1.441  steel
Duplex stainless steel Material number 1.441
Material number 1.441 equal material :AISI 2507 ,X2CrNiMoN25-7-4,S32750
Material number 1.441 introduction :
Material number 1.441 is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and a low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion.
Material number 1.441 product form :
steel plate, steel pipe , steel coil, steel bar
Material number 1.441 characteristics :
Material number 1.441 Duplex is highly resistant to uniform corrosion by organic acids such as formic and acetic acid. It is also highly resistant to inorganic acids, especially if they contain chlorides.  Alloy Material number 1.441 is highly resistant to carbide-related intergranular corrosion.  Due to the ferritic portion of the duplex structure of the alloy it is very resistant to stress corrosion cracking in warm chloride containing environments. Through additions of chromium, molybdenum and nitrogen localized corrosion such as pitting and crevice attack are improved.  Alloy Material number 1.441 has excellent localized pitting resistance.
Material number 1.441 application :
Desalination Equipment
Chemical process pressure vessels, piping and heat exchangers
Marine Applications
Flue Gas Scrubbing Equipment
Pulp & Paper Mill Equipment
Offshore Oil production/technology
Oil and gas industry equipment
