性能（1）強(qiáng)度：一般其的屈服強(qiáng)度在300MPa以上；（2）高韌性：要求延伸率為15%～20%，室溫沖擊韌性大于600kJ/m～800kJ/m。對(duì)于大型焊接構(gòu)件，還要求有較高的斷裂韌性；（3）良好的焊接性能和冷成型性能；（4）低的冷脆轉(zhuǎn)變溫度；（5）良好的耐蝕性。成分（1）低碳：由于韌性、焊接性和冷成形性能的要求高，其碳含量不超過0.20%；（2）加入以錳為主的合金元素；（3）加入鈮、鈦或釩等輔加元素：少量的鈮、鈦或釩在鋼中形成細(xì)碳化物或碳氮化物，有利于獲得細(xì)小的鐵素體晶粒和提高鋼的強(qiáng)度和韌性；此外，加入少量銅（≤0.4%）和磷（0.1%左右）等，可提高抗腐蝕性能。加入少量稀土元素，可以脫硫、去氣，使鋼材凈化，改善韌性和工藝性能。熱處理這類鋼一般在熱軋空冷狀態(tài)下使用，不需要進(jìn)行專門的熱處理。使用狀態(tài)下的顯微組織一般為鐵素體+索氏體。用途主要用于制造橋梁、船舶、車輛、鍋爐、高壓容器、輸油輸氣管道、大型鋼結(jié)構(gòu)等。 </p><p style="text-indent:25px">螺紋鋼常用的分類方法有兩種：一是以幾何形狀分類，根據(jù)橫肋的截面形狀及肋的間距不同進(jìn)行分類或分型，如英國(guó)標(biāo)準(zhǔn)（BS4449）中，將螺紋鋼分為 Ⅰ型、Ⅱ 型。這種分類方式主要反應(yīng)螺紋鋼的握緊性能。二是以性能分類（級(jí)），例如我國(guó)現(xiàn)行執(zhí)行標(biāo)準(zhǔn)，螺紋鋼為（G B1499.2-2007）線材為1499.1-2008）中，按強(qiáng)度級(jí)別（屈服點(diǎn)/抗拉強(qiáng)度）將螺紋鋼分為3個(gè)等級(jí)；日本工業(yè)標(biāo)準(zhǔn)（JI SG3112）中，按綜合性能將螺紋鋼分為5個(gè)種類；英國(guó)標(biāo)準(zhǔn)（BS4461）中，也規(guī)定了螺紋鋼性能試驗(yàn)的若干等級(jí)。此外還可按用途對(duì)螺紋鋼進(jìn)行分類，如分為鋼筋混凝土用普通鋼筋及預(yù)應(yīng)力鋼筋混凝土用熱處理鋼筋等。江陰市港都物資有限公司可供應(yīng)品質(zhì)圓鋼歡迎咨詢。</p><div

螺紋鋼筋的成品質(zhì)量隨冶金熔煉爐次和熱軋批次的工藝情況而有所變化，爐號(hào)和批號(hào)是抽樣檢驗(yàn)的基礎(chǔ)。因此進(jìn)口收用貨部門和倉(cāng)儲(chǔ)部門要注意保留貨物上的標(biāo)記，出口企業(yè)和外貿(mào)部門也要按標(biāo)準(zhǔn)要求分清批次、爐號(hào)并提供質(zhì)量證明書。 </p> <p> 螺紋鋼一般是裸裝捆扎交貨，存放時(shí)要注意防潮，銹蝕對(duì)螺紋鋼的性能將產(chǎn)生不良影響。 </p> <p> 螺紋鋼用于房屋、橋梁、道路等土建工程建設(shè)。大到高速公路、鐵路、橋梁、涵洞、隧道、防洪、水壩等公用設(shè)施，小到房屋建筑的基礎(chǔ)、梁、柱、墻、板，螺紋鋼都是不可或缺的結(jié)構(gòu)材料。隨著中國(guó)城鎮(zhèn)化程度的不斷深入，基礎(chǔ)設(shè)施建設(shè)、房地產(chǎn)的蓬勃發(fā)展對(duì)螺紋鋼的需求強(qiáng)烈
