Note: 1. Tensile Properties given in brackets are for guidance only and are not mandatory unless specially agreed at the     time of ordering. Tensile test result is not normally requested for grade CR 3 and 2. For material less then 1.00 mm thick, the percentage elongation is reduced by 1 for each 0.25mm reduction in     thickness. 3  In case of this specification the agreement between the manufacturer and the customer is prior to ordering . 4. *t- thickness of material
