Description
420MoV / 1.4116 / X50CrMoV15
X50CrMoV15 /1.4116 /420MoV is a high hardness martensitic stainless steel. In strip form, its dominant use is for high quality knife blades.
Approximate Composition – 15% Cr, 0.7% Mo, 0.15% V, 0.50% C
This grade combines the following characteristics:
-
Very high hardness – Up to 56 Rockwell C
-
Retention of blade sharpness
-
Moderate corrosion resistance better than standard 12% martensitic grades
-
Poor weldability
X50CrMoV15 uses the moderately high carbon content of 0.50% to develop a high hardness martensitic microstructure. The higher chromium plus small molybdenum addition gives a greater corrosion resistance than standard martensitic grades. Vanadium allows higher tempering temperatures to be used and gives greater toughness.
