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 an extended period.

In piping systems, elbows are fittings used to change the direction of the pipeline. Commonly available in 45°, 90°, and 180° angles, additional non-standard angles such as 60° elbows are also available based on engineering requirements.
