High Heat Resistance Galvanized Steel Coil Regular Spangle Chromated SGC 570

SGC 570 Hot Dipped Galvanized Steel Strip Zinc Coated Steel Coils

• Yield point(σs) When the stress of JIS SGC 570 JIS G3302 or specimen exceeds the elastic limit in tension, even if the stress does not increase, the JIS SGC 570 JIS G3302 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 JIS SGC 570 JIS G3302 during tension from the beginning to the time of fracture. It indicates the ability of JIS SGC 570 JIS G3302 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 JIS SGC 570 JIS G3302 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 JIS SGC 570 JIS G3302 to resist hard objects pressing into its surface. The higher the hardness, the better the wear resistance.
