About 321H grades-
Stainless steel 321H is the austenitic general purpose stainless steel alloy that is developed against carbide precipitation and to work in carbide precipitation temperature ranging 800 to 1500 Deg F. This alloy is also known as UN S32109 and is non-magnetic in nature in the annealed condition and it can be hardened through the process of cold working. Also, titanium alloy is added in these SS 321H pipes to the composition of alloy for suppressing the grain boundary chromium carbide precipitation and reduces susceptibility to the intergranular corrosion.
