The Stainless Steel Type 329 is duplex steel being a combination of austenitic and ferritic types. It can resist pitting as well as corrosion cracking under stress. This type of steel is better to use in forged valve pumps and their components.
Type 329 is also frequently used for centrifugal machines. This type of steel forges better at temperatures around 1250/1050C or 2280/1900F. The parts need to be air-cooled once they are forged. Duplex steel of such grade is very difficult to weld, and hence its machinability is very low.
Common Names: The other names of stainless steel 329 are AISI 329, and UNS S32900.

329 Stainless Steel Application
UNS S32900 is a primary metal alloy used in many applications across industries. Its ability to retain strength and resist corrosion makes it an ideal material for a variety of projects, from construction to food processing. In construction, its extraordinary tensile strength makes it a great choice for bolts and other structures that require stability when experiencing movement and vibration. Additionally, its excellent corrosion resistance has made it popular for chemical processing applications such as pipes, valves and pumps that have frequent contact with liquids or vapours. Lastly, 329 stainless steel is great for food processing as it can handle prolonged contact with liquids like acid-based foods or alcoholic beverages without suffering wear and tear or discolouration over time. Clearly, 329 stainless steel is one of the most useful metals available today due to its wide range of applications.
