对于拉伸试验的取样
是否同一批号的钢板对于吨位大于50吨的要取两组试样？
是否对于同一批号的两个板厚差大于9.5mm时必须取两组试样不管吨位的大小
以下是在规范中看到的希望英语高手解答下
One tension test is to be made on two different plates, shapes or bars from each heat of steel, unless the
finished material from a heat is less than 50 tons, when one tension test will be sufficient. If, however,
material from one heat differs 9.5 mm (0.375 in.) or more in thickness or diameter, one tension test is to be
made from both the thickest and the thinnest material rolled, regardless of the weight represented. |
