Round steel, what we usually call round steel refers to a solid long steel with a circular cross-section. What is its classification and what are its characteristics?Let me introduce you:
Round steel is divided into three types: hot rolled, forged and cold drawn.The difference between round steel and other steel bars is:
1. The shape of the round steel is different. The round steel has a smooth shape, no grains and no ribs. The surface of other steel bars is carved or ribbed, which will cause the bonding of the round steel and concrete to be small, while the adhesion of other steel bars to concrete is small. The knot is strong.
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 low strength, and other steels have high strength, that is, round steel with the same diameter is compared with other steel bars, and the tensile force of round steel is smaller than other steel bars, but the plasticity of round steel is stronger than other steel bars. , That is, the round steel has a larger deformation before being broken, and the deformation of other steel bars is much smaller before being broken.
There is also a steel casting, which is characterized by poor fluidity, large body shrinkage, line shrinkage and crack sensitivity, high comprehensive mechanical properties, compressive strength and tensile strength almost equal, and poor vibration absorption.
Round steel has broad application prospects and is widely used in hardware, construction, automobiles, shipbuilding, petrochemicals, machinery, medicine, food, electricity, energy, aerospace, etc., and building decoration.Under normal circumstances, Ever-Power couplings are made of 45# steel, and can also be made according to customer requirements if required.
