中低合金钢标样成份组合的一般情况对高合金钢而言,总是针对某一钢号,制备一套标样,此时一般不需要考虑标样的通用性(即一套标样可以同时分拆多种钢号的样品)。对于品种繁多的中低合金钢,不能为每个钢号都设置一套标样,因此在制备和使用标样时,都要考虑“第三元素”的影响 Low-alloy steel standard composition of the general situation High alloyed steel, always against a steel, prepare a set of standard, this time generally do not need to consider the standard of versatility (that is, a set of standard can At the same time split a variety of steel samples). For a wide variety of low-alloy steel, you can not set a standard for each steel standard, so in the preparation and use of standard, we must consider the “third element” effect
