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

In piping systems, elbows are fittings used to change the direction of the pipeline. They are categorized by angle, with the most common being 45°, 90°, and 180°. Additionally, based on engineering requirements, other non-standard angle elbows such as 60° are also included.
