2205 alloy duplex stainless steel plate is composed of austenite-ferrite duplex structure, and is a duplex stainless steel composed of 22% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. It has high strength, good impact toughness and good overall and local stress corrosion resistance. And follow the standard ASTM A240.
Key Advantages
2205 Duplex Stainless Steel Plate In addition to high strength and corrosion resistance, 2205 alloy also has good overall and local stress corrosion resistance, and its yield strength is more than double that of ordinary austenitic stainless steel.
Duplex 2205 Stainless Steel Plate field:
2205 super stainless steel plate is widely used in fields such as oil, gas, marine engineering, chemical industry, pharmaceutical and biotechnology industries, especially in the temperature range of -50°F/+600°F.
