Frequently Asked Questions
What are the 431 stainless steel flanges used for?
Stainless Steel 431 Flanges are often used in applications that demand high strength, corrosion resistance, and ease of machining. These flanges are used in various sectors, including chemical processing, oil & gas, petrochemical, aerospace, and marine engineering. Pipes, valves, and equipment in pipelines, pressure tanks, and machines can all be connected using specific applications. Furthermore, Stainless Steel 431 Flanges are used in situations with high temperatures and corrosive chemicals, making them ideal for use in heat exchangers, furnace components, and other high-temperature applications.
What is the hardness of stainless steel 431 Flanges?
When annealed, Stainless Steel 431 Flanges generally have a hardness of 20 to 25 HRC (Rockwell C scale). However, depending on the heat treatment technique and required qualities, the hardness can grow dramatically, reaching values of 50 HRC or more.
Are there any special considerations for handling and storing Stainless Steel 431 Flanges?
Additional concerns for handling and storing Stainless Steel 431 Flanges include safeguarding them against contamination and damage during shipping and storage. Flanges should be cautiously handled to avoid scratches or dents that might jeopardize their structural integrity. Furthermore, maintaining them in a clean, dry environment away from corrosive chemicals and moisture helps to preserve their surface quality and corrosion resistance.
