How grain size and direction affects sheet metal parts
How grain size and direction affects sheet metal parts The grain size and direction of sheet metal parts have a significant effect on the mechanical properties, surface finish, and formability of the parts. This article will explore how grain size and direction affect sheet metal parts and what can be done to minimize the effects. Grain Size and Direction Grain size is defined as the size of the crystals that make up the metal. It is measured in microns (µm). The grain size affects the hardness, ductility, and tensile strength of a material. Generally, the smaller the grain size, the…
