Schiff Bases Derived from Triazoles as Corrosion Inhibitors for Maraging Steel in Acid Mixtures: Experimental and Theoretical Studies
2023, Polycyclic Aromatic CompoundsA critical review on susceptibility of stress corrosion cracking in maraging steel weldments
2019, Materials Today: ProceedingsCitation Excerpt :The material has been tested for 25 days and it has found that there were no decrease in stress intensity value for hydraulic oil compare to water. The microstructure of oxides forms on steam at a certain temperature on maraging steel was established, which is beneficial for SCC resistance [21]. It has been observed that the steam therapy offers higher resistance to maraging steel than standard manganese phosphate therapy because subsequent therapy makes steel more susceptible to SCC [22].
Modelling of corrosion fatigue crack initiation on martensitic stainless steel in high cycle fatigue regime
2018, Corrosion ScienceCitation Excerpt :AES Measurements were performed at ten different locations on the specimen surface in order to evaluate the thickness uniformity of the passive film. The half of the oxygen content in the passive film is considered [44,45] as the corresponding thickness of passive film (see Fig. 3) and was found to be uniform on the specimen surface. Its value is around 3 nm for the passive film formed in air.
Simultaneous ageing and plasma nitriding of grade 300 maraging steel: How working pressure determines the effective nitrogen diffusion into narrow cavities
2017, Surface and Coatings TechnologyCitation Excerpt :Maraging steels show exceptional strength to toughness ratio, good machinability and weldability and ease of heat treatment. Moreover, the retention of their mechanical properties after long operative times at medium-high temperatures can be outlined as one of the most interesting characteristics [1–4]. These properties can be explained by the particular chemical composition of these alloys and its hardening treatment.
Microstructure and corrosion behaviour of gas tungsten arc welds of maraging steel
2015, Defence TechnologyCitation Excerpt :Jha et al. [10] studied SCC of maraging steel and found that an intergranular mode of cracking occurs. Study made on 250 grade maraging steel at elevated temperature in steam has shown that it offers better protection compared to manganese phosphate treatment [11]. SCC susceptibility of steel was caused by acid dip step in the pretreatment of phosphating process [12].
