About Stainless Steel 446 Flanges

A heat-resistant chromium ferritic alloy called Stainless steel 446 Flanges is used to make goods that can withstand high temperatures. The flanges of this alloy offer excellent resistance to heat corrosions such as sulfidation, oxidation, and others. The heat-resistant alloy 446 flanges can withstand molten copper and brass with ease. Due to the alloy’s high chromium concentration, it is not very pliable. Most boilers and furnace parts are made of this type of flanges.

Properties of Stainless Steel 446 Flanges:

  • To ensure proper pipe connection in the industries, the two ends of the pipes are connected by a flange. Flanges are frequently made from sturdy materials so they can easily withstand connecting pipes.
  • The highest-grade steel flanges are created using sophisticated and cutting-edge technology. The development of the flanges involves applying the recommended procedure. 
  • Because of this composition, the flanges’ minimum tensile and yield strengths are 450 MPa and 205 MPa, respectively.
  • The dimensions and diameters of the SS 446 pipe flange might vary according to different standards and regulations. The flanges’ sizes can range from 12 inches to 48 inches.
  • The use of Stainless Steel 446 Flanges to manage its hardening has resulted in a significant change, necessitating a more considerable heat input to accomplish penetration during arc welding.
  • The SS 446 Flanges might be a suitable and less expensive alternative to high-strength carbon steels due to its corrosion resistance, strength, and ease of construction. Developing a treatment solution for temperatures up to 1900 °F.
  • These flanges are hard and brittle, but they change into a low-emissions martensitic structure when they cool to room temperature. 
  • These flanges are appropriate when temperature change often occurs while manufacturing is underway.
  • The 446 Grade is a common material because of its formability and weldability.

Qualities of the SS 446 flanges:

Stainless Steel 446 Flanges have a lot of great features that make them a more valuable product. The qualities include high tensile strength, low flexibility, durability, machinability, resistance to general corrosion, and resistance to pitting corrosion. 

Testing of 446 SS flanges produced:

The following tests are carried out to evaluate the steel flanges’ quality:
  • An atmospheric pressure test,
  • Micro and macro test
  • Hydrostatic test
  • Raw Material test
  • Hardness test
  • Chemical and mechanical testing test
  • Positive substance identification
