Verification regulation of high - temperature creep and stress - rupture testing machine 高温蠕变持久强度试验机检定规程
The proper processing , which is difficult , can assure the final acceptable proportion microstructure ( fig . 1 ) and the expected high - temperature creep strength 正确的工艺过程(是很难实现的) ,可以保证最后能被接受的均衡微观结构和所期待的高温蠕变强度。
This kind of steel is a casting material of p91 , with the better performances of high temperature anti - oxidation , high - temperature creep rupture strength , t hermal conductivity and the lower performances of t hermal expansion . there is no casting in chinese 该钢种为p91对应的铸材牌号,材料具有良好的高温抗氧化性能,较高的高温蠕变强度、持久强度和韧性,低的热膨胀性,良好的导热性、加工性等特点。
