45# what are the main rounds for?

Answer:

45# round steel refers to the cross section of round solid steel. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter
High quality carbon structural steel can be used in many and many structural steels. It is widely used and can be used as long as it does not involve corrosion, or too high strength and toughness
45# round bars are divided into three kinds: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of them: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
