    在建筑工程中,圓鋼和螺紋鋼是對不同種類鋼筋的通俗叫法,今天圓鋼廠家給大家講解一下它們的不同。它們之間的不同主要有以下五點:

    In the construction project, the round steel and the screw steel are popular methods for different kinds of steel. Today, the yuan steel manufacturers explain their differences. The differences between them mainly include the following five points:

    1.外形不同。圓鋼的外表面是光滑的;螺紋鋼的外表面帶有螺旋形的肋。

    1. the shape is different. The outer surface of the round steel is smooth; the outer surface of the screw steel has a spiral rib.

    2.強度不同。圓鋼的設計強度為210MPa;螺紋鋼的強度較圓鋼要高,HRB335的設計強度為300MPa;HRB400的設計強度為360MPa。

    The 2. intensity is different. The design strength of the round steel is 210MPa; the strength of the screw steel is higher than that of the round steel, the design strength of HRB335 is 300MPa, and the design strength of HRB400 is 360MPa.

    3.生產標準不同?,F行標準中,圓鋼指HPB235級鋼筋,螺紋鋼一般指HRB335及HRB400級鋼筋,它的生產標準是鋼筋混凝土用熱軋帶肋鋼筋。

    3. the standard of production is different. The current standard in the round, refers to the HPB235 grade steel, rebar generally refers to HRB335 and HRB400 grade steel, its production is standard hot rolled ribbed steel reinforced concrete.

    4.鋼種不同,即化學成份不同。圓鋼屬碳素鋼,鋼種是Q235;螺紋鋼屬低合金鋼,HRB335級鋼筋是20錳硅;HRB400級鋼筋是20MnSiV或20MnSiNb或20MnTi等。

    4. the steel is different, that is, the chemical composition is different. Round steel is carbon steel, steel is Q235; screw steel is low alloy steel, HRB335 grade steel is 20 manganese silicon; HRB400 grade steel is 20MnSiV or 20MnSiNb or 20MnTi and so on.

    5.物理力學性能不同。濟鋼代理商由于鋼筋的化學成份和強度的不同,因此在物理力學性能方面有所不同。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;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、抗疲勞性能方面較圓鋼好。

    5. the physical and mechanical properties are different. The agents of Jigang are different in physical and mechanical properties because of the difference in the chemical composition and strength of the steel. The cold bending property of round steel is better. It can make 180 degree crooked hooks. Threaded steel can only be used as a straight hook with a degree of 90 degrees. The weldability of round steel is better than that of ordinary carbon electrode. The low alloy welding rod should be used for threaded steel, and the toughness and fatigue resistance of threaded steel is better than that of round steel.
