1. What is SA240 Type 2304 (S32304)?

SA240 Type 2304, also known as UNS S32304, is a lean duplex stainless steel alloy with a balanced microstructure of approximately 50% austenite and 50% ferrite, featuring chromium (21.5-24.5%), nickel (3.0-5.5%), and low molybdenum (0.05-0.60%). This composition provides high strength, good corrosion resistance, and excellent resistance to stress-corrosion cracking (SCC), particularly in chloride-containing environments. SA240 Type 2304 material is ideal for applications requiring a cost-effective alternative to austenitic grades, such as storage tanks, structural components, and marine equipment.

Compared to SA240 Type 2205, SA240 Type 2304 has lower molybdenum and nitrogen, offering slightly less corrosion resistance but at a more economical price point, with a pitting resistance equivalent number (PREN ~25).

Gangsteel’s SA240 Type 2304 stainless steel plate is engineered for industries seeking durability and affordability, providing a cost-effective alternative to grades like SA240 Gr 316 or SA240 Type 2507.
