High quality, value-added products
NSSC produces a range of truly unique products that will continue to drive its growing presence in the global market. NSSC FWTM (Forward) series and duplex NSSC 2120TM are typical examples. Mr. Ito explains: “The FW series is the world’s first stainless steel with added tin, which is nickel-free and contain less chromium than other grades. As such, they are not only cost-saving products but also have considerable price stability against the fluctuation of material price. They allow us to keep our competitiveness in the generic product market where it is quite challenging to make a profit.”
“Original duplex stainless steel NSSC 2120 is a high-strength and good corrosion resistance material as well as superior weldability. In the past, the disadvantage of duplex was its poor weldability, so we improved quality of welded area on developing NSSC 2120. It has proven its value in various and actual applications such as floodgates and land-locks required for seismic protection, and to improve the resilience of national lands against natural disasters such as flooding and tsunamis. The material is increasingly specified for applications in public infrastructure. For example, the Tokyo metropolitan government undertook a project to install bridges constructed of this duplex to connect esplanades along the Sumida River. Sales of these strategic products continues to expand by meeting a wide variety of customers’ needs and requests,” explains Mr. Ito.
New duplex celebrates integration: NSSC 2351TM
In September 2019, the company rolled out its first post-integration product: Integration Commemorative Product NSSC 2351. Based on an upgrade of the NSSC 2120 grade, as the result of integration, in-house knowledge was shared and multiplied, resulting in the successful development of a superior product with even greater corrosion resistance.
Mr. Ito commented: “With this development, the next generation series of duplex stainless steel offers even more choices - covering our generic austenite stainless steels from type 304 to 316! For the 2351 grade, we are targeting at infrastructure facilities in brackish water environments that utilise corrosion protection; as well as tanks and containers in the food and pharmaceutical industries.”
“It’s a perfect example that the integration was not just a simple addition of the technical capabilities, but an opportunity for us to get appended synergy through our own and joint efforts made by all the team especially on the field of new products development.” The demands for duplex for civil engineering projects are increasing, and there has been correspondingly high demand for NSSC’s original new duplex steel grade.
“In an environment where lifecycle cost translates to a demand for prolonged maintenance life, stainless materials are one of the best optimal choices. Our original duplex steel not only offers stainless steel’s superior performance such as corrosion resistance in this regard, but the weight of the product can be reduced by 25% due to its high strength. We see high ratings and increased demand for these products.”
