锻圆是经过工艺要求锻造的圆钢。规格国内一般生产可以达到1500mm直径。锻材是锻压的是冲击力，适合小的零部件或异型钢加工。

圆钢是指截面为圆形的实心长条钢材。其规格以直径的毫米数表示，如“ 50”即表示直径为 50毫米的圆钢。

圆钢分为热轧、锻制和冷拉三种。热轧圆钢的规格为5.5-250毫米。其中：5.5-25毫米的小圆钢大多以直条成捆供应，常用作钢筋、螺栓及各种机械零件；大于25毫米的圆钢，主要用于制造机械零件或作无缝钢管坯。

45#圆钢是指截面为圆形的实心长条钢材。其规格以直径的毫米数表示，如“ 50”即表示直径为 50毫米的圆钢。

Forged round is a round steel that has been forged by the process. Specifications domestic general production can reach 1500mm diameter. Forgings are forged and impact, suitable for small parts or profiled steel.

Round steel is a solid strip of steel with a circular cross section. The specifications are expressed in millimeters of diameter. For example, "50" means a round steel with a diameter of 50 mm.

Round steel is divided into hot rolling, forging and cold drawing. Hot rolled round bars are available in sizes from 5.5 to 250 mm. Among them: small round steels of 5.5-25 mm are mostly supplied in straight strips, often used as steel bars, bolts and various mechanical parts; round steels larger than 25 mm are mainly used for manufacturing mechanical parts or seamless steel tube blanks.
