Carbon Steel Flanges

Refer Specification Chart Of ANSI B16.5 High Yield CS Flange, Low Temperature Carbon Steel Weld Flanges Weight Chart According to ASME B16.5.

The performance of heat treatments on most carbon steels reduces its yield strength and certain mechanical to some degree. However, with High Yield Carbon Steel Plate Flanges, the heat treatment furnishing like tempering or even quenching on these components does not change its yield strength. These components are most likely to have unchanged mechanical properties despite forming operations like bending. While the high content of carbon works well with elevated temperatures, it isn’t easy for steel grades to function at lower temperatures. Which is why low Temperature Carbon Steel Pipe Flanges are specially designed for lower temperature applications. These pipes exhibit outstanding performance down to a temperature of - 50°F. Unlike stainless steels, at low temperature settings, these Carbon Steel Flanges characteristically have moderate strength with superior toughness. ASME B16.5 CS Flanges are produced in the following rating class designations i.e. class 150, 600, 900, 300, 400, 1500, and 2500. Commonly these flanges are manufactured in sizes ranging between NPS 1/2 through NPS 24. The material used for the production of 4 inch Carbon Steel Slip On Flanges is to be either forged or it is to cast.

Carbon Steel Flanges manufacturers in India

Unlike other flanges, a few types of reducing flanges as well as blind flanges which may also include plate materials in addition to forged and cast materials. The ANSI B16.5 is a standard that also includes specifications and recommendations concerning bolting for flanges, Class 150 Carbon Steel Threaded Flange gaskets, along with flange joints.
