在建筑工程中,圆钢和螺纹钢是对不同种类钢筋的通俗叫法,今天圆钢厂家给大家讲解一下它们的不同。它们之间的不同主要有以下五点:

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。圆钢的外表面是光滑的;螺纹钢的外表面带有螺旋形的肋。

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.强度不同。圆钢的设计强度为210MPa;螺纹钢的强度较圆钢要高,HRB335的设计强度为300MPa;HRB400的设计强度为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.生产标准不同。现行标准中,圆钢指HPB235级钢筋,螺纹钢一般指HRB335及HRB400级钢筋,它的生产标准是钢筋混凝土用热轧带肋钢筋。

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.钢种不同,即化学成份不同。圆钢属碳素钢,钢种是Q235;螺纹钢属低合金钢,HRB335级钢筋是20锰硅;HRB400级钢筋是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.物理力学性能不同。济钢代理商由于钢筋的化学成份和强度的不同,因此在物理力学性能方面有所不同。圆钢的冷弯性能较好,可以作180度的弯钩,螺纹钢只能作90度的直钩;圆钢的可焊性较好,用普通碳素焊条即可,螺纹钢须用低合金焊条;螺纹钢在韧性、抗疲劳性能方面较圆钢好。

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.
