Overview
329 grade stainless steel plate is a duplex stainless steel that combines the benefits of both austenitic and ferritic structures. It offers excellent corrosion resistance, high strength, and superior resistance to stress corrosion cracking, making it ideal for demanding environments such as the chemical, petrochemical, marine, and food processing industries.

Performance Features
-
Excellent resistance to pitting and crevice corrosion, especially in chloride-containing environments.
-
High tensile and yield strength, roughly twice that of common austenitic stainless steels like 304 and 316.
-
Superior resistance to intergranular corrosion and stress corrosion cracking.
-
Good weldability and formability with proper procedures.
-
Stable performance in both oxidizing and reducing conditions.
Applications
329 stainless steel plate is widely used in environments that require both strength and corrosion resistance:
-
Chemical processing equipment – heat exchangers, pressure vessels, piping systems
-
Food and beverage industry – tanks, mixing vessels, conveyors
-
Marine and offshore applications – seawater cooling systems, pumps, valves
-
Pulp and paper industry – bleach washers, digesters
-
Oil and gas industry – refinery components, separators, pipelines
