1.4460 (EN 10088-3) Duplex Stainless Steel Round Bar OD 50mm With Certificate Type 3.1 EN10204.

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.
