Metal stamping parts stiffness, strength and hardness of explanation - - precision

Metal stamping parts stiffness, strength and hardness are the material mechanics performance indicators, in order to understand the meaning of the three, we first need to know: elastic deformation: when the external force are removed to restore to its original shape and size of the deformation. After plastic deformation, when the external force to remove cannot restore to its original shape and size of the deformation. Next, understand the stiffness, strength and hardness, it is easier to: stiffness: metal materials in stress resistance to elastic deformation. Strength: metal materials under the action of external force's ability to resist plastic deformation and fracture. Hardness: metal material's ability to fight more hard objects into them. Is no necessary link between, hardness is a comprehensive mechanical performance index, general high hardness material, its strength is high. Metal materials under the action of external force called ability to resist permanent deformation and fracture strength. According to the nature of the external force mainly include the yield strength, tensile strength, compressive strength, bending strength, etc. , engineering commonly used is the yield strength and tensile strength, strength of these two indicators can be measured through tensile test. Strength: refers to the metal stamping resistance before and after the load bearing fracture or exceed the allowable limit of residual deformation ability. That is to say, the strength is one of the important indicators measure parts itself bearing capacity, was first shall meet the basic requirements of mechanical parts. Strength test research is a comprehensive research, mainly through its stress state to study the stress of the parts, and predict failure conditions and timing of destruction. Hardness: is it a material's ability to fight hard pushed to the surface. Indicators, it can be understood as the material the ability of resistance to elastic deformation and plastic deformation or damage, can also be expressed as the material's ability to fight the residual deformation and failure. Hardness is not a simple physical concept, but the material mechanical properties such as elasticity, plasticity, strength and toughness of the composite indicator. Hardness test according to the different test methods can be divided into static pressure method to scratch method, rebound method and microhardness, a variety of methods such as high hardness. Stiffness: refers to the metal stamping resistance to elastic deformation under load. The stiffness of common unit deformation of the required force or moment, stiffness depends on the size of the components of the geometry and material types.
