鍛圓是經(jīng)過工藝要求鍛造的圓鋼。規(guī)格國內(nèi)一般生產(chǎn)可以達(dá)到1500mm直徑。鍛材是鍛壓的是沖擊力，適合小的零部件或異型鋼加工。

圓鋼是指截面為圓形的實心長條鋼材。其規(guī)格以直徑的毫米數(shù)表示，如“ 50”即表示直徑為 50毫米的圓鋼。

圓鋼分為熱軋、鍛制和冷拉三種。熱軋圓鋼的規(guī)格為5.5-250毫米。其中：5.5-25毫米的小圓鋼大多以直條成捆供應(yīng)，常用作鋼筋、螺栓及各種機(jī)械零件；大于25毫米的圓鋼，主要用于制造機(jī)械零件或作無縫鋼管坯。

45#圓鋼是指截面為圓形的實心長條鋼材。其規(guī)格以直徑的毫米數(shù)表示，如“ 50”即表示直徑為 50毫米的圓鋼。

45#圓鋼分為熱軋、鍛制和冷拉三種。熱軋圓鋼的規(guī)格為5.5-250毫米。其中：5.5-25毫米的小圓鋼大多以直條成捆供應(yīng)，常用作鋼筋、螺栓及各種機(jī)械零件；大于25毫米的圓鋼，主要用于制造機(jī)械零件或作無縫鋼管坯。

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.
