Material
Stainless Steel 2205 (Duplex)
Duplex Stainless Steel 2205 combines roughly double the yield strength of standard austenitic grades with excellent resistance to chloride pitting, crevice corrosion, and stress corrosion cracking.
Manufacturing processes
About
2205 is a duplex (mixed austenite-ferrite) stainless steel with high chromium, molybdenum, and nitrogen content, giving it a Pitting Resistance Equivalent Number (PREN) around 33-35 – well above 316L – and yield strength roughly twice that of standard austenitic grades. This allows thinner, lighter parts under the same load.
Stainless Steel 2025 isn't recommended for continuous use above ~300 °C, where toughness drops sharply, and it needs higher forming forces than austenitic grades. It is more suitable for marine hardware, chemical processing components, and oil & gas fittings exposed to chlorides.
