style="text-indent:25px">硬度是衡量金屬材料軟硬程度的指針。目前生產(chǎn)中測定硬度方法常用的是壓入硬度法，它是用一定幾何形狀的壓頭在一定載荷下壓入被測試的金屬材料表面，根據(jù)被壓入程度來測定其硬度值。常用的方法有布氏硬度（HB）、洛氏硬度（HRA、HRB、HRC）和維氏硬度（HV）等方法，廣州方管規(guī)格，廣州方管規(guī)格。疲勞前面所討論的強(qiáng)度、塑性，廣州方管規(guī)格、硬度都是金屬在靜載荷作用下的機(jī)械性能指針。實際上，許多機(jī)器零件都是在循環(huán)載荷下工作的，在這種條件下零件會產(chǎn)生疲勞。沖擊韌性以很大速度作用于機(jī)件上的載荷稱為沖擊載荷，金屬在沖擊載荷作用下抵抗破壞的能力叫做沖擊韌性。方管按壁厚分類：超厚壁方管、厚壁方管和薄壁方管。廣州方管規(guī)格</p><div
