Grade 350 Maraging Steel vs. Zinc Sulfide

Grade 350 maraging steel and zinc sulfide belong to fundamentally different material chemistries. Grade 350 maraging steel is a metal, while zinc sulfide is a ceramic material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 8 material properties with values for both materials. Properties with values for just one material (22, in this case) are not shown.

For each property being compared, the top bar is grade 350 maraging steel and the bottom bar is zinc sulfide.
