Overview
304 Stainless Steel
1.4301
The most widely used austenitic stainless steel. Excellent corrosion resistance, good formability and weldability. Standard choice for food processing, chemical, and architectural applications.
X2CrNiMoN22-5-3
1.4462
The most widely used duplex stainless steel worldwide (SAF 2205 / UNS S31803/S32205). Austenitic-ferritic microstructure provides ~2× yield strength of 304/316 (≥450 MPa) with excellent resistance to stress corrosion cracking, pitting (PREN 33-38), and intergranular corrosion. Service temperature -50°C to 300°C. Used for oil & gas production tubing, chemical processing vessels, desalination plants, pulp & paper digesters, heat exchangers, and bridge structures. Weldable with ER2209 filler.
