Stainless Steel Tubing ASTM A312 TP321H Steel Tube With High Strength
ASTM A312 TP321H seamless pipe is non-magnetic in the annealed condition and can be hardened only by cold working. Titanium is added to the alloy’s composition to suppress grain boundary chromium carbide precipitation and reduce susceptibility to inter granular corrosion. Also referred as WNR 1.4878 seamless pipes, we also offer those alloy 321H seamless pipes at customized sizes and shapes according to your requirements.
