AISI 316 Stainless Steel vs. Tungsten Carbide
AISI 316 stainless steel and tungsten carbide belong to fundamentally different material chemistries. AISI 316 stainless 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 14 material properties with values for both materials. Properties with values for just one material (27, in this case) are not shown.
For each property being compared, the top bar is AISI 316 stainless steel and the bottom bar is tungsten carbide.
