Grain direction bending
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 WebJan 3, 2014 · Step 5. Write that down! Mark or take note of the direction grain. One way to do this is to draw faint lines in the direction of the grain on the backside of the material. …

This manufacturing method is where hot metal is compressed through … WebStrength properties of wood increase with its decreasing moisture content. For example, air-dried wood with average moisture content of 12-13 percent will have higher strength properties than that of wood with 20 percent …
WebAug 19, 2024 · The main parameter that influences the bending strength of timber from tropical hardwood is the slope of grain. Although, in the grading rules, a specific threshold value is given, in these hardwoods, the global slope of grain is very difficult to quantify by visual assessment. The slope of grain measured after testing gives a better indication, … WebNov 7, 2024 · Bending “across” or “traverse” to the grain is when the bend line runs perpendicular to the grain, which makes for a stronger bend that’s less likely to crack (see Figure 2). Bending parallel to the grain will …
