What are the main considerations when choosing mechanical parts?
Mechanical parts are designed to select the material to take into account factors: the function of the part, the part of the device, its purpose.
Heat treatment conditions, there is no heat treatment conditions and no heat treatment conditions of the election of different materials; the weight requirements, often mentioned in the hands of the parts require light, to meet the mechanical strength conditions can choose a small proportion of material, life requirements
The load of the part determines the grade of the material according to the load or according to the strength requirements.
The impact of ambient temperature, changes in ambient temperature will affect the expansion and contraction of parts; parts of the surface quality requirements and corrosion requirements; cost factors;
