["밸브의 선택", "고온 55555555555552225555525555℃, 고압 51550kg의 고압 용기에 적합한 밸드 소재는 무엇이나요. 용기 내부는 광물분말이 H8g/l의 H H硫酸存在。国内是否有这方面的经验或者使用过的同行， "국내에서 이런 밸드를 만드는 제조업체는 어떨가요", "이런 종류의 밸브는 2517소재를 사용해 보았나요.이 소재는 쓰임이还好" "미세상태 분해가 유연성 변화를 유발하여 이방성강의 사용 온도를 제한합니다", "이 특수 조건에서는 여전에进口的可能更好，这样会更放心"]

在高温255℃，高压50公斤，高压容器上使用什么材质的球阀比较好。高容器内为矿浆含H2SO4 28g/l。国内有没有这方面经验，或者使用过的同行，介绍一下

国内做这方面阀门的厂家多吗

这类的阀门有用过2507材质的，使用情况还好，一方面这类不锈钢可以耐腐蚀，另一方面可以耐高温

亚稳态分解引起脆变并限制双相钢的使用温度

此特殊工况，还是选进口的吧，比较放心
