Q345A無縫鋼管，Q345B無縫鋼管鋼，Q345C無縫鋼管，Q345D無縫鋼管，Q345E無縫鋼管。這是等級的區(qū)分，所代表的，主要是沖擊的溫度有所不同而矣！ Q345A級，是不做沖擊;Q345B級，是20度常溫沖擊;Q345C級，是0度沖擊;Q345D級，是－20度沖擊;Q345E級，是－40度沖擊。在不同的沖擊溫度，沖擊的數(shù)值也有所不同。不是雜質(zhì)含量。①抗拉強(qiáng)度（σb）：試樣在拉伸過程中，在拉斷時所承受的很大力（Fb），除以試樣原橫截面積（So）所得的應(yīng)力（σ），稱為抗拉強(qiáng)度（σb），單位為N/mm2（MPa）。它表示金屬材料在拉力作用下抵抗破壞的很大能力。式中：Fb--試樣拉斷時所承受的很大力，N（牛頓）； So--試樣原始橫截面積，mm2。②屈服點(diǎn)（σs）：具有屈服現(xiàn)象的金屬材料，試樣在拉伸過程中力不增加（保持恒定）仍能繼續(xù)伸長時的應(yīng)力，稱屈服點(diǎn)。若力發(fā)生下降時，則應(yīng)區(qū)分上、下屈服點(diǎn)。屈服點(diǎn)的單位為N/mm2（MPa）。上屈服點(diǎn)（σsu）：試樣發(fā)生屈服而力首次下降前的很大應(yīng)力；下屈服點(diǎn)（σsl）：當(dāng)不計(jì)初始瞬時效應(yīng)時，屈服階段中的很小應(yīng)力。式中：Fs--試樣拉伸過程中屈服力（恒定），N（牛頓）So--試樣原始橫截面積，mm2。③斷后伸長率：（σ）在拉伸試驗(yàn)中，試樣拉斷后其標(biāo)距所增加的長度與原標(biāo)距長度的百分比，稱為伸長率。以σ表示，單位為%。式中：L1--試樣拉斷后的標(biāo)距長度，mm； L0--試樣原始標(biāo)距長度，mm。④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很大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很少橫截面積，mm2。⑤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></p><div
