ASME/ ANSI B16.5 Class 150 Flat Face Flange in Stainless Steel and Carbon Steel

Biggest DIN 2576 Carbon Steel Flat Face Flange Manufacturers In India and Largest ANSI B16.5 Stainless Steel Flat Face Flange Suppliers in Mumbai.


Commonly materials like stainless steel, alloy steel and carbon steel are preferred for the production of flanges. This is because out of all the metal alloys available, these metals are inexpensive, their properties range from mid to high levels, they are versatile and make the high-quality ASME B16.5 Flat Face Flange. Furthermore, alloy steels and stainless steels have better corrosion resistance properties. These properties are far better than the Carbon Steel Flat Face Flange. But unlike stainless and alloy steels, carbon steels are tough and they perform well despite being exposed to low-temperature environments. Another aspect of carbon steel is that there is no change in the ANSI B16.5 Flange Flat Dimensions when used in cold temperature conditions. Usually, stainless steel alloys are not resilient to being used at cryogenic temperatures.

Since they are ductile they get easily deformed. This being said, not all Stainless Steel Flat Face Slip On Flange is damaged when used at extremely low temperatures. Grades like 304 Stainless Steel Flat Flange function well, without any significant loss in either tensile strength or in its mechanical properties. Having standardised components makes assembling piping systems easy. The most common Flat Face Flange Standards are from the ASTM or from Ansi, both of which act as guidelines for the manufacturer.
