J & J Alloys is an industry leading manufacturer of nickel alloy fitting and flanges with a wide array of standard as well as specialty products we are capable of producing.
These titanium-bearing stainless steels are stabilized against carbide precipitation. They are designed for operation within the damaging temperature range where carbide precipitation develops. In this type of steel, the carbon combines preferentially with titanium to form a harmless titanium carbide, leaving the chromium in solution to maintain full corrosion resistance. Type 321 is basic type 304 modified by adding titanium in an amount at least 5 times the carbon-plus-nitrogen contents.
