Description of 2205 stainless steel plate

2205Duplex Stainless Steel or 2205 alloy is a duplex stainless steel made of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy and others. It has high strength, good impact toughness and good overall and local resistance to stress corrosion.

Application of duplex stainless steel plate

Widely used in petrochemical equipment, seawater and wastewater treatment equipment, oil and gas pipelines, paper machinery and other industrial fields, in recent years has also been used in the field of bridge load-bearing structure, with good prospects for development.


Features about 2205 stainless steel machining


2205 duplex stainless steel thermoforming

  • We recommend forming should be done below 600 ° F. During thermoforming, the entire workpiece should be heated as a whole, at a temperature in the range of 1750 ° F to 2250 ° F, and the 2205 duplex is very soft at this temperature. If the temperature is too high, 2205 alloy easy to hot tear. Below this temperature austenite breaks.
  • Below 1700 ° F, intermetallic phases quickly form due to temperature and strain. Immediately after thermoforming is completed, it is subjected to solid solution annealing at a minimum temperature of 1900 ° F and quenched to restore its phase balance, toughness, and corrosion resistance. We do not recommend stress relief, but if this is necessary, the material should be solution annealed at a minimum temperature of 1900 ° F and then rapidly cooled for water quenching.

2205 duplex steel cold forming

2205 duplex stainless steel for cutting and cold forming. However, due to its high strength and hardness, the 2205 alloy requires more cold forming than austenitic steel, and because of its high strength, it must take full account of the rebound factor.

2205 stainless steel plate heat treatment

2205 Duplex steel should be annealed at a temperature of 1900 ° F minimum, then rapidly cooled for water quenching. This treatment applies to solid solution annealing and stress relieving. Strain relief treatment, such as at temperatures below 1900 ° F, tends to result in the precipitation of unwanted metal or non-metal phases.

2205 stainless steel mechanical cutting

On high-speed machine tools, 2205 stainless steel feed rate and cutting speed and 316L stainless steel are the same. With carbonized knives, the cutting speed is reduced by about 20% compared to 316L, where the performance of the machine and its components plays a key role.

2205 stainless steel welding performance

2205 stainless steel weldability is very good. 2205 duplex stainless steel pipe to achieve the performance of the weld metal and thermal deterioration of the base metal and still maintain the same corrosion resistance, strength, and toughness. 2205 duplex stainless steel welding is not difficult, but the need to design the welding process, so that after welding, you can maintain a good phase balance, to avoid harmful metal phase or non-metallic phase precipitation. 2205 can be welded in the following equipment: GTAW (TIG); GMAW (MIG); SMAW ("stick" electrode); SAW; FCW; and PAW.
