Product DescriptionProduct Description17-4PH stainless steel typically undergoes solution treatment (1020-1060°C) followed by age hardening (H900: 480°C/1h or H1025: 550°C/4h), achieving a hardness of HRC 40-45 after processing. For 420J2 stainless steel, quenching (980-1030°C oil cooling) and low-temperature tempering (150-400°C) are required, with a hardness range of HRC 50-55. Medical drill bits must combine high hardness with appropriate toughness, necessitating strict optimization of heat treatment parameters. Their surfaces are generally coated with hard chromium plating (approximately 2-5μm thick) to enhance wear resistance and resistance to bodily fluid corrosion. After plating, dehydrogenation treatment (180-200°C/3h) is required, ensuring the coating is pore-free and strongly bonded, complying with medical device biocompatibility standards such as ISO 13485.Main ProductCompany ProfileDongguan Yu Lin Sen Metal Technology Co., Ltd.: Has obtained theGB/T 19001-2016/ISO 9001:2015 quality system certification, as well as the GB/T42061-2022/ISO 13485:2016 medical device quality system certification.
