ASTM A765 Flange

Check dimensions and price list of SA 765 Gr II Blind/ Slip on Flanges, Leading Manufacturer of A765 Gr. I Flange in India

The Astm A765 flange is an adaptor that connects piping equipment to create a piping system. Astm A765 Flange is designed with a chemical composition of chromium, nickel, and molybdenum with vanadium, copper, and a few other constituting alloys. These flanges showcase enhanced resistance to corrosive and reducing media in different conditions. The ASTM A765 Flange is a heat-treated carbon steel and alloy steel forgings that are mandatory for different toughness requirements. These flanges are intended for use in pressure vessels, feed water heaters, and other equipment. They are available in different types of grades to suit different applications.

Ramesh Steel Corporation is one of the leading Carbon Steel SA 765 Gr III Slip On Flange manufacturers in India, producing ASTM A765 Gr. IV Orifice Flanges for Oil and Gas, Petrochemical industry

The A765 Gr. I is designed with a density between 7.8 to 7.9 g/cm3 and is typically used for low carbon steel grades. The grade has a shear modulus between 75 to 80 Gpa with an elastic modulus between 200 to 215Gpa. A765 Gr. II has higher strength compared to the other grade. This grade has a melting point between 14800 to 1526 degrees C and has a maximum service temperature up to 500 degrees C. The A765 Gr. III exhibits a minimum yield strength of 260mpa with a tensile strength between 485 to 655mpa. This grade can be easily elongated by 22% and possess good workability. A765 Gr. IV has a Charpy impact energy of 35J at 20 degrees C while having a Poisson's ratio of 0.29. The grade has an electrical resistivity between 1.43E-7 to 1.74E- 7 Ω·m.
