Why use anything other than Grade C?
#1
The NADCA GradeC high Moly grades have higher hot tensile than H11 or H13, resist heat check  better than H11 or H13. Why does anyone use grades B,D,E,or F?

Economics. Grades B, D, E, and F are less expensive. If one of those grades will give you sufficient service life, stick with them. However, if you are having premature failure due to early severe heat check, or gross cracking....after reviewing your design and tool build standards....move to the grade C for it's higher hot tensile to improve die life. Grade C's also tend to perform better in very severe applications such as water jackets.
