These are tough flanges meant for highly corrosive environments like urea production plants. They come in different types. These are weld neck, blind, orifice, long weld neck,forged, reducing, and threaded flanges. They have high chromium content that protects even the threads when subjected to high temperatures. The flanges are also resistant to

oxidation and carburization. They are categorized into 6 classes which are #150, #300,#600, #900, #1500 and #2500.


Properties of Stainless steel 310H Flanges

Mechanical- They can stand a maximum temperature of 14000 C. The tensile strength of the flanges is 515MPa, and the yield strength is 205MPa. They have a high density to support excess pressure. They have a 40% elongation capacity.

Chemical- The flanges are composed of various elements like sulfur, nickel, nitrogen, manganese, and chromium. The flanges are commonly referred to as 18/8 which represents chromium and nickel percentages. The elements form a formidable bond that cannot collapse to pressure.




The 310H flanges are used in the following areas:

• Salty water equipment.

• Nitrogen processing.

• Crude oil processing.

• Pharmaceutical manufacturing.

• High heart industries.
