A plate’s grain direction comes from the mill’s rolling process, which stretches the metallurgical structure and inclusions of the material. The grains run parallel to the rolling direction. Forming with the grain requires less bending force because the material’s ductility is readily stretched. See more When working with plate, pay close attention to whether you are forming with (longitudinal) or across (transverse) the grain direction (see … See more Localized stress can influence forming results, and this limits how tight the inside bend radius can be. Thermal processes like flame and laser cutting harden the edges and produce … See more Hot forming occurs when the plate is between 1,600 and 1,700 degrees F. This reduces or even eliminates strain hardening, cracking of the radius, and distortion of the grain … See more All steels, aluminums, and even plastics exhibit springback upon release from the bending forces.
