1. What is SA240 Type 329 (S32900)?

SA240 Type 329, also known as UNS S32900, is a duplex stainless steel alloy with a balanced microstructure of approximately 50% austenite and 50% ferrite. It features high chromium (23.0-28.0%), nickel (2.5-5.0%), and molybdenum (1.0-2.0%), delivering high strength, good corrosion resistance, and resistance to stress-corrosion cracking (SCC) in chloride-heavy environments like seawater.

SA240 Type 329 materialis ideal for applications requiring durability and corrosion resistance, such as chemical tanks, marine equipment, and oilfield components. Compared to SA240 Type 2205, SA240 Type 329 offers similar strength but slightly lower pitting resistance (PREN ~30), making it a cost-effective choice for less aggressive environments.

Gangsteel’s SA240 Type 329 stainless steel plate is engineered for industries needing reliable performance, offering a versatile alternative to grades like SA240 Type 2507 or SA240 Gr 316.
