SGC570 cold rolled galvanized steel sheet,SGc570 hot dip galvanized steel plate,SGC570 galvanized steel coil owned the highest tensile strength at above 570 Mpa among galvanized steel grades in steel standard JIS G3302.galvanized steel sheet SGC570 contains max 0.30,this cause its higher tensile strength when rolling.
Hot-dip galvanized steel plate and coil sgc570 is for extra deep drawing quality.After rolled,Chemical passivation for sgc570 is chosed by customers,Chemical passivation protects the surface against humidity and reduces the risk of formation of white rust during transportation and storage in open yard.Local discolouring as a result of this treatment is permissible and does not impair the quality for galvanized steel SGC 570.
Introduction of mechanical properties JIS SGC 570 JIS G3302:
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.
