If you are looking for high-strength, wear-resistant stainless steel sheet for knives, we offer 420J2 Stainless Steel Metal Sheet for Knives, designed specifically for high-performance knife manufacturing. 420J2 stainless steel is a high-carbon martensitic stainless steel with 12-14% chromium (Cr) and a high carbon (C) content, giving it excellent corrosion resistance while providing extremely high hardness and wear resistance. It is suitable for making kitchen knives, industrial cutting tools, and other high-load knives.
420J2 stainless steel sheets are precision cold-rolled and available in thicknesses from 0.5mm to 10mm. Custom sizes are available upon request.
Our 420J2 stainless steel knife sheet, after hardening treatment, achieves a high hardness of 57-60 HRC, ensuring excellent cutting performance and a long knife life. Its oxidation and corrosion resistance make the knives perform exceptionally well in humid environments, suitable for various industries such as food processing, outdoor equipment, and craft knives. Products meet international standards and are available with ISO and SGS quality certifications, ensuring consistent quality across every batch.

What are the differences between Stainless Steel 420 / 420J1 / 420J2?
Stainless Steel 420, 420J1, and 420J2 are all martensitic stainless steels known for hardness and corrosion resistance, but they differ mainly in carbon content, with 420J2 having the most carbon, making it the hardest and strongest after heat treatment, while 420J1 has the least, offering better corrosion resistance and workability, with standard 420 falling in between for a balanced profile.
