L0--試樣原始標(biāo)距長度，mm。斷面收縮率：(ψ)在拉伸試驗(yàn)中，試樣拉斷后其縮徑處橫截面積的縮減量與原始橫截面積的百分比，稱為斷面收縮率。以ψ表示，單位為%。式中：S0--試樣原始橫截面積，mm2; S1--試樣拉斷后縮徑處的少橫截面積，mm2。硬度指標(biāo) ：金屬材料抵抗硬的物體壓陷表面的能力，稱為硬度。根據(jù)試驗(yàn)方法和適用范圍不同，硬度又可分為布氏硬度、洛氏硬度、維氏硬度、肖氏硬度、顯微硬度和高溫硬度等。對于管材一般常用的有布氏、洛氏、維氏硬度三種。布氏硬度(HB)：用一定直徑的鋼球或硬質(zhì)合金球，以規(guī)定的試驗(yàn)力(F)壓入式樣表面，經(jīng)規(guī)定保持時(shí)間后卸除試驗(yàn)力，測量試樣表面的壓痕直徑(L)。布氏硬度值是以試驗(yàn)力除以壓痕球形表面積所得的商。以HBS(鋼球)表示，單位為N/mm2(MPa)。</div><p><img
