Five: Overview. Corrosion resistance and main use environment: The high chromium and molybdenum content of 2507 duplex steel makes it have a strong ability to resist the overall corrosion of organic acids such as formic acid and acetic acid. 2507 duplex steels also have strong resistance to corrosion of inorganic acids, especially those containing chlorides.

Compared to 904L, 2507 duplex steel is more resistant to corrosion of diluted sulfuric acid mixed with chloride ions. 904L is an alloy in austenitic state, designed to resist pure sulfuric acid corrosion. 316L cannot be used in hydrochloric acid environments, where it may be subject to localized or overall corrosion.

2507 duplex steel is used in diluted hydrochloric acid environment, which has strong resistance to pitting corrosion and crevice corrosion.

2507 stainless steel is a ferritic-austenitic (duplex) stainless steel, which combines the beneficial properties of many ferritic steels and austenitic steels, due to the high content of chromium and molybdenum in this steel, it has good resistance to pitting corrosion, crevice corrosion and uniform corrosion. The duplex microstructure guarantees a high resistance to stress corrosion cracking and a high mechanical strength.

(S32168) 06CR18Ni11Ti belongs to the national standard NB austenitic stainless steel.

S32168) 06Cr18Ni11Ti austenitic stainless steel has good corrosion resistance in the atmosphere, and is widely used in petrochemical, electric power, bridge and automobile industries. However, the "stainless steel" of stainless steel is not absolute, and due to the special service environment, stainless steel will also corrode. Factors such as medium concentration, pH value, and temperature will have a great impact on the corrosion resistance of stainless steel.

Ferritic stainless steel.

Chromium content 15% 30%. Its corrosion resistance, toughness and weldability improve with the increase of chromium content, and the chloride stress corrosion resistance is better than that of other types of stainless steel, which belong to this category of CRL7, CR17MO2TI, CR25, CR25MO3TI, CR28, etc. Because of its high chromium content, ferritic stainless steel has good corrosion resistance and oxidation resistance, but poor mechanical and technological properties, and is mostly used in acid-resistant structures with little stress and as oxidation-resistant steel.
