ASTM A105 Flange

ASME SA105N Blind Flange Manufacturer in India, View Carbon Steel A105 Flanges Dimension and Pressure Rating

The ASTM A105 Flange is a standard most predominantly used carbon steel grade which is used in the production of forge piping components such as flanges. In addition to adhering to the chemical requirements of the specification, at our factory, these specified forged ASTM A105 Carbon Steel Flanges are often subjected to several tests. For instance, tests such as tension, hardness and hydrostatic tests can be performed on the forged CS ASTM A105N Flange as and if required by our clients. Further, this carbon steel Flanges A105 Material which is forged are also required to adhere to not only mechanical parameters like its tensile strength, yield strength and elongation but also to the reduction of area, along with the hardness requirements as well. Typically, the ANSI A105 Flanges are used in industries such as petrochemical, oil and gas, power plant etc.

Exporter & Supplier Of ASME SA 105 Slip On Flange and A105 Carbon Steel Flat Flange As Per ASME/ ANSI B16.5

These grades of Carbon Steel A105 Flanges are used for not only ambient temperature applications, but they are also used for high temperature settings in pressure systems. These A105 carbon steel flanges are subjected to varying heat treatment processes such as normalizing, annealing, tempering, or quenching.
