Уникальные особенности:

420 stainless steel sheet is unique for its high carbon content and ability to be hardened through heat treatment, which gives it excellent wear resistance and hardness. This material is often used for applications that require both strength and edge retention. When heat-treated, 420 stainless steel can reach hardness levels up to 50-55 HRC (Rockwell hardness scale). The alloy’s moderate corrosion resistance makes it suitable for environments where corrosion is not a primary concern but where mechanical strength and resistance to wear are essential. This grade is often chosen for manufacturing parts like knives, scissors, and other tools that need to maintain a sharp edge over time.
