- Q: What is the difference between a rough turned and a seamless steel round bar?
- A rough turned steel round bar is a metal bar that has undergone a preliminary turning process to achieve a rougher surface finish. This process removes excess material and helps create a more uniform diameter by eliminating surface imperfections or irregularities. Rough turned bars are commonly used in applications where a smooth surface finish is not necessary, such as in the manufacturing of machinery or agricultural equipment. On the other hand, a seamless steel round bar is a solid metal bar that is formed without any welding or seams. It is manufactured through a process called piercing, where a solid billet is heated and pierced with a mandrel to create a hollow tube. The tube is then elongated and reduced in diameter through rolling and drawing processes until it reaches the desired dimensions. Seamless round bars are known for their superior strength and resistance to corrosion, making them suitable for applications that require high performance, such as in the oil and gas industry or automotive manufacturing. To summarize, the main distinction between a rough turned and a seamless steel round bar lies in their manufacturing processes and surface finishes. Rough turned bars are created by removing excess material to achieve a rougher surface finish, while seamless bars are formed without any welding or seams, resulting in a smooth and continuous surface.
