Mechanical design of various parts of the hardness value of how to determine?.
You send out the request and I'll help you get it! Upstairs answer obvious mistakes, such as 45 steel, the best performance in 39-44HRC, but domestic heat treatment and foreign heat treatment level there are differences, the same hardness, foreign countries are several times more durable than the domestic!
In mechanical design, you need to determine the material, strength, and wear requirements of other parts at relatively moving locations so that you can determine how to heat the parts and achieve the best hardnessIf you are testing mature products both at home and abroad, you only need to have hardness and test materials for each part
Give your reference value, heat treatment is most hard, probably 65HRC, this is the limitAnd 45 steel without heat treatment, only about 10When you design, the hardness does not require a material can be set, there are hardness requirements, then the technical requirements of hardness
