 Knives |  |  EN Name Used for Marketing |
X50CrMoV15 is a high hardness martensitic stainless steel. In strip form, its dominant use is for high quality knife blades. This is a rare, possibly a unique, example of the EN Name of a stainless steel grade being used for marketing purposes. Approximate Composition – 15% Cr, 0.7% Mo, 0.15% V, 0.50% C (EN composition range. No ASTM equivalent). 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. Applications which illustrate these features include: High quality knives, cutting tools. |
