D series grade is Cr-Mn-Ni-Cu austenitic stainless steel saving Ni content and adding Mn and Cu.
D series grade allow to save products cost compared with SUS304 and have wide variety of applications such a pot and pan, the electric parts like connectors and mobile phone and parts for automobiles with its properties of high strength, non-magnetic and corrosion resistance close to SUS304.
Since we succeeded first manufacturing "Stainless steel in 1932, the history of stainless steel had started. We always endeavor to develop new technologies, streamline equipments and develop new applications over time.
Stainless steel have significantly been developing as a most familiarized steel in our daily life with wide range of applications to the kitchen equipment, construction, electronics and heavy chemical industry due to its excellent corrosion resistant and high performance. Nippon Metal Industry targets to contribute creating comfortably affluent life and communities through "Stainless steel". We strive to research and develop the technologies in order to satisfy demands which will get more and more diversified and advanced, and we keep up with the wide variety of demands as a stainless steel specialized manufacturer.
