what is 321 Stainless Steel Plate?
321 stainless steel plate is a type of stainless steel plate that
is made from an austenitic alloy containing chromium, nickel and
titanium. It is non-magnetic and has excellent corrosion
resistance, making it ideal for applications in corrosive
environments. It is often used in the fabrication of exhaust
systems, turbochargers, and other high-temperature components.
what's the character of 321 Stainless Steel Plate?
321 stainless steel plate is a stabilized austenitic stainless
steel with good general corrosion resistance. It has excellent
resistance to intergranular corrosion after welding and exposure to
elevated temperatures. It has good creep strength and stress
rupture properties. It also has excellent low temperature toughness
and ductility.
321 stainless steel plate offers a variety of benefits, including:
resistance to corrosion and oxidation, superior strength at high
temperatures, excellent formability and weldability, and a low cost
of ownership due to its long lifespan. Additionally, 321 stainless
steel plate is non-magnetic, making it ideal for use in
applications where a non-magnetic material is required.

Application of 321 Stainless Steel Plate
These stainless steel plate grades have a wide range of
applications, particularly in settings where higher temperatures
are necessary. These stainless steel plate grades are frequently
employed in heat exchangers, bellows, expansion joints, heating
element tubing, spiral-welded tubes for burner pipes and flues, as
well as furnace components. For use in high-temperature mineral
processing, this type of stainless steel plate is also used in
woven or welded metal screens. It is used in the aerospace sector
as well, notably in piston engine manifolds and aircraft exhaust
systems. These grades are helpful for equipment and storage in the
chemical and food processing sectors. These grades are also well
suited for use in waste treatment procedures, the chemical sector,
and petroleum refining.
