2507 is a ferritic austenitic stainless steel, which is a type of stainless steel, also known as super duplex stainless steel. It combines both ferritic stainless steel and austenitic stainless steel. This stainless steel chromium and molybdenum content is relatively high, so the corrosion resistance will be more prominent, and the strength is good. It is composed of chromium, nickel, molybdenum and so on. 2507 this stainless steel is used in the oil industry or natural gas industry, mainly combined with its corrosion resistance and anti-cracking performance, in addition to the fire protection system or water spraying system, you need this high strength, but also to the corrosion resistance of stainless steel, to be able to meet the application standard. Austenitic steel has good corrosion resistance, good comprehensive mechanical properties and process properties, but low strength and hardness.
