Sandvik 12C27 stainless steel flat bar for knife making
It is annealed with a clean surface.
Sandvik 12C27 is a martensitic stainless chromium steel with an optimized analysis for high quality professional knife applications. After heat treatment, the composition of carbon and chromium gives a unique combination of properties including:Very high hardness, good corrosion resistance, very high wear resistance. Typical applications for Sandvik 12C27 are hunting and fishing knives, pocket knives, skate blades and ice drills.
13,5% Chromium (Cr). Added for increased wear resistance, hardness, tensile strength, and (most importantly) for corrosion resistance. Cr forms large, complex carbides. A steel with at least 13% chromium is typically deemed "stainless".
0,60% Carbon (C). Present in all knife steels, it is the most important hardening element. Increases tensile strength and edge retention and improves resistance to wear and abrasion. Added in isolation, decreases toughness.
0,40% Manganese (Mn). An important element, Manganese improves grain structure and contributes to hardenability, strength, and wear resistance. Improves the steel, deoxidizes and degasifies during the steel's manufacturing (hot working and rolling).
0,01% Silicon (Si). Contributes to strength. Like Manganese, deoxidizes and degasifies to remove Oxygen from molten metal.
