Steel bar grain direction
網頁1.1 Grain Orientation. In general, grain orientation is obtained as a variable to predict certain properties, such as mechanical properties, where it is referred to as ‘‘slope of grain’’. Most applications are for solid wood (lumber, veneer) where slope of grain is used to predict modulus of elasticity (MOE). 網頁2013年11月9日 · There may not be a critical difference of grain direction when using flat pieces but when we bent steel, especially cold, we absolutely had to know the grain direction. I agree that once finished either by grinding , painting, steel shot blasting, galvanizing etc, you can no longer see the grain direction but its there still until the steel …

Mar 6, 2024. #4. In steels used in construction, it does matter. There are inclusions in the steel that get stretched out in layers in the direction of rolling, almost like layers of damascus. Apply stresses perpendicular to the inclusions and the steel has reduced toughness.
