2205 Duplex Stainless Steel Plate Standard Width 1000 1219 1500mm
Product Description
2205 duplex stainless steel is a nitrogen added duplex stainless steel (referred to as 2205 duplex steel). Duplex stainless steel 2205 alloy is a composite stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel nitrogen alloy.
At present,2205 stainless steel products include 2205 stainless steel pipe and 2205 dual phase stainless steel seamless pipe; 2205 duplex stainless steel plate, 2205 stainless steel bar, forged material, pipe fittings, strip, etc. Early dual phase stainless steel can resist uniform corrosion of medium strength and chlorine stress corrosion fracture, but its performance will be greatly reduced when it is used in welding. In order to improve this situation, nitrogen is added to the duplex stainless steel 2205, which not only improves the corrosion resistance, but also has a good welding performance. Due to the special performance characteristics of 2205 dual phase steel, it has a wide range of applications and has been widely used.
performance
Mechanical properties:
In the same temperature range of - 50 ° C - 280 ° C, duplex stainless steel has good mechanical properties. When duplex steel is subjected to a high temperature of more than 300 ° C for a long time, its micro-computer structure will change and the content of austenite steel will be changed. Compared with the austenitic steel, the duplex steel and super duplex steel have similar pitting and crack corrosion resistance, but generally have excellent resistance to stress corrosion and organic acid corrosion. In the industry, it is well known that pitting resistance is expressed by pitting resistance equivalent value.
Mechanical machinability:
On high-speed machine tools, the feed rate and cutting speed of 2205 alloy are the same as that of 316L. If the carbonized knife is used, the cutting speed is reduced by about 20% compared with 316L. The performance of the machine and its components plays a key role here.
Heat treatment performance:
Alloy 2205 shall be annealed at a minimum temperature of 1900 ° F, then rapidly cooled and water quenched. This treatment shall be applied to solid melt annealing and stress relief. If the stress relief treatment is performed at a temperature lower than 1900.it is easy to cause the precipitation of harmful metal or nonmetallic phases.
