镍铬钢之性能,完全决定于它自身所含之炭量(如含镍、铬量一定时);因之我们要竭力发展控制其含炭量之科学方法。于是很多研究者就用了各种各样的氧化剂,在高炭络镍钢中进行了不少次数的试验。这一种方法,已渐渐可能成为工业上大量生产之用。被试验之金属,是在一个内面涂以齡性耐火材料之坩锅中熔化,而以高度氧化性之渣处理之。处理的结果告诉我们,氧化镍铬钢(像KA2合金)中之炭份,比氧化普通钢(Straight steel)中之炭份困难得多。这也就说明在上述二种金属中,炭之存在状况有所不同。在高镍、低铬之台金钢中,如Nichrome(注一)合金中之炭,可以
The performance of NiCr steel depends entirely on the amount of carbon it contains (eg nickel and chromium); therefore, we must strive to develop a scientific method of controlling its carbon content. As a result, many researchers used a wide variety of oxidants and performed many tests in high carbon steel nickel steels. This method has gradually become possible for mass production in industry. The metal to be tested is melted in a crucible coated with an internal refractory material and treated with a highly oxidizing slag. The results of the treatment tell us that the carbon content in nickel chromium chrome (like KA2 alloy) is much more difficult than oxidizing carbon in normal steel. This also shows that in the two metals, the presence of carbon is different. In high-nickel, low-chromium steels, such as Nichrome’s carbon, you can
