Process

Hot forming

We recommend that the forming should be carried out at temperatures below 600°F as far as possible. During the thermoforming process, the whole workpiece should be heated as a whole and should be carried out in the temperature range of 1750°F to 2250°F, at which temperature 2205 alloy is very soft. If the temperature is too high,2205 alloy is prone to thermal tearing. If the temperature is lower than this, the austenite will fracture. Below 1700°F, due to the influence of temperature and deformation, the intermetallic phase quickly forms. Immediately after the thermoforming is completed, it should be annealed 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 it must be done, the material should be annealed in solid solution at a minimum temperature of 1900°F and then quickly cooled for water quenching.

Cold forming

2205 alloy can be cut and cold formed. However, due to the high strength and hardness of 2205 alloy itself, it needs to be cold-formed more than austenitic steel, and because of its high strength, the springback factor should be fully taken into account.

Heat treatment

The 2205 alloy should be annealed at a minimum temperature of 1900°F and then quickly cooled for water quenching. This treatment is used for solid solution annealing and stress relief. Stress relief treatment, if performed at temperatures below 1900°F, tends to lead to the precipitation of harmful metallic or non-metallic phases.

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, and the performance of the machine equipment and its components plays a key role in this.

weld

2205 alloy has good weldability. The properties to be achieved by 2205 alloy are that the welding metal and the heat-deteriorated part still maintain the same corrosion resistance, strength and toughness as the base metal. 2205 welding is not difficult, but it is necessary to design its welding procedure, so that after welding, it can maintain a good phase balance state and avoid harmful metal phase or non-metal phase precipitation. 2205 can be welded in: GTAW (TIG); GMAW (MIG); SMAW (“stick” electrode); SAW; FCW; and PAW

2205 stainless steel

Features:

1. Duplex stainless steel 2205 alloy compared with 316L and 317L austenitic stainless steel,2205 alloy in the corrosion resistance and crevice corrosion performance is better, it has a high corrosion resistance, compared with austenite, its coefficient of thermal expansion is lower, higher thermal conductivity.

2.Duplex stainless steel 2205 alloy compared with austenitic stainless steel, its compressive strength is twice its, compared with 316L and 317L, the designer can reduce its weight. The 2205 alloy is particularly suitable for use in the -50 °F/+600°F temperature range and can also be used at lower temperatures under strict restrictions (especially for welded structures)
