321h Stainless Steel Sheet



What is 321h Stainless Steel Sheet?

Stainless 321h is an austenitic compound that is stabilized by titanium. Stainless Steel 321H Plate is a high carbon modification of the 321 grade. Designed with a superior chemical concentration constituting of nickel and chromium, the SS 321h Plate performs well in corrosive and oxidative media. These plates are designed to withstand temperatures ranging up to 1500 degrees F. The 321h Stainless Steel Sheet shows excellent tolerances against creep-rupture while being readily resistant against intergranular corrosion. The non-magnetic SS 321h Sheet is stabilized against carbide precipitation.

SUS 321H Foil Density

321h is an austenitic high carbon grade stabilized by titanium. The density of the austenitic 321h stainless is 8027 kg/m3.

Density Melting Point
8.0 g/cm3 1457 °C (2650 °F)


Welding Process of SS 321h Sheet

321h Stainless is a high carbon steel component that is stabilized by titanium, making it difficult to weld. The titanium in these modules doesn’t transfer well with a high-temperature arc, making it welding consumable. Once welded, these components don’t require post-weld annealing or treatment.
