GB L53451 GB/T 4171 Mechanical Properties
The tensile strength of GB L53451 GB/T 4171 steel is between 570 and 700MPa. The yield strength of this steel is min 195MPa and the elongation after fracture is approximately 12%. The test value of lateral expansion of steel goes up to 22%. The notch impact energy of GB/T 4171 steel plates can reach 34J. The cold bending performance of the steel plates is satisfactory, with the bend radius greater than 4 times the width of the steel plates.
Introduction of mechanical properties GB L53451 GB/T 4171:
Yield point(σs)When the stress of GB L53451 GB/T 4171 or specimen exceeds the elastic limit in tension, even if the stress does not increase, the GB L53451 GB/T 4171 or specimen will continue to undergo obvious plastic deformation. This phenomenon is called yielding, and the minimum stress value when yielding occurs is called yield point.
Tensile Strength(σb) : The maximum stress of GB L53451 GB/T 4171 during tension from the beginning to the time of fracture. It indicates the ability of GB L53451 GB/T 4171 to resist fracture.
Elongation(δs) : The percentage of the plastic elongation length to the original sample length is called elongation.
Yield-strength ratio(σs/σb) : The ratio of yield point (yield strength) to tensile strength of GB L53451 GB/T 4171 is called its yield strength ratio. The greater the yield-strength ratio, the higher the reliability of structural parts.
Hardness: Hardness is the ability of GB L53451 GB/T 4171 to resist hard objects pressing into its surface. The higher the hardness, the better the wear resistance.
