ASTM A350 LF2 Flanges
A350 lf2 flange are intended for low temperature services. These are flanges made up of carbon steel or with low alloy steels. There are A350 Lf2 class 1 and class 2 flange types. Both the types need the notch toughness test to make sure that they are in compliance with the quality that is needed. There are different shapes, sizes, dimensions and grades of the ASTM A350 Lf2 Flanges components and Dinesh Industries is a manufacturer and supplier of all the different types. We are in business for several years and produce all different kinds of flanges in different material grades as well.
