Galvanised Steel Sheet Properties

Gi takes place on a cold rolled plate and gi h takes place on a hot rolled plate.

Galvanised steel sheet properties.

Alloyed coating a 25. Single spot test both sides. 1 t bends in many of the steels were embrittled by galvanizing but galvanized 2 t and 3 t bends in all steels could be completely straightened without cracking. Typical of astm steel.

Thus the tensile strength proof strength and tensile elongation of cold rolled steel were unaffected except that the tensile elongation of 40 cold rolled steel tended to be increased by galvanizing. Galvanized steel is produced by coating the steel in zinc. 80mm min 1 5 2 014 16 elongation min 23 elongation at break 2 0 2 515 17 brinnel scale kg mm 95 125 elongation at break 2 5 3 016 18 reference standards reference standards. While molten zinc solidifies on the surface of the steel sheet normal zinc crystallization is suppressed creating fine crystals.

The zinc protects the base metal by acting as a barrier to corrosive elements and the sacrificial nature of the coating results in a long lasting and high quality steel product. Properties of galvanized steel.
