EN P 355 ML 1 EN 10028-5 Mechanical properties
Introduction of mechanical properties EN P 355 ML 1 EN 10028-5:
Yield point(σs)When the stress of EN P 355 ML 1 EN 10028-5 or specimen exceeds the elastic limit in tension, even if the stress does not increase, the EN P 355 ML 1 EN 10028-5 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 EN P 355 ML 1 EN 10028-5 during tension from the beginning to the time of fracture. It indicates the ability of EN P 355 ML 1 EN 10028-5 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 EN P 355 ML 1 EN 10028-5 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 EN P 355 ML 1 EN 10028-5 to resist hard objects pressing into its surface. The higher the hardness, the better the wear resistance.
