Angles in stainless steel are often used in buildings and other constructions for which welding is a necessity. For this reason, angle profiles are available in austenitic grades which combine good corrosion resistance with ease of welding. The profiles that are stocked have equal leg lengths. Angle bars are manufactured by hot rolling on a bar mill in the same way as rounds. After rolling, they are then annealed and pickled which results in a scale-free surface denoted 1D.
