style="text-indent:25px">不銹鋼無縫管一般常用布氏、洛氏、維氏三種硬度指標(biāo)來衡量其硬度。在不銹鋼無縫管標(biāo)準(zhǔn)中，布氏硬度用途較廣，往往以壓痕直徑來表示該材料的硬度，既直觀，又方便。但是對于較硬的或較薄的鋼材的鋼管不適用。不銹鋼無縫管洛氏硬度試驗同布氏硬度試驗一樣，都是壓痕試驗方法。不同的是，它是測量壓痕的深度。洛氏硬度試驗是當(dāng)前應(yīng)用很廣的方法，其中HRC在鋼管標(biāo)準(zhǔn)中使用僅次于布氏硬度HB。洛氏硬度可適用于測定由極軟到極硬的金屬材料，它彌補(bǔ)了布氏法的不是，較布氏法簡便，可直接從硬度機(jī)的表盤讀出硬度值。但是，由于其壓痕小，故硬度值不如布氏法準(zhǔn)確。不銹鋼無縫管310s生產(chǎn)公司不銹鋼無縫管有較高屈服強(qiáng)度和優(yōu)良耐腐蝕性能。</p><div
