180° Long Radius and 180° Short Radius Elbows are manufactured using robust materials like stainless steel, carbon steel, and alloys such as Duplex and Super Duplex steel. Their composition includes essential elements like chromium (16-25%), nickel (8-14%), and molybdenum (2-4%), offering excellent corrosion resistance and durability. Mechanical properties include high tensile strength (500-900 MPa), yield strength (250-700 MPa), and good elongation (20-30%), ensuring they withstand high pressures and temperatures. The Long Radius Elbow provides gradual directional changes with reduced turbulence, while the Short Radius Elbow suits tight spaces, maintaining flow efficiency.

On the other hand, **180° Short Radius Elbows** feature a curvature radius equal to the pipe diameter, allowing for sharper directional changes. They are particularly suited for tight piping configurations where space is at a premium, although they do create a slightly higher pressure drop and turbulence compared to their long radius counterparts. Short radius elbows are also available in various materials, offering durability, high tensile strength, and resistance to wear, corrosion, and extreme temperatures.
