Alloy Steel Flanges

Customized high quality ASTM A182 Low Alloy Steel flanges, Check Alloy Steel Flange Material

Alloy Steel Flanges are made in different steel alloys. The flanges vary in dimensions and types. There are ½ inches through 48 inches of nominal diameter sizes of flanges. Navstar Steel is a leading manufacturer of the ASTM A182 Low Alloy Steel flanges as well as the other types of alloys. The ASTM A 182 specification specifies flanges for high pressure services.

Alloy Steel Blind Flanges, ASME SA 182 AS Pipe Flange, ANSI B16.5 Alloy Steel Slip On Flange Price in India

The flanges also come in B16.5, B16.47 and other standards and dimensions. The Alloy Steel Flange Material can vary according to the chemical composition. The grade 304 flanges are the most commonly used flanges and they have 18% chromium and 8% nickel in the composition. The ANSI B16.5 Alloy Steel Slip On Flange is a flange type that allows the pipes to slip onto the flange and makes the connection in a precise locations.


Seamless pipes are used with slip on flanges to make the process smooth. The Alloy Steel Blind Flanges are used to close a pipe connection. There are different types and grades of the blind flanges as well. There are other different types of ASME SA 182 AS Pipe Flanges such as the weld neck flanges and socket weld flanges each specified for a particular role. The flanges can be threaded, ring type joint, lap joint, weld neck or socket welded. The Alloy Steel Weld Neck Flange has a welded neck onto it that holds larger pipes in place for easy welding and installation. As one of the leading Alloy Steel Flanges Manufacturers in India we supply all different types of flanges in all material grades. Please contact us for your alloy steel flange needs.
