Grade 300 Maraging Steel vs. Tungsten Carbide
Grade 300 maraging steel and tungsten carbide belong to fundamentally different material chemistries. Grade 300 maraging steel is a metal, while tungsten carbide is a ceramic material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 12 material properties with values for both materials. Properties with values for just one material (21, in this case) are not shown.
For each property being compared, the top bar is grade 300 maraging steel and the bottom bar is tungsten carbide.
