Next generation duplex stainless steel

NIPPON STEEL Stainless Steel Corporation has developed as a commemorative product of the merger the unique duplex stainless steel “NSSTS2351â€? (23Cr-5Ni-1Mo-N) which is the upper grade for SUS316/316L (hereinafter the “SUS316 seriesâ€?) and able to replace the SUS316 series. NSSTS2351 can be used under severe corrosive environments including brackish water, and its higher strength can reduce steel volume that may lead to cost down. It is a brand-new product which can offer a new value to customers together with improved weldability.

The lineup of the next generation duplex stainless steel, including NSSTS2351 and NSSTS2120 (former NSSC 2120® announced in 2012 and currently obtaining high reputation) can be replaceable with generic austenite stainless steel SUS304 and SUS316 with better weldability.

NSSTS2351 features (i) higher corrosion resistance (ii) excellent weldability (iii) higher strength and (iv) cost performance and resource saving.

In terms of potential applications, NSSTS2351 covers the applications not only for foods, chemical tanks, etc. which the SUS316 series are used, but also for high corrosion resistance in infrastructure equipment such as the water gates in waterfront areas. It has excellent capability with reasonable cost. Also, NSSTS2351 is the steel equivalent to SUS329J1 and conformable for the boiler and pressure vessel code. We manufacture NSSTS2351 for both of sheets and plates for various applications for customers.

NIPPON STEEL Stainless Steel Corporation indicate its determination to contribute to society by providing a new value in a wide range of demands through the solution of the next generation duplex stainless steel.
