Dec 09, 2019 · Alloy round steel hot rolling, forging and cold drawn three kinds. The specifications of the hot rolled round steel of 6.5 to 500mm. Among them:6.5-25 mm small alloy round steel are mostly with straight bundles of supplies, commonly used for reinforcing steel Advantages of cold drawn steel pipe ASTM A234 butt weld Cold drawn steel pipe is a kind of steel pipe, that is, it is a type classified according to different production processes,and is different from hot rolled (expanded) pipe. In the process of expanding the diameter of the capillary tube or the raw material tube, it is formed by cold drawing in multiple passes, usually on a single-chain or double-chain cold-drawing machine of 0.5 to 100T .
