Chromoly steel is a type of low alloy steel that gets its name from a combination of the words "chromium" and "molybdenum" – two of the major alloying elements. Chromoly steel is often used when more strength is required than that of mild carbon steel, though it often comes at an increase in cost. Chromoly falls under the the …

Tooling Function. Whenever sheet metal is changed on a roll forming line, the roll former's tooling progressively alters the metal's shape. What starts out as coil undergoes any number of changes before a finished product is packaged at the other end. The forming is completed by tool steel rolls as they roll over the work metal.

Roll forming is a continuous manufacturing process, which allows for the economical production of a wide range of profile geometries in large batches.When roll formed profiles are cut to length, process related residual stresses are released. This effect, also known as end flare, results in a deformation of the profile ends at the cut-off.
