Difference between Annealing and Tempering The difference between annealing and tempering is determined by how it is treated. Tempering the metal entails heating it to a certain heat below a certain threshold and then cooling it at a very slow and regulated rate, while annealing involves heating the metal to a given temperature and then cooling [...]
What Is the Difference Between a Round Bar, a Drill Rod, and a Shafting? Metals are made in different shapes and sizes. Pipe and tubes look similar but somewhat different properties and use. Round bar, drill rod, and shafting are also forms of round shapes. Round Bar A round bar is a long, cylindrical metal [...]
All you need to know about The Melting Points of Metals Metals have prestige for being able to survive harsh environments. Heavy loads, continuous cycling, major intensity, caustic conditions, and even extreme temperatures are all factors to consider. Furnaces, diesel motors, piston engines, spark nozzles, high-speed machines, and exhaust systems are all exposed to conditions that [...]
How does heating the metal affects its properties? Heat can affect the electrical, magnetic, and structural properties of metals. Since metal has a wide range of uses, various conditions emphasize different attributes. Toughness is required in industrial applications, whereas low electrical density is significant in electronic applications. There are many methods of heating metal that are [...]
WHAT IS CREEP? Creep is a topic in metallurgy that can be quite confusing; while not common knowledge to many people, the subject of creep is one that those in charge of selecting metals must be aware of. Creep is a type of deformation, and metals that undergo excessive creep deformation can oftentimes fail completely. Unfortunately, [...]
WELDING PROCESSES FOR STAINLESS STEEL Warped metal, charcoal-colored welds, and frustration; these are some of the things that can happen when welding stainless steel. While it contains similar elements to that of carbon steel, stainless steel has the addition of alloying elements such as chromium and molybdenum, and that presents an altogether different set of challenges [...]
WHAT IS A FERROUS METAL? There are many different categories into which metals can be placed. Some metals may be ductile, some may be brittle. Other metals could be magnetic, and some have no magnetism at all. Some types of alloys can be precipitation hardened, and others cannot. The aforementioned are important distinctions; however, when categorizing [...]
WHAT IS QUENCHING? Heat treatment is a popular way to alter the mechanical properties of certain metals. Being able to change the hardness, toughness, and strength of a metal while keeping its chemical composition intact and virtually unaltered is a great way to tailor a metal to the needs of the environment and the demands of [...]
PIPE SCHEDULE CHART When working with pipe, it is common to describe them by their “schedule”. Someone unfamiliar with pipe schedules may not understand how to determine the measurements. A pipe schedule is a non-dimensional number that relates to the thickness of the wall and affects the inside diameter. It is used to help classify pipes [...]
WHAT IS NORMALIZING? It is important that the material used for any project possesses the correct mechanical properties for the specific application. Heat Treatment processes are often used to alter the mechanical properties of a metal, with one of the more common heat treatment processes being Normalizing. What Is Normalizing? Normalizing is a heat treatment [...]
