Nr 1.4462 corrosion resistance to uniform corrosion due to the chrome content (22%), molybdenum (3%) and nitrogen content (0.18%), anti-corrosion properties of 2205 is better than in most environments 316L and 317L. Local anti-corrosion content 2205 in chromium, molybdenum and nitrogen oxidation resistance and make it acidic solutions, pitting and crevice corrosion has a strong resistance. Resistance to stress corrosion of stainless steel duplex microstructure helps to improve resistance to stress corrosion cracking of stainless steel capacity. At a certain temperature, should be tension, under the presence of oxygen and chlorides, austenitic stainless steel to chloride stress corrosion will occur. Because these conditions are difficult to control, therefore 304L, 316L and 317L of limited use in this regard. 2205 steel corrosion fatigue strength and high corrosion resistance has a high resistance to corrosion fatigue strength. Processing equipment susceptible to corrosive environments and load cycle, the 2205 feature is ideal for such applications. The chemical composition of the structure in 2205 through 1900 ° / 1922 ° F (1040 ° / 1080 ° C) solution annealing treatment, obtain the ideal microstructure 50 α / 50 γ. If the heat treatment temperature is higher than 2000 ° F, may increase the ferrite component. Like other duplex stainless steels, 2205 is susceptible to precipitation of intermetallic phases. Intermetallic phases between 1300 ° F and 1800 ° F precipitation at 1600 ° F temperature, the precipitation of the fastest. Therefore, we need to test 2205, to ensure that no metal phase ,, between test reference ASTM A 923. We recommend forming thermoforming process should be at 600 ° F below the temperature. When hot forming, the workpiece should be heated uniformly, should be 1750 ° F to 2250 ° F within a temperature range of 2205 alloy is very soft at this temperature. If the temperature is too high, the 2205 is easy to hot tearing. If below this temperature, the austenite would fracture. Below 1700 ° F, due to the influence of temperature and deformation, the formation of intermetallic phases quickly. Thermoforming is done, it should immediately be solution annealed at 1900 ° F minimum temperature, and quench to restore phase balance, toughness, and corrosion resistance. We do not recommend stress relief, but if you must do so, the material should be solution annealed at 1900 ° F minimum temperature and then rapidly cooled by water quenching. Cold forming 2205 can be cut and cold forming. However, since 2205 its high strength and hardness, it is more needed than the austenitic steel cold forming, but also because of its high strength, taking fully into account springback. 2205 heat treated alloy should be annealed at 1900 ° F minimum temperature and then rapidly cooled by water quenching. This treatment applies to solution annealing and stress relief. Stress relief treatments at temperatures below 1900 ° F carry the risk of detrimental metal or non-metal phase precipitation. Mechanical machinability on high-speed machines, feed rate and cutting speed 2205 and 316L is the same. If charring knife, cutting speed and 316L reduced by about 20% compared to the performance of machinery and equipment and its components play a key role in this. Welding 2205 possesses good weldability. 2205 is to be achieved performance for weld metal and heat affected zone and the base metal remains the same corrosion resistance, strength and toughness. Welding 2205 is not difficult, but necessary to design welding procedures for welding, can maintain a good phase balance, avoid precipitation of detrimental intermetallic or nonmetallic phases of. 2205 can be welded in the following devices: GTAW (TIG); GMAW (MIG); SMAW ("stick" electrode); SAW; FCW; and PAW 2205 duplex stainless steel 2205 is 21% chromium, 2.5% molybdenum and Duplex 4.5% of nickel, nitrogen alloyed stainless steel.
