ASME SA 182 Grade F91 Forged Flanges Manufacturer in India

ASTM A182 F91 material properties
The astm a182 f91 flanges is made up of alloy that consists of different types of elements like carbon, silicon, manganese, chromium, and molybdenum. The presence of around 4% chromium helps in enhancing the corrosion resistance as well as the mechanical properties. The astm a182 f91 flanges comes with a very high strength, with around 275 MPa min yield strength and 485 MPa min tensile strength.
The astm a182 f91 flanges are available in various diameters ranging from ½” to 36”. They are also available in different pressure classes between 150 to 2500. The astm a182 f91 flanges are available in different types of faces for varied requirements. The astm a182 f91 material is available in two classes, wherein class 1 is more widely used. They are used for a wide range of applications across several industries like chemical, petrochemical, oil and gas transportation, etc. The dimensions of these flange can be customized according to requirements.

ASME SA 182 Grade F91 Forged Flanges advantages
The ASME SA 182 Grade F91 Forged Flanges have a very uniform internal structure, and hence there are no chances of imperfections like pores which are present in casting flanges. They are stronger and more reliable. This is due to the tight grain structure of the flange. Also, they are not susceptible to cavities , and there are also no issues like shrinkage. The tight grain structure also helps the ASME SA 182 Grade F91 Forged Flange to resist more wear and tear. They are unlikely to become brittle like the casting flange. Thus, they are used in more harsh environments.
