Good weldability, relatively soft and strengthen with cold work during forming or drawing. The K Factor, a fictional TV show from British television show Harry Hill's TV Burp spoofing the X Factor. The k-factor is defined as the neutral-axis shift during bending (t) divided by the material thickness (Mt) Of all the mathematical constants in precision sheet metal fabrication, the k-factor stands out. Widely used in cold forming operations such as heading, upsetting, and extrusion. For most of our sheet metal this resulted in flat pattern differences of less than. Well, when a sheet is bent in the press brake, the part of the sheet close to and in contact with the punch elongate to compensate for the given bend. Cut a blank to a specific length (say 100mm) and measure it as accurately as possible. Hot rolled steel can be bent parallel to the rolling direction. Most sheet metal materials will conform to the calculations. Mathematically k factor value is equal to the ratio of position of neutral axis and sheet thickness. The K Factor, a fictional TV show from British television show Harry Hill's TV Burp spoofing the X Factor.
