What are the details of the mechanical properties of 35# seamless steel pipe

The mechanical properties of 35# seamless steel pipe are as follows:

Tensile strength of 35# seamless steel pipe: Not less than 530 MPa. This indicator reflects the maximum stress that a 35# seamless steel pipe can withstand during tension, demonstrating its resistance to deformation and fracture.

Yield strength of 35# seamless steel pipe: Not less than 315 MPa. Yield strength is the stress value at which significant plastic deformation begins to occur in 35# seamless steel pipe. It is of great significance for evaluating the load-bearing capacity and safety of 35# seamless steel pipe in actual use.

Elongation of 35# seamless steel pipe: Not less than 20%. Elongation represents the percentage of total deformation of the gauge length section to the original gauge length after tensile fracture, reflecting the plastic deformation capacity of 35# seamless steel pipe.

The reduction of area (RIA) of 35# seamless steel pipe should be no less than 45%. RIA is the percentage reduction in cross-sectional area after tensile fracture, relative to the original cross-sectional area. It is an important indicator of the plasticity of 35# seamless steel pipe.

The impact energy of 35# seamless steel pipe should be no less than 55 J. Impact energy reflects the fracture resistance of 35# seamless steel pipe under impact load and is valuable for evaluating its performance under dynamic loads.

The impact toughness of 35# seamless steel pipe should be no less than 69 J/cm². Impact toughness further quantifies the toughness of 35# seamless steel pipe under impact loads.

The hardness of 35# seamless steel pipe should not exceed 197 HB in its untreated state. Hardness reflects the ability of 35# seamless steel pipe to resist localized plastic deformation and is a valuable reference for evaluating its wear resistance and service life.
