Hot Rolled Carbon Steel Round Bar ASTM 4140 JIS DIN 42CrMo4 C45 Cr12 Forged Solid Round Bar

Low carbon steel is easy to accept a variety of processing forging, welding and cutting, can manufacture chains, rivets, bolts, shafts and so on. Carbon content less than 0.25% carbon steel, because of its low strength and hardness and soft, it is also called soft steel. Including ordinary carbon structural steel and high-quality carbon structural steel. Low carbon steel is generally rolled into Angle steel, channel steel, I-steel, steel pipe, steel belt and steel plate, used to make a variety of building components, containers, boxes, furnace body and agricultural machinery. High-quality low carbon steel rolled into sheet, the production of car cab, engine hood and other deep drawing products; Made into bars, used to make mechanical parts with low strength requirements. Mild steel is limited in use due to its low strength. The strength of steel can be greatly improved by increasing the content of manganese in carbon steel and adding trace alloying elements such as vanadium, titanium and niobium. Using a mild steel bar, the manufacturer inserts the bar until the desired round steel pipe is formed. Welding with high frequency current. Once formed, pass the tube through a machine that corrects the deviation and cut the tube to the desired length. The mild steel pipe is then deburred and pressure tested. Finally, the tube receives hot dip galvanizing or surface painting. The ends of the mild steel pipe may be beveled and threaded with flanges. When producing lightweight vehicles, the automotive industry often uses mild steel pipes. These tubes may also be used for general framing or housing.
