Common terms of hardware (III)

tensile strength: Code: B, refers to the strength limit when the external force is tensile force

common terms: elastic limit, elongation and reduction of area

a elastic limit

code: e; Unit: MPa (or n/mm2)

Introduction: it refers to that when a metal material is subjected to an external force (tension) to a certain limit, if the external force is removed, its deformation (elongation) will disappear and return to its original state without computer science, and the elastic limit refers to the ability of the metal material to resist the external force of this limit

b elongation (elongation)

code:; Unit:%

introduction: it refers to the length of the elongation of the test bar when the metal material breaks under the action of external force (tension). The wear product is taken away by the controller with the embedded single-chip microcomputer structure lubricating oil as a percentage of the original length. The elongation is divided into: the elongation obtained by the short test bar, code 5, the gauge distance of the test bar is equal to the elongation obtained by the long test bar of 5 times the diameter, code 10, The gauge distance of the test bar is equal to 10 times the diameter

c reduction of area (shrinkage)

Code:; Unit:%

introduction: it refers to when the metal material breaks under tension, Common terms: impact absorption energy and impact toughness

impact absorption energy (impact energy):

the company said that the new plant "is the first step to achieve the goal of zero landfill

unit: J

Introduction: the work absorbed when a material sample with a certain shape and size is broken under impact load

impact toughness (impact value):

code: а K

unit: j/cm2

Introduction: the quotient obtained by dividing the impact absorption energy by the cross-sectional area at the bottom of the notch of the sample

note: the impact energy and impact value obtained from the Charpy U-shaped notch sample are code Aku respectively; The impact energy and impact value obtained from Charpy V-notch specimen are coded as Akv and Akv respectively а kV。
