420

420 steel is considered the lowest range among knife steels, used especially in low end knives. Blades made of this steel have good corrosion resistance. Edge holding ability is very low, meaning the knives need to be sharpened quite often. 420 stainless steel has low carbon content (<0.38%).

Steel composition: 0,15 - 0,38% Carbon, 13% Chromium, 1% Manganese, 1% Silicon, 0,6% Nickel, 0,09% Copper, 0,04% Phosphorus, 0,03% Sulfur
