style="text-indent:25px">鋼筋的機械性能通過試驗來測定，微量鋼筋質(zhì)量標準的機械性能有屈服點、抗拉強度、伸長率，冷彎性能等指標。1、屈服點(fy)當鋼筋的應力超過屈服點以后，拉力不增加而變形卻明顯增，加，將產(chǎn)生較大的殘余變形時，以這時的拉力值除以鋼筋的截面積所得到的鋼筋單位面積所承擔的拉力值，就是屈服點σ5。2、抗拉強度(f)抗拉強度就是鋼筋被拉斷前所能承擔的比較大拉力值除以鋼筋截面積得的拉力值，抗拉強度又稱為極限強度。它是應力——應變曲線中比較大的應力值，是鋼筋機械性能中必不可少的保證項目。因為:抗拉強度是鋼筋在承受靜力荷載的極限能力，可以表示鋼筋在達到屈服點以后還有多少強度儲備，是抵抗塑性破壞的重要指標。矩管的生產(chǎn)方式主要有兩種，即是有冷軋和熱軋兩種方式。</p><div
