二級(jí)螺紋鋼和三級(jí)螺紋鋼的區(qū)別（不同點(diǎn)）首先我們帶大家了解一下什么是二級(jí)螺紋鋼，什么是三級(jí)螺紋鋼。二級(jí)螺紋鋼：即新標(biāo)準(zhǔn)名稱為HRB335的鋼筋，二級(jí)螺紋鋼為舊稱，為熱軋帶肋鋼筋的一種。螺紋鋼在建筑業(yè)中，Ⅱ級(jí)螺紋鋼和Ⅲ級(jí)螺紋鋼是過去的叫法，新標(biāo)準(zhǔn)中，Ⅱ級(jí)螺紋鋼稱為HRB335。普遍用于房屋、橋梁、道路等土建工程建設(shè)。三級(jí)螺紋鋼：即新標(biāo)準(zhǔn)名稱為HRB400的鋼筋，三級(jí)螺紋鋼為舊稱，為熱軋帶肋鋼筋的一種。在建筑業(yè)中，三級(jí)螺紋鋼是過去的叫法。熱軋帶肋鋼筋的牌號(hào)由HRB和牌號(hào)的屈服點(diǎn)最小值構(gòu)成。H、R、B分別為熱軋（Hotrolled）、帶肋（Ribbed）、鋼筋（Bars）三個(gè)詞的英文首位字母。其實(shí)從定義上我們只能看出二級(jí)螺紋鋼和三級(jí)螺紋鋼只是在材質(zhì)上有所不同，一個(gè)是hrb335，一個(gè)是hrb400。反而從定義上我們更多的是可以看出兩者的相同點(diǎn)，都屬于普通低合金熱軋鋼筋；都屬于帶肋鋼筋（即通常說的螺紋鋼筋）；都可以用于普通鋼筋混凝土結(jié)構(gòu)工程中。既然這樣我們就仔細(xì)的來分析一下二級(jí)螺紋鋼和三級(jí)螺紋鋼的區(qū)別與不同點(diǎn)：1、鋼種不同，（化學(xué)成份不同）。HRB335級(jí)鋼筋是20MnSi(20錳硅)；HRB400級(jí)鋼筋是20MnSiV或20MnSiNb或20MnTi等；2.強(qiáng)度不同。烏魯木齊本地螺紋鋼新疆用戶注意！螺紋鋼大量現(xiàn)貨供應(yīng)！你還猶豫什么呢？</p><div
