Nascent Pipe & Tubes is a well-known firm that manufactures and stockist a wide range of SS 321 / 321H Bolts / Nuts, which is a heat resistant grade and supplied into numerous industry sectors. Low carbon grades like Stainless Steel 321 Bolts have insufficient carbon to deplete the chromium content generally throughout the structure.
Stainless Steel 321H Bolts has similar corrosion behavior to Stainless Steel 304 with the exception of improved inter-granular corrosion resistance due to the titanium addition for stabilization. Stainless Steel 321 Nuts is primarily used in applications that involve continuous and intermittent service temperatures within the carbide precipitation range of 800°-1500°F. Solution Treatment (Annealing) – heat this Stainless Steel 321H Bolts up to 950-1120 °C and cool rapidly for maximum corrosion resistance.
