Stainless steel elbows differ from carbon steel elbows primarily in material; their chemical composition ensures the surface remains rust-free and corrosion-resistant for extended periods.

In piping systems, elbows are pipe fittings used to change the direction of the pipeline. Commonly, there are three types by angle: 45°, 90°, and 180°. Additionally, other non-standard angle elbows, such as 60°, are included according to engineering requirements.
