2205 material is austenitic-ferritic stainless steel (duplex steel), which is a duplex stainless steel.
2205 duplex steel is a composite stainless steel composed of 21% chromium, 2.5% molybdenum and 4.5% nickel-nitrogen alloy. Due to the special performance characteristics of 2205 duplex steel, it has a wide range of applications. It is currently the most widely used duplex steel. brand number. Duplex steel properties: resistance to pitting corrosion and crevice corrosion.
2205 stainless steel plate is a duplex stainless steel. The advantage of this kind of steel plate is high temperature resistance. So what is the temperature resistance of 2205 stainless steel? The maximum operating temperature of 2205 stainless steel plate is 750-860 degrees, but it is actually not as high as 860 degrees. There is a critical point at 450 degrees. It is difficult to maintain the 2205 stainless steel plate at 450 to 860 degrees, because when it is above 450 degrees, the chromium around the carbon will be diluted, forming a carbonized chromium, resulting in a chromium-depleted area, thereby changing the performance of the stainless steel material; and the temperature of 450 degrees plus the yield force will Transform austenite to martensite. Its service life is 5 times that of traditional centrifugally cast pipes.
2205 stainless steel plate is a material that is produced by various brands. When making steel, the chemical composition of the material is the same. As long as it meets the national standard, it is very durable. This alloy is especially suitable for -50°F/+600 °F temperature range.
