integrity and the need for proper filler metal selection.High heat resistance steel grades are generally known as Chromium Molybdenum Steel.
A low alloy steel flanges series mostly consists of approximately 0.5% to 9% of Chromium. And the content of Molybdenum in the alloy steel flanges ranges anywhere between 0.5% to 1% .
Alloy Steel Flange Material can differ according to its chemical composition. Low Alloy Steel Flanges are widely used for automotive and aerospace bodies, offshore and onshore structural engineering plates and railway lines.
The Chromium content in the alloy aids in improving its anti-oxidization and anti-corrosion properties. This steel is usually supplied by the alloy steel flanges manufacturers in India in an annealed or normalized and tempered condition.
Chromium-Molybdenum alloy steel flanges dimensions has been widely used in the many areas. Their utilization can be seen in areas such as steam power equipment, petrol chemical industry, and high temperature services.
It has chemical composition, such as nickel, nickel-chromium, molybdenum, chromium-molybdenum steels etc.
Chrome moly flanges provide improved levels of chromium and molybdenum. The addition of chromium helps to increase itshardenability and corrosion resistance,
Alloy Steel Threaded Flanges are widely demanded as pipe flanges i.e called as threaded flanges which is useful in different industrial applications. It is also known as screwed flange and it has a thread inside the flange bore which fits on the pipe with matching male thread on the pipe.
Among alloy steel grades, when metals like Nickel, Chromium and Molybdenum along with other alloying element content consist of less than 10.5% of the total alloy percentage, they are defined as low alloy steels.Generally, most low alloy steel flanges possess a precise chemical composition.
ASTM A182 Alloy Steel Blind Flanges is a solid disk used to block off a pipeline or to create a stop. It has mounting holes around the perimeter and the gasket sealing rings are machined into the mating surface.
Alloy steel flanges have corrosion oxidation stress corrosion cracking and crevice corrosion resistance.
A182 alloy flange has good dimensional accuracy.
When moving high-temperature or corrosive media through Chrome Alloy Pipe from one process to the next, flanges capable of withstanding harsh environments are critical

Chrome moly alloy flanges connect pipes, valves, pumps and other equipment, forming a piping system.
They are ideal for applications carrying corrosive or high-temperature fluids or gases. Industries that could benefit from chrome moly flanges include: Oil and Gas, Refinery, Power Generation, and Chemical Processing.
This specification covers forged low alloy flanges for use in pressure systems manufactured to specified dimensions or industry standard dimensional specifications.
These are available in different types such as Slip On Flanges., Blind Flanges, Weld Neck Flanges, Socket Weld Flanges, Orifice Flanges, Spectacle Blind Flanges, Screwed / Threaded Flanges, Reducing Flanges, and Ring Type Joint Flanges (RTJ).
Other than carbon, these contain in them substantial quantities of nickel, manganese, chromium, silicon, tungsten, vanadium, molybdenum.
These are also added with limited amounts of elements like sulphur, silicon, manganese and phosphorous that helps in increasing ¨C Hardness, Strength, Chemical resistance, and more.
Alloy A182 flange also has durability and longevity.
While the term alloy steel could even apply to stainless steel grades, the ASTM specification or ANSI standard used to produce the Alloy Steel Flanges would give the buyer details regarding the chemistry details of these products.
