METCORE Alloys is among the well-identified manufacturers, suppliers, exporters, and stockists of Stainless Steel 321H Pipes.The titanium addition in Stainless Steel 321H Pipes provides them with resistance against carbide precipitation, which is called sensitization, after exposures in the temperature range from 800°F to 1500°F. This particular ability differentiates it from other stainless steel grades. With a higher carbon content of 0.04 to 0.10%, these Stainless Steel 321H Pipes are much stronger and possess better creep resistance; as such, they are suitable for high-temperature applications.
Stainless Steel 321H Pipes are available as welded and seamless. The SS 321H Seamless Pipe is manufactured from one piece of steel with no seams or joints, and the tensile strength is above 515 MPa, while the yield strength must be above 205 MPa. On the other hand, SS 321H Welded Pipe is manufactured through welding and cannot be defective due to various factors like post-weld carburization or even corrosion.
These pipes, along with other products, can be provided in different shapes and sizes according to the demand of specific industries. The DIN 1.4878 Stainless Steel Round Pipe is produced to generally adopted standard. It finds its application mainly in transporting fluids and gases. The SA 312 TP 321H Square Pipe is used in structural applications and is hot-rolled but cannot be hardened, whereas ASTM A312 Gr. TP 321H Rectangular Pipe has widespread application in aerospace and storage because of the higher strength and hardness.
Metcore Alloys are reputed manufacturers, suppliers, exporters, and stockists of these high-grade stainless steel pipes, assuring the best quality solutions to our clients all over the world. For further detail or inquiry of our ASTM A312 TP321H Pipes please do not hesitate to contact us directly.
