Round bar Steel 4140 Cold Drawn Carbon Steel Bars

Application scope Round steel has broad application prospects and is widely used in hardware, construction, automotive, shipbuilding, petrochemicals, machinery, medicine, food, electricity, energy, aerospace, and building decoration. The most extensive processing of ordinary mechanical parts, including general rod steel parts, CD rods, bolts, and nuts. Material grade 10 #, 20 #, 35 #, 45 #, Q215, Q235, 304, 316, 20Cr, 40Cr, 20CrM o, 35CrMo, 42CrMo, 40CrNiMo, GCr15, 65Mn, 50Mn, 50Cr, 3Cr2W8 V,20CrMnTi, 5CrMnMo The difference between round steel and other steel bars: 1. The appearance is different. Round steel has a smooth and round shape, without lines or ribs, while other steel bars have grooves or ribs on their surface. This results in a low bonding force between round steel and concrete, while other steel bars have a high bonding force with concrete. 2. The composition is different. Round steel (first grade steel) belongs to ordinary low-carbon steel, while other steel bars are mostly alloy steel. 3. The strength is different. Round steel has lower strength, while other steel has higher strength. That is, compared to other steel bars with the same diameter, round steel can withstand less tensile force, but its plasticity is stronger. That is, round steel has greater deformation before being pulled apart, while other steel bars have much smaller deformation before being pulled apart.
