Understand 2205 stainless steel’s two big characteristics, helps everybody better application. Mechanical machinability: In high-speed machine tools, 2205 alloy feed rate and cutting speed and 316L is the same. If the use of carbonized knife, cutting speed compared with 316L reduced by about 20% , the performance of machinery and equipment and its parts play a key role here. Welding: The weldability of 2205 alloy is good. 2205 alloy to achieve the performance of the welding metal and hot modified parts and still maintain the same corrosion resistance, strength and toughness of the base metal. 2205 is not difficult to weld, but it is necessary to design its welding program so that it can keep good phase equilibrium state after welding and avoid harmful metal phase or non-metal phase precipitation. 2205 stainless steel features: 1.2205 duplex stainless steel alloy compared with 316L and 317L Austenitic stainless steel, 2205 alloy is superior in corrosion resistance to pitting and crevice corrosion, it has high corrosion resistance, compared with Austenite, it has lower Coefficient of thermal expansion and higher thermal conductivity. 2. The dual phase stainless steel 2205 has twice the compressive strength of the AUSTENITIC stainless steel and is lighter than 316L and 317L. Alloy 2205 is particularly suitable for use in a temperature range of 50 ° F/+ 600 ° F, under restricted conditions (especially for welded structures) and at lower temperatures. I hope this helps.
