CORROSION BEHAVIOR OF 18% Ni M250 GRADE MARAGING STEEL UNDER WELD-AGED CONDITION IN SULFURIC ACID MEDIUM

Microstructural characterization of grade 300 and grade 350 maraging steels and electrochemical study in hydrofluoric solution

“…Sanatkumar et al [11] and Kumar [12] studied welded grade 250 maraging steel in different concentrations of hydrochloric acid (HCl) solutions. They used the polarization and electrochemical impedance techniques and found that as the acid concentration increases, the aged steel has less corrosion resistance and the corrosion rate increases, but the corrosion potential shifts to less negative values.…”

Corrosion inhibition of high strength maraging steel by cerium(III) ions in sulfuric acid solution

“…The corrosion and corrosion protection of maraging steels in different media have been investigated by many researchers . It has been reported that maraging steels show better corrosion resistance in acidic solutions compared to tempered martensite alloy steels.…”

“…The corrosion and corrosion protection of maraging steels in different media have been investigated by many researchers . It has been reported that maraging steels show better corrosion resistance in acidic solutions compared to tempered martensite alloy steels. The corrosion of maraging steels in acidic solutions results mainly during the acid cleaning, where the scales and corrosion products that form on the steel surface and cause a negative effect on the performance of the steel equipment must be cleaned using an acidic pickling solution.…”

“…It is well known that the purpose of adding a corrosion inhibitor within the acidic pickling solution is to eliminate the effect of acid in attacking the surface of steel, which in turn decreases the corrosion process . In recent years, besides the efficiency of the inhibitor, another important factor has to be taken into account to choose the suitable inhibitor.…”

Effects of Immersion Time and 5‐Phenyl‐1H‐tetrazole on the Corrosion and Corrosion Mitigation of Cobalt Free Maraging Steel in 0.5 M Sulfuric Acid Pickling Solutions

“…Maraging refers to the ageing of martensite, which is easily obtained at normal cooling rates due to the high nickel content [2]. The ultrahigh strength of maraging steels results from the precipitation of intermetallic compounds during the ageing process at about 480 ∘ C [3][4][5][6]. Maraging steels have been widely used in many tooling applications including missile and rocket motor cases, aircraft, aerospace, wind tunnel models, landing gear components, high performance shafting, gears, fasteners, and nuclear and gas turbine applications.…”
