High hardness and high corrosion resistance, biocompatibility evaluation obtained, medical device grade new stainless steel 'ASK-3900'.
"ASK-3900" is a martensitic stainless steel that combines hardness comparable to SUS440C and corrosion resistance equivalent to SUS630. Biological safety tests conducted (GLP standards) Negative confirmation obtained through cell characteristics/skin sensitization/intradermal reaction tests. *Suitable characteristics for surface contact equipment such as steel small parts. 【Features】 ■ By suppressing primary carbides, it achieves better machinability than SUS440C. ■ By adding Cr, Mo, and N, it achieves corrosion resistance exceeding SUS420J2 and SUS440C, comparable to SUS630 and 303. ■ Achieves approximately 1.6 times the cold workability of SUS440C. ■ By adding C and N, it achieves hardness comparable to SUS440C, exceeding SUS420J2. *For more details, please refer to the PDF document or feel free to contact us.
