9cr-1Mo steel properties
9cr-1Mo steel properties
(OP)
What is the difference between ASTM A387 grade 9 class 1 and class 2. Is it only in tensile properties? Class 2 is having higher tensile strength, does that mean it is having finer grains and less creep strength(Operating temperature 500 C) compared to class 1?
Thanks in advance
