2205 stainless steel strip is a duplex stainless steel strip 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.
The yield strength of duplex 2205 stainless steel strip is more than twice that of normal austenitic stainless steel strip.
This feature enables engineers and designers to reduce weight when designing related products, making this strip more cost-effective than 316L stainless steel strip and 317L stainless steel strip.
This strip is especially suitable for the temperature range of from -50°F to +600°F.
