Stainless Steel 441 Sheets Strips Coil
This grade contains more than 17.5% chromium endowing it with good corrosion resistance. It is dual stabilized with niobium and titanium, thus ensuring excellent resistance to inter-granular corrosion. The addition of niobium improves high temperature oxidation resistance, creep and thermal fatigue resistance. In addition, it leads to a fine equiaxed grain structure with excellent deep drawability. On account of very low interstitial content and stabilization, this steel is characterized by good weldability and retains good mechanical properties in heat affected zone of weld. 441 is a good choice for the manufacture of automotive exhaust systems that require good mechanical strength at high temperature, corrosion resistance at high and low temperature and good cold ductility
