WebJul 17, 2016 · Bending steel is defined as deforming steel around a straight axis. We use force to manipulate steel until it reaches a desired angle or shape. ... Bending Direction The bend must always be performed perpendicular – or at most 45-degrees – to the grain lamination direction. This will increase bent resistance and reduce the risk of fractures WebBending causes the grains to spread even more which in turn, causes cracking on the outside radius of the bend. Therefore, it is imperative when forming any steel, but in particular for very hard wear resistant steels, to know the grain direction and always bend it perpendicular to the grain. Most Wear Steels Require Pre-Heating Before Bending
