| High Light | 2207 Stainless Steel Hot Rolled Plate ，Stainless Steel Hot Rolled Plate Duplex | ||
Duplex 2205 stainless steel plate is a nitrogen-enhanced duplex stainless steel grade characterized by a balanced austenitic-ferritic microstructure (approximately 50% austenite / 50% ferrite). This unique dual-phase structure delivers approximately twice the yield strength of standard austenitic grades like 304L or 316L, combined with excellent resistance to chloride stress corrosion cracking (SCC), pitting, and crevice corrosion.
Duplex 2205 is the most widely used duplex stainless steel grade, serving as the standard choice for applications requiring both high strength and superior corrosion resistance in chloride-containing environments.

| Seawater Resistance | Excellent; widely used in seawater systems with proper design |
Temperature range: 1750 – 2050°F (950 – 1120°C), followed by rapid cooling (water quenching). Avoid working below 1700°F (925°C).
Requires approximately 30-50% higher forming force compared to 316L. Intermediate annealing may be required for severe deformation.
Solution Annealing: 1870 – 2010°F (1020 – 1100°C)
Cooling: Water quench or rapid air cool
Hardening: Not hardenable by heat treatment; only through cold working
Suitable with standard methods (SMAW, GTAW, GMAW, SAW, FCAW)
Recommended filler metal: 2209 (E2209 or ER2209)
Control heat input (0.5 – 2.5 kJ/mm) to maintain phase balance
Preheat is generally not required
Post-weld heat treatment is not typically needed
Avoid overheating to prevent intermetallic phase precipitation
Requires rigid tooling and lower cutting speeds due to higher strength and work hardening tendency compared to austenitic grades.
