20Mn5 Steel Flange

20Mn5 Steel Flange

We are leading 20Mn5N Forging Flange Manufacturer in India, Check latest price list of Carbon Steel C22 Flanges

The 20Mn5 steel is a structural steel grade that is seen in high-temperature applications. The 20Mn5 Steel Flange is designed with a chemical composition of carbon, silicon, manganese, nickel, phosphorous, sulfur, chromium, molybdenum, and aluminum. The content embedded in these flanges gives them enhanced strength and good corrosion resistance properties in different setups. 20Mn5N Flanges are supplied in normalized conditions. These flanges have a minimum tensile strength of 530mpa with a minimum yield strength of 300mpa. These modules have an impact energy of 55J at 20 degrees C in the system. The 20Mn5V Flanges are heat-treated at temperatures of 1569 degrees C to 1691 degrees C. These flanges have superior strength and provide support to different applications. The robust EN 10250-2 Flanges are quality assured and designed with the best raw materials and latest technology by our renowned technicians.

Biggest supplier of 20Mn5V Flanges and Carbon Steel 20Mn5 Forged Flange in Size range of 1/2 to 24 inch

The Carbon Steel 20Mn5V Threaded Flange is designed with threads that align directly to the threads on the pipe surface. These flanges don’t require to be welded in place and are generally seen in low pressure and temperature applications. The robust EN 1.1133 Lap Joint Flange is manufactured with a two-component assembly consisting of a stub end and a ring-type sealing. This allows it to swivel around the pipe easily allowing it to easily maneuver in the system. As these flanges don’t come in contact with fluids or gases constantly they offer a long service life. The 20Mn5 Carbon steel Forging is a material that helps in maximizing the natural strength and machinability of a forged material grade. The cost of these forgings is lower than other types of forgings. The versatile Carbon Steel C22 Flanges are seen in use in equipment that is used in high temperatures and requires enhanced strength to work in these harsh conditions.
