It has a strong resistance to chloride stress corrosion cracking, high thermal conductivity and low thermal expansion coefficient. The high chromium, molybdenum and nitrogen content it has a high resistance to pitting, crevice corrosion and general corrosion. The impact strength is also high, and inappropriate for the 2507 alloy used in a temperature environment higher than 570 ℃, a long time in such an environment, its toughness will be reduced. Its chemical composition and mechanical properties as shown in Tables 1 and 2. http / / www.hshjxs.com
