一， Overview of 2205 duplex stainless steel:
2205 duplex stainless steel is austenitic-ferritic duplex stainless steel (abbreviated as 2205 duplex steel) consisting of 22% chromium, 3% molybdenum and 4.5% nickel-nitrogen alloy. 2205 duplex stainless steel is a nitrogen-added duplex stainless steel with high strength, good impact toughness and good overall and local resistance to stress corrosion. 2205 duplex steel is especially suitable for use in the temperature range of -50°F/+600°F. Alloys are also considered for applications outside this temperature range.
The main feature of 2205 duplex stainless steel is that the yield strength can reach 400-550MPa, which is twice that of ordinary austenitic stainless steel. This feature allows the designer to reduce the weight when designing the product, so the material can be saved. This alloy ratio is 316, 317L. More price advantage, reducing equipment manufacturing costs. In terms of corrosion resistance, especially in the medium environment (such as seawater, high chloride ion content), the resistance of pitting, crevice corrosion, stress corrosion and corrosion fatigue of duplex stainless steel is better than ordinary austenite. Stainless steel, comparable to high-alloy austenitic stainless steel.
Due to the special performance characteristics of 2205 duplex steel, the product types include bar, wire, welded pipe, seamless pipe, steel plate, forged material, strip, etc., which have a wide range of applications and are by far the most widely used grade in duplex steel. .
