ASTM A182 F91 Flanges and ASME SA182 F91 Type 2 Weld Neck/ Blind Flange

Alloy Steel F91 Type 2 Weld Neck And Blind Flanges manufacturer In Mumbai According ASME/ ANSI B16.5 Class 150 To 300#

ASTM is an American standard that is divided into different grades that specify the material, dimension, and other properties of a particular product. One such product is ASTM A182 F91 Flanges. This specification covers both rolled as well as forged alloy along with stainless steel fittings. SA182 F91 RTJ Flange is usually used in a high temperature environment. Alloy Steel F91 Type 2 Weld Neck Flanges are available in various types such as austenitic, martensitic, ferritic, and stainless steel. AS F91 Blind Flanges manufacturer In India add molybdenum and nickel to these alloys in trace amounts to enhance the ductility of these flanges even at sub zero temperature.

ASME SA182 F91 Slip On Flanges also have good mechanical properties when compared to other grades because of the addition of these elements. It is usually air hardened that reduces the possibility of the thick section of these flanges cracking during heat treatment. A182 F91 Type 1 Socket Weld Flange also offers resistance to corrosion, along with good weldability. The alloy used in manufacturing the Grade F91 Forged Pipe Flanges also offer good resistance to high temperature and high pressure. These flanges are ductile, tough, and strong due to the alloy used in them and are therefore durable.

ASTM A182 F91 Plate Flanges also offer resistance to scaling in an aqueous medium as well as oxidation. They are used in the nuclear power industry, bitumen, heavy oil refineries, and petrochemicals, and acids. Alloy Steel A182 F91 Raised Face Flanges manufactured by us contain the highest quality raw material and are made using modern technology. This, therefore, helps us in obtaining economies of scale in manufacturing Chrome Moly A182 F91 Threaded Flange and supplying them at comparatively lower rates when compared to our competitors.
