AISI 4130 Flange

Oldest SAE 4130 Weld Neck Flange Manufacturer in India, Check Dimension and Price list of Chromoly 4130 Blind Flanges

The AISI 4130 grade is a low alloy steel grade that has many strengthening agents. An AISI 4130 Flange is designed with a superior chemical composition of chromium and molybdenum with other constituting alloys. This gives the versatile Chrome Moly Flanges outstanding resistance against corrosion and oxidation in different setups. These flanges can work in low as well as high-temperature conditions due to their enhanced strength and toughness. The Chromoly Flanges are low carbon grades that have good flexibility and hardenability. Designed with a density of 7.85 g/cm3, these flanges exhibit a melting point of 1432 degrees C. An SAE 4130 Flange provides support and strength to a piping fixture as it is put through vigorous stress due to the flow of fluids and gases. These flanges have a minimum tensile strength of 81200 psi with a minimum yield strength of 66700 psi. The AISI 4130 75k Flange is designed with a hardness of 217 max Brinell. These flanges can be elongated at the break by 21.50% and have a bulk modulus of 140Gpa with a shear modulus of 80Gpa. In the AISI 4130 60k Flange the reduction area is 59.6%, and it exhibits a thermal conductivity of 42.7 W/mK at 100 degrees C. These flanges can be custom designed in different sizes and shapes to meet all customer requirements.

The 4130 WNRJ Flanges are high-strength flanges designed with a long protruding hub. These flanges are butt-welded in place and can be used for vigorous movement of fluids and gases in the system. Contrary to this, an AISI 4130 Blind Flange is designed without any face or boring center. These flanges are used to seal the end of high pressure and temperature media. They are generally bolted and allow room for inspection or maintenance.
