4.鋼種不同，(化學(xué)成份不同)。不銹鋼圓鋼(HPB235)屬碳素鋼，鋼種是Q235；螺紋鋼屬低合金鋼，HRB335級鋼筋是20MnSi(20錳硅)；HRB400級鋼筋是20MnSiV或20MnSiNb或20MnTi等； </p> <p> <br /> </p> <p> 5.物理力學(xué)性能不同。由于鋼筋的化學(xué)成份和強度的不同，因此在物理力學(xué)性能方面有所不同。不銹鋼圓鋼的冷彎性能較好，可以作180度的彎鉤，螺紋鋼只能作90度的直鉤；不銹鋼圓鋼的可焊性較好，用普通碳素焊條即可，螺紋鋼須用低合金焊條；螺紋鋼在韌性、抗疲勞性能方面較不銹鋼圓鋼好。螺紋鋼一般用于鋼筋混凝土設(shè)施的建造，他的材質(zhì)一般是低合金鋼牌號一般是16Mn(16錳低合金鋼)，或著45號碳結(jié)剛，它們的屈服強度都在350Mpa以上，抗拉強度都在500Mpa上下，比普通的低碳鋼不銹鋼圓鋼高出很多(經(jīng)過熱處理的螺紋鋼強度可比低碳不銹鋼圓鋼高出近一倍甚至更高)。由于表面具有螺紋形狀，可以加大與混凝土的牢固粘合?；炷翗?gòu)件用縱筋、箍筋等均應(yīng)優(yōu)先選擇使用螺紋鋼。 </p> <p> <br /> </p> <p> <br /> </p><p style="text-indent:25px">煉時加入的合金元素不同，也就有了磁鐵吸得上與吸不上的區(qū)別了。不銹鋼一般是按組織結(jié)構(gòu)分的，可以分為奧氏體、鐵素體、馬氏體等幾大類。如果往鋼水里加入了不同比例的鉻鎳等，煉成的奧氏體鋼就是磁鐵吸不上的不銹鋼；如果往鋼水里加入鉻和少量鎳（或不加鎳），煉成的鋼就是磁鐵吸得上的不銹鋼，也叫鐵素體不銹鋼；馬氏體不銹鋼主要合金元素是鉻、鐵和碳。不銹鋼因含合金量不同分有100多種。除了奧氏體不銹鋼磁鐵吸不上外，鐵素體、馬氏體不銹鋼都具有磁性。螺紋鋼的強度較不銹鋼圓鋼要高，HRB335的設(shè)計強度為300MPa。</p><div
