ASTM A350 Lf2 Flanges 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 A350 lf2 flange components and Naveen 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.

The ASTM A350 lf2 forged flange types are stronger because they are forged from one piece of metal and could be used in applications where strength is required. These flanges could also be welded with the piping system with ease. For applications that require toughness and hardenability, the ASME sa 3150 lf2 flanges can be used. There are conditions at which killed carbon products are preferred.  For such applications, we supply the A350 Lf2 killed carbon steel flanges to meet the needs. There are different dimensions and scales involved as well. Please don’t hesitate to contact us to know more about or to inquire anything about our products.
