当碳含量为0.10%~0.70%时,随碳量增加,Fe-Cr-Ni合金1250℃高温抗拉强度显著提高,在碳量大约为0.40%时达到峰值,而后急剧下降。同样,镍为10%和钼为0.3%时,合金1250℃高温强度最大。
When the carbon content is 0.10% ~ 0.70%, with the increase of carbon content, the tensile strength at 1250 ℃ of Fe-Cr-Ni alloy increases remarkably, reaches the peak when the carbon content is about 0.40%, and then sharp decline. Similarly, when the content of nickel is 10% and molybdenum is 0.3%, the strength of the alloy is the highest at 1250 ℃.
