Impact resistance in wear resistant steel is usually defined as the amount of energy that a material can withstand when it is suddenly hit with a load or force. Think in terms of a steel plate or steel parts being hit by a very hard object like rocks hitting a grizzly screen. It is measured as the amount of force required to crack or deform the steel, and is measured in foot-pounds per inch or joules per centimeter. (more…)
Tool steels like Toolox 33 Steel and Toolox 44 Steel are designed to be made into tools, hence the name. Specifically, they are designed to be very hard, to resist deformation, resist wearing and, in some cases, to hold an edge. Toolox Steel is used to make tools for cutting, pressing, extruding, injection molding and to form other materials into tools. (more…)
There are three factors which determine how a wear resistant steel should be utilized. Hardness is a steel’s ability to withstand friction or wearing away by material sliding over its surface. Toughness is a steel’s ability to withstand impact or hitting. However, ideal hardness also requires ductility which allows the material to deform before cracking or breaking. (more…)
When working with any steel, but in particular wear resistant steels, it is imperative that you know the grain direction of the plate.
A steel plate’s grain direction comes from the mill’s rolling process, which stretches the metallurgical structure of the material. The grains run parallel to the rolling direction. (more…)
