What is a carbon steel flange?
and how does it compare to a stainless steel flange?

Like a stainless steel flange,a carbon steel flange is a type of component that used to connect pipes, valves, pumps, and other equipment within piping systems.They offer high strength, durability, and cost-effectiveness.

Carbon steel flange wings rust and oxidize,typically requiring coating before use in humid environments.
Stainless steel contains chromium,which forms its own protective layer,making it the preferred choice in corrosive environments.

In contrast,carbon steel flanges typically exhibit higher tensile strength and hardness.
Stainless steel flanges maintain a bright appearance.Carbon steel flanges appear dull and may develop a reddish-brown discoloration if the coating fails.

Carbon steel flanges have lower upfront costs,while stainless steel flanges are significantly more expensive.
