a: For alloy hot dipped product, the elongation minimum value can reduce 2%, r90 can reduce 0.2.
b, BH value refers to puting the sample through 2% prestrain on the temperature 170C 土5C, keeping 20 minutes, then doing tensile test under the indoor temperature, the added value of measured yield strength compared with the stress at the time of the sample 2% prestrain.
c: When coating weight of the two sides is more than 180g/m2, the bending diameter adds to 1a; For difference thick coating products, thick coating surface as the outer surface of the bending test.
