ASTM A312 TP321H Pipe

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.

These pipes are possessing excellent low-temperature toughness. The pipes offered are varying differently in wall thickness, standards, outer diameter, types, forms, length, ends, etc. All across the globe these pipes are appreciated greatly for excellent attributes possessed by it and are used in many applications like oil and gas, fertilizers plants, water treatment, etc.
