If you are given two steels one is D2 steel 155wtC1200wtCr08

If you are given two steels, one is D2 steel (1.55wt%C-12.00wt%Cr-0.8wt%Mo-0.90wt%V) and another is 430F stainless steel (0.12wt%C-17wt%Cr-1.0wt%Mn-0.75wt%Ni). Which steel would you use to make a high quality knife and what process would you use to make the knife very sharp? Please give reasons for your choices.

Solution

D2 steel

Contains about 1.5% carbon and also has chromium and molybdenum added .

430F stainless steel

carbon steel with added chromium to resist corrosion and other elements which increase performance levels but usually at the expense of inferior toughness.

That\'s why 430 F stainless steel is used because it is light in weight and give sharp edge as compare to D2 steel.
