Use environment:
The higher chromium and molybdenum content of 2507 dual-phase steel makes it have strong resistance to organic acids such as formic acid and acetic acid. 2507 dual-phase steel also has strong corrosion resistance to inorganic acids, especially those containing chlorides. Compared with 904L, 2507 duplex steel has stronger corrosion resistance to diluted sulfuric acid mixed with chloride ions. 904L is an austenitic alloy, designed to resist pure sulfuric acid corrosion. 316L can not be used in hydrochloric acid environment, it may be subject to local corrosion or overall corrosion. 2507 duplex steel is used in diluted hydrochloric acid environment, and has strong resistance to pitting corrosion and crevice corrosion.
Application areas:
Petroleum and natural gas industry equipment; offshore platforms, heat exchangers, underwater equipment, fire fighting equipment; chemical processing industry, utensils and pipeline industry; desalination, high-pressure RO equipment and submarine pipelines; energy industry such as power plant desulfurization and denitrification FGD system, industrial scrubbing system , Absorption tower; mechanical parts (high-strength, corrosion-resistant, wear-resistant parts).
