254 SMO flanges

254 SMO flanges

Alloy 254 SMO is an austenitic stainless steel that comes with 5% molybdenum and nitrogen in its chemical composition. The 254 SMO Flanges show high resistance to crevice corrosion and surface corrosion. The ASTM A182 SMO 254 Slip On Flange also shows impact toughness resistance due to chloride stress corrosion cracking and pitting and its strength is twice that of 300 series stainless steel. The SMO 254 Slip On Flange can be considered as a cost-effective substitute for some high nickel and titanium alloys. They come with excellent workability too. The operating temperature of the SMO 254 Plate Flange should range between 982 degrees C and 1149 degrees C.

The size of the ASME B16.5 254 SMO Flange can be found by finding the following measurements:

  • Inner diameter
  • Outer diameter
  • Pitch circle diameter
  • Hole size
  • Thickness

The blind UNS S31254 SMO Flange has no hub or bore in the center. It is like a disc which can be placed at the ends of a piping system to terminate the pipe run. The weld neck ASTM A182 F44 UNS S31254 Flange come with a high hub and they help to relocate the stress to the pipe and thus, reduce high-stress concentration at the bottom of the pipe.

The advantages of SMO 254 Flanges would include:

  • They are designed to be used in seawater and other chloride containing environments.
  • They show good resistance against pitting and crevice corrosion.
  • The material has low carbon thus there is less chances of carbide precipitation at the time of welding.
