Stainless steel 310 flanges

Stainless Steel 310 Flanges

Stainless Steel 310 material offers high temperature stability and is used for applications that require moderate strength. The 310 Stainless Steel Flanges are mainly found in high temperature applications. The Stainless Steel 310 Flanges offer oxidation resistance at elevated temperature conditions going up to 2000 degrees F, under the mild cyclic conditions. The 310 SS Weld Neck Flange material can be a great alternative to alloy 330 or Inconel. Even though the UNS S31000 SORF Flange offers high temperature resistance and slightly less strength, it comes at a lower price. The AISI 310 Threaded Flange can be used in moderately oxidizing, carburizing, nitriding, cementing, and thermal cycling applications, at the maximum servicing temperature. The A182 F310 Forged Flange is known for showing good resistance to sulfidation and various other forms of hot corrosion. Even though the Inox 310 WNRF Flange is popular for its properties at elevated temperatures, it also shows good performance in cryogenic temperature conditions.

The benefits of ASTM A182 310 Plate Flange are:

  • It helps to save space
  • It is light weighted
  • It ensures no leakage occurs at the joint, which means it gives good sealing performance.

However, the 310 stainless steel plate flanges have poor rigidity, and thus, they should not be used in chemical process piping systems.

Even though the SA182 F310 Blind Flange is ideal to be used in high temperature conditions, they should not be exposed to repeated thermal shock. The shocks can be due to repeated liquid quenching or in environments where various aqueous corrosion contaminants are present.
The SA 182 310 Reducing Flange comes with several benefits like it can resist thermal fatigue. The DIN 1.4841 Socket Weld Flange also has low magnetic permeability, with good ductility and weldability. Due to all these properties, the DIN 1.4841 Socket Weld Flange can be used in petrochemical industries. The SUS 310 Screwed Flange has high temperature properties, which make it ideal for ore processing. The F310 stainless steel RTJ Flange is also used for various applications in steel plants and power generation.

The SA 182 F310 Lapped joint Flange can be easily fabricated due to their low carbon content. ASTM A182 Grade F310 material is used in the fertilizer industry due to their mild cyclic operations. The A182 Gr F310 Lap Joint Flange is also used in extremely high temperature services like thermal processing and power generation, as they retain their toughness in elevated temperature conditions.

Depending on particular usage, the SA 182 Gr F310 Slip On Flange of size ½” NB to 12” NB can be used for the petrochemical industry.
