D2 stainless resistant steel aloy bar for knife blade making
It is annealed with a clean surface.
12% Chromium (Cr). The main driver for corrosion resistance. The corrosion resistance achieved is related to the amount of Cr dissolved into the steel matrix and not related to the nominal composition.
1,50% Carbon (C).The main driver for hardness. The hardness is related to the amount of carbon dissolved in the steel matrix. By tying up chromium into carbides the carbon is indirectly decreasing corrosion resistance.
0,90% Vanadium (V). A strong carbide former. The vanadium carbides are also very stable and do not dissolve during heat treatment.
1% Cobalt (Co). Increases strength and hardness, and permits quenching in higher temperatures. Intensifies the individual effects of other elements in more complex steels.
0,80% Molybdenum (Mo). Drives carbide formation and has a small influence on hardness and corrosion resistance in martensitic stainless grades.
0,60% Silicon (Si). Increases strength. Deoxidizes and degasifies to remove oxygen from molten metal.
0,60% Manganese (Mn). Increases hardenability, wear resistance, and tensile strength. Deoxidizes and degasifies to remove oxygen from molten metal. In larger quantities, increases hardness and brittleness.
0,30% Nickel (Ni). Adds strength and toughness.
0,30% Phosphorus (P). Improves strength, machinability, and hardness. Creates brittleness in high concentrations.
0,25% Copper (Cu). Increases corrosion resistance.
0,03% Sulphur (S). Forms sulphide inclusions which have a negative influence on the initiation of pitting corrosion.
