Metal Working Process Performance Terminology
Metalworking is a major industry in many countries around the world, using the processes of cutting, shaping, forming, and joining of metal products. Each process requires specialized tools and techniques, as well as other specialized equipment and materials. The processes of metalworking also involve different types of stress and strain on the material, such as compression, tension, and shearing. This article will describe some common terms, related to the performance of metal working processes.
Tensile Strength: The ability of a material, when pulled in two opposite directions, to resist being pulled apart. This is measured in lbs per square inch or megapascals.
Yield Strength: The amount of force, measured in lbs or megapascals, needed to cause a material to permanently change shape or deform.
Elasticity/Elastic Modulus: The measure of how much a material can be stretched or compressed, before it remains deformed even when the force is removed. This is measured in lbs per square inch or megapascals.
Hardness: The ability to resist indentation or scratching with sharp instruments. This is commonly measured using the Rockwell A and B Scale; hardness is rated on a scale of 0 to 100, with 0 representing the softest and 100 the hardest material.
Impact Strength: The ability of a material to absorb sudden shock or strain without being broken, cracked, or otherwise damaged.
Ductility: The ability to be bent, stretched, or rolled without breaking.
Malleability: The ability of a material to be easily pressed or hammered into thin sheets or wire without cracking.
Toughness: The ability of a material to resist sudden shock or strain, as well as the ability to absorb energy during deformation.
Fatigue Strength: The amount of force or strain that a material can withstand for a given number of cycles, before it fails.
Resilience: The ability of a material to return to its original shape or size after it has been compressed, stretched, or bent.
Corrosion Resistance: The ability of a material to resist it breaking down when exposed to a corrosive environment.
Weldability: The ability to join two pieces of metal together by melting and fusing them, using either heat or pressure.
Formability: The ability of a material to be bent, extruded, stamped, or otherwise formed into finished objects without cracking or breaking.
Heat-treatability: The ability of a material to be treated with heat to alter its properties, such as hardness or strength.
Flammability: The ability of a material to burn or ignite when exposed to an open flame.
Metalworking is an important industry in many countries around the world. Each process requires specialized tools and techniques, as well as other specialized equipment and materials. The processes of metalworking involve different types of stress and strain on the material, such as compression, tension, and shearing, which can affect the performance of the material. In this article, the reader has been provided with an explanation of some of the common terms related to the performance of metalworking processes. By understanding these terms, the reader will be able to make more informed decisions when selecting the best materials and process for a particular application.
