Theory for Alloys
(1) Al in the material can react with O in the air to form Al2O3 protective film, which is anticorrosive and corrosion resistant.
②Cr and Mo ions in seawater can automatically supplement the gap formed by Cl- ions on steel pitting corrosion, forming a dense [TJC STEEL]protective layer, preventing the pitting corrosion from developing to depth, so as to achieve the effect of corrosion resistance and prolong service life.
10CrMoAl steel has the characteristics of relatively simple production process, good comprehensive mechanical properties [TJC STEEL]and welding properties, and corrosion resistance to sea water. It is the most ideal pipeline and processing material for conveying water, oil and gas and medium containing sea water in coastal power plants, coastal oil fields, coastal natural gas and petrochemical plants.
