May I ask: What domestic material is equivalent to the Japanese standard YUS170?
Reply #22017-08-15
The product YUS170 from Nippon Steel & Sumitomo Metal in Japan is an old specification number; it has now been changed to \"NSSC170\". It belongs to the austenitic series (abbreviated as A), with a composition of (25Cr-13Ni-0.9Mo-0.3N). This steel grade is not available in China. The relevant information pertains to the super duplex stainless steel type – standard grade: UNS S32750 (25Cr-7Ni-3.7Mo-0.3N).
