These are tough ?anges meant for highly corrosive environments like urea production
plants. They come in di?erent types. These are weld neck, blind, ori?ce, long weld neck,
forged, reducing, and threaded ?anges. They have high chromium content that protects
even the threads when subjected to high temperatures. The ?anges 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 ?anges 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 ?anges are composed of various elements like sulfur, nickel, nitrogen,
manganese, and chromium. The ?anges 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 ?anges are used in the following areas:
• Salty water equipment.
• Nitrogen processing.
• Crude oil processing.
• Pharmaceutical manufacturing.
• High heart industries.
