优点

Superior Wear Resistance: The high carbon content creates hard carbides that provide excellent edge retention compared to standard stainless steels.
High Hardness Capability: It can be hardened up to 60-63 HRC, allowing for a very fine and sharp edge suitable for precision cutting.
Great Compressive Strength: The steel offers excellent stability and resistance against deformation during heavy-duty cutting tasks.
Proven Industrial Performance: Long-term reliability in both industrial applications and professional kitchen environments.

缺点

Lower Toughness: Due to the relatively large carbides, the steel can be brittle at high hardness and may chip if subjected to heavy impact or prying.
Moderate Corrosion Resistance: With 13.5% Chromium, it sits at the lower end of the stainless spectrum and requires proper cleaning to prevent spotting or rust.
Difficult to Sharpen: Its high wear resistance makes it significantly harder to regrind or sharpen using manual stones compared to softer grades like 12C27.
Sensitive Heat Treatment: Achieving optimal performance requires precise temperature control and professional quenching processes.
