二. Application
7Cr13Mo
Application areas: 7Cr13Mo is a high-hardness, high-wear-resistant martensitic stainless steel with good corrosion resistance and wear resistance.
Common applications: Mostly used in the manufacture of medical devices (such as scalpels, scissors), high-end tableware, razor blades, and knives that require high hardness and corrosion resistance.
X65CrMo14
Applications: X65CrMo14 is a chromium-molybdenum stainless steel with high strength, good corrosion resistance and wear resistance, and is often used in situations where high durability is required.
Common applications: Widely used in knives, scissors, medical equipment, food processing equipment, and other precision parts that require high hardness and high toughness.
8Cr14MoV
Application areas: 8Cr14MoV stainless steel is often used to manufacture mid-to-high-end knives due to its good wear resistance, corrosion resistance and processing performance.
Common applications: Mainly used for kitchen knives, outdoor knives, daily utility knives, etc. These knives need to have both sharpness and durability.
9Cr18MoV
Application areas: 9Cr18MoV is a high-chromium, high-carbon martensitic stainless steel with extremely high hardness and good corrosion resistance after quenching.
Common applications: Widely used in high-end razor blades, precision bearings, medical devices (such as scalpels), high-end knives, and some mechanical parts with high corrosion resistance requirements.
