NSSC180 in a general environment (in the salinization of the environment), and the corrosive SUS304 face the same high-grade ferrite stainless steel.
NSSC180 to JIS steel (SUS430J1L), by increasing the chromium content, add small amount of nickel and other elements, improve corrosion resistance of the unique species.
NSSC180 element of the design did not use the rising price of molybdenum, not only taking into account its corrosion resistance, but also take into account the processing performance and welding performance.
NSSC180 in a variety of purposes, has been in use for 25 years, the actual annual production of 20,000 tons!
