In the field of medical device manufacturing, materials must possess high hardness, corrosion resistance, sterilizability and stable mechanical properties. 420 stainless steel, due to its excellent hardness and wear resistance, is widely used in surgical blades, scissors, dental tools, micro-cutting instruments and other medical tools. Its high-carbon martensite structure can significantly increase hardness through quenching, making its cutting sharpness and wear resistance longer than many other stainless steel materials.
Compared with austenitic stainless steels such as 304 and 316, although 420 stainless steel has slightly lower corrosion resistance, its higher hardness, excellent polishing performance and sterilization property make it the preferred material in the field of medical cutting tools. Moreover, 420 stainless steel can withstand high-temperature and high-pressure sterilization environments without deforming, ensuring the accuracy and safety of medical operations.
In terms of standards, the medical-grade 420 stainless steel must comply with international standards such as ASTM and ISO, ensuring that the material meets the requirements for medical use in terms of composition, mechanical properties, and corrosion resistance. After processing, it also needs to undergo strict polishing, passivation, and surface testing to ensure the safety and stability of the medical devices.
