Description

<p>To improve price stability, stainless steel manufacturers have focused on developing new stainless steel reduced Ni and Mo content, known as rare metal. SUS821L1 and SUS323L, lean duplex stainless steels, were registered in the list of the JIS （Japanese Industrial Standards） in 2015. Corrosion resistance of SUS821L1 and SUS323L are almost equal to that of SUS304 and SUS316L respectively. SUS304 and SUS316L are known as major austenitic stainless steels. In addition, these lean duplex steels have strength equal to that of SUS329J3L or SUS329J4L, known as traditional duplex stainless steels. In this report, characteristic properties of these lean duplex stainless steels with that of SUS304 or SUS316L are described, and some suitable application examples are introduced.</p>
