| Category | Details |
|---|---|
| Characteristics | Austenitic stainless steel (304/304L, 316/316L); seamless construction; 316/316L includes 2-3% molybdenum for enhanced corrosion resistance. |
| Surface Treatment | Mill finish, polished (180/240/320 grit), or electropolished (down to 10 ¦Ì¡± Ra for high-purity uses). |
| Dimensions and Specifications | Sizes: 1/2" x 1/2" to 12" x 12"; Wall thickness: 0.035" to 1.000"; Length: Up to 30 ft or custom. |
| Corrosion Resistance | 304/304L: Good in mild environments; 316/316L: Superior in chloride-rich settings (marine, chemical). May pit in warm seawater over time. |
| Mechanical Properties | 304/304L: Yield ~215 MPa, Tensile ~505 MPa, Elongation ~40%, Hardness ~88 HRB. 316/316L: Yield ~205 MPa, Tensile ~515 MPa, Elongation ~40%, Hardness ~95 HRB. |
| Processability | Good formability (bending, drawing); weldable (TIG/MIG; 304L/316L preferred); machinable. Anneal at 1010-1120¡ãC (304) or 1038¡ãC (316) to restore properties. |
| Applications | Aerospace (hydraulics), oil/gas (CO2 injection), chemical processing (heat exchangers), pharmaceutical/food (sanitary systems), marine structures. |
| Standards | ASTM A213, A269, A511; AMS 5564, 5565 (aerospace); UNS S30400/S30403 (304/304L), S31600/S31603 (316/316L). |
