注Note:
① 强度和延伸率不在质保书中体现;
The value will not be reported on the test certificate.
② -40℃横向冲击，3点平均值，单值不小于最小平均值的70%；厚度小于12mm采用小尺寸式样，最小平均值正比例于试样横截面积。
Lmpact test at -40℃,transverse to the rolling direction; Charpy test average of three values,single value min 70% of apecified average; For plate thicknesses under 12mm subsize Charpy V-specimens are used, the specified minimum value is then proportional to the specimens cross-section.
③ 硬度为表面硬度 Surface hardness as hardness value.
