8cr13mov and AUS-8 are both mid-range stainless steels used in knife making. Although similar, they have distinct differences in composition and performance.
8cr13mov generally achieves higher hardness levels (58-62 HRC) compared to AUS-8, which usually ranges from 57-59 HRC. This higher hardness results in better edge retention for 8cr13mov, making it suitable for users who need a longer-lasting edge. Both steels offer good corrosion resistance due to their chromium content. However, AUS-8’s slightly higher chromium content can provide marginally better resistance to rust and staining, particularly in more corrosive environments.
VG-10 is a high-end stainless steel that offers superior performance compared to 8cr13mov.
VG-10 typically achieves a Rockwell hardness of 60-62 HRC, which is comparable to the upper range of 8cr13mov. However, VG-10’s higher carbon and additional alloying elements give it superior edge retention and overall cutting performance.
VG-10’s higher chromium content and additional alloying elements provide excellent corrosion resistance, making it a preferred choice for premium knives exposed to harsh environments.
In conclusion, 8cr13mov stainless steel offers a balanced combination of properties suitable for various knife applications. While it may not match the performance of higher-end steels like VG-10 or D2, its affordability and overall quality make it a popular choice for both casual users and professionals.
Proper cleaning and drying after each use help maintain the quality of 8Cr13MoV stainless steel. Use a soft cloth and mild soap to remove any residues. Rinse the blade with warm water and dry it immediately to prevent moisture from causing rust or corrosion. Avoid using abrasive cleaners or harsh chemicals, as they can damage the steel surface.
After cleaning, apply a thin layer of oil to prevent rust and keep the blade sharp. Use gun or machine oil and apply it evenly across the blade. Regular oiling is necessary to keep the steel in good condition and prevent corrosion.
For sharpening 8Cr13MoV stainless steel knives, use a high-quality knife sharpening stone or a work sharpener. Start with coarse grit to shape the edge, then use finer grits for sharper results.
Sharpen the blade at a 15-degree angle for optimal results. This angle provides a balance between sharpness and edge durability, making it suitable for various applications.
Regular honing helps maintain the blade’s sharpness without removing material. Use a steel honing rod, holding it at a 90-degree angle to the blade edge. Run the blade along the rod from the handle to the tip to straighten any micro-serrations and keep the edge in top condition.
Store knives in a dry, ventilated area to prevent rust. Use a knife block, magnetic strip, or protective sheath to store the knives. This prevents the blades from touching other utensils, which can dull the edge and cause scratches.
Use a toothbrush and baking soda to gently scrub light rust without harming the steel. For more severe rust, use metal polishes like Flitz or Bar Keepers Friend. Follow the product instructions to effectively remove rust and restore the blade’s appearance.
Regularly inspect 8Cr13MoV steel products for signs of corrosion or wear. Address any issues promptly to prevent significant damage. Regular maintenance ensures the longevity and performance of the steel.
