8Cr14MoV Steel Vs. other knife steels
8Cr14MoV vs D2 Steel
The major difference between 8Cr14MoV steel and D2 steel is that 8Cr14MoV is stainless steel while D2 steel is regarded as semi-stainless steel. 8Cr14MoV thus majorly outshines D2 steel in corrosion and stain resistance.
D2 steel on the other hand is better than 8Cr14MoV steel in edge retention and wear resistance, it does this as it contains a higher percentage of carbon in its alloy composition.
8Cr14MoV steel is softer steel than D2 steel offers better toughness and is less likely to chip or break under tough applications. The higher toughness of 8Cr14MoV steel is comparable to AUS 8 steel and Vanadis 8 Steel.
8Cr14MoV vs 8Cr13MoV
8Cr14MoV and 8Cr13MoV are Chinese made steel almost identical in chemical composition and have same hardness, sharpness, toughness, and wear resistance. However, 8Cr14MoV contains more chromium, hence it has better corrosion resistance than 8Cr13MoV steel.
8Cr14MoV Steel vs AUS 8
8Cr14MoV is Chinese steel while AUS 8 steel is Japanese steel, hence considered high-end steel with more Carbon. More Carbon translates to better in edge retention, wear resistance, and hardness.
However, they have the same level of toughness. In terms of corrosion resistance, The AUS 8 steel has more Chromium elements in its alloy composition meaning it will offer better corrosion resistance.
Is 8Cr14MoV Steel good knife Steel?
8Cr14MoV is good knife steel in the low-budget category. It offers balanced hardness, toughness, wear resistance, edge resistance, and great corrosion resistance.
