A grizzly screen or deck is a simple way to separate oversized rocks before they are fed into a crushing unit that will be crushed into smaller pieces for further processing. There is a rich history behind grizzly screens, as they were first used a few hundred years ago when mining first became mechanized. Since then, grizzly screens/decks have evolved into essential equipment which enhances the automated refining operation of the modern era.
Read MoreCold air can affect your steel. Specifically, it can make it brittle, which can lead to Thermal Cracking. Steel that is ductile at room temperature may also lose that in colder temperatures so instead of bending, it may break.
Read MoreWhat Does ISO Stand for? Customers often inquire about our ISO Certification. ISO stands for “International Organization for Standardization”, despite the fact that the letters are out of sequence. The name in different languages results in different acronyms. Thus, all 164 countries (who use ISO) agreed to use the ISO designation.
Read MoreWhat Is a Waterjet Cutter?
A waterjet cutter is a versatile industrial tool that can be used to cut a wide variety of wear resistant steels and other materials such as wood and glass. The waterjet cuts through material by combining a very high-pressure jet of water with fine particles of garnet (60,000 to 90,000 psi). This combination “gouges out” or removes tiny particles of the wear resistant steel, which effectively makes the cut. Water alone with no garnet can be used to cut softer material such as wood, plastic or rubber.
Read MoreAustenite and Martensite, in steel, refers to the microstructure of steel at the atomic level. During the tempering process or cooling, Austenite is transformed into Martensite. The ideal wear resistant steel would have a combination of retained Austenite as well as some transformed Martensite.
Read MoreAll steel mills produce standard sizes of bars (i.e. flat, round, square) and plates (i.e. 48” x 96”, 96” x 240”, 120” x 288” etc.). Consequently, the fabricator must have equipment to cut the bars or plate to a size which they can use for further processing. Other than shearing, sawing, grinding or water jet, wear resistant steel is usually cut using heat to melt the material. There are 3 main processes and each has its advantages.
Read MoreIf you were given the task to develop the world’s best wear steel, how would you develop it?
Read MoreImpact 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.
Read MoreTool 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.
Read MoreThere 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.
