1.力學(xué)性能（1）性能指標(biāo)：考核螺紋鋼機(jī)械性能的檢驗(yàn)項(xiàng)目包括拉伸試驗(yàn)（抗拉強(qiáng)度、屈服強(qiáng)度、延伸率）、彎曲試驗(yàn)（一次彎曲及反彎曲）。（2）檢驗(yàn)方法：①拉伸試驗(yàn)方法：常用的標(biāo)準(zhǔn)檢驗(yàn)方法有GB/、JISZ2201、JISZ2241、ASTMA370、ГОСТ1497、BS18等；②彎曲試驗(yàn)方法：常用的標(biāo)準(zhǔn)檢驗(yàn)方法有GB/T232-88、YB/T5126-2003、JISZ2248、ASTME290、ГОСТ14019等。（3）彎曲性能按規(guī)定的彎心直徑彎曲180度后，鋼筋受彎曲部位表面不得產(chǎn)生裂紋。（4）反向彎曲性能根據(jù)需方要求，鋼筋可進(jìn)行反向彎曲性能試驗(yàn)。反向彎曲試驗(yàn)的彎心直徑比彎曲試驗(yàn)相應(yīng)增加一個(gè)鋼筋直徑。先正向彎曲90度，后反向彎曲20度。經(jīng)反向彎曲試驗(yàn)后，鋼筋受彎曲部位表面不得產(chǎn)生裂紋。2.表面質(zhì)量鋼筋表面不得有裂紋、結(jié)疤和折疊。鋼筋表面允許有凸塊。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。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。伊犁高質(zhì)量花紋螺紋鋼哪家好</p><p
