D grade control the content of the nickel, which improves the content of manganese, and D grade is an austenitic stainless steel which consists of Cr-Mn-Ni-Cu also adds copper.
D grade is non-magnetic and high strength, it is possible to reduce the cost comparing with SUS304. D grade has a similar corrosion resistance with SUS304. D grade is used for pans such as properties, connectors, cellular phone, electrical parts, and automobile parts and etc.
Beyond the grade of SUS304 represents a stainless steel, NTK provides the many variety of stainless steel grades in order to meet the customer satisfactions and requirements such as press working, weld ability, corrosion resistance and etc.
Process production and the research and development were consolidated in Aichi Prefecture, Hekinan City where offers the cold-rolled steel sheet and the hot-rolled sheet steel with the high productive efficiency and the high quality.
NTK’s Ultra thin steel strip demonstrates the great ability of the process productions, individual usage, development, the selection, the thickness accuracy and the flatness are offering extremely excellent products.
The hardware material and the BA finish of stainless steels are for the spring that can be used for electric appliance parts, automobile parts, button batteries, printers, gaskets and brakes.
