The main advantages of ST52.3 steel pipe include no oxide layer on the inner and outer walls, the ability to withstand high pressure without leakage, high precision, high smoothness, no deformation in cold bending, no cracks in flaring and flattening, etc.
ST52.3 carbon tube also has excellent mechanical properties. The yield strength reaches or exceeds 355MPa. The tensile strength is between 490 and 630MPa, and the elongation is at least 18%, showing good strength and toughness. Its performance also performed well in the impact test at 0°C.
ST52.3 Seamless Precision Steel Tubes are widely used in the manufacture of various types of engineering machinery, such as drilling rigs, excavators, loaders and other mechanical equipment and other structural parts for mining and various engineering constructions.
