Determination of Alloying and Impurity Elements from Matrix and Inclusions from a Process Sample of a Double Stabilized Stainless Steel

Abstract

The determination of alloying and impurity elements was performed from a stainless steel matrix and inclusions in process samples. An electrolytic extraction method was applied for the separation of inclusions using two different but commonly used electrolytes, 10% HCl and 10% acetylacetone in methanol. The elemental analyses were performed using atomic absorption spectrometry. The elements of interest were aluminum, arsenic, copper, vanadium, titanium and chromium. The aluminum containing inclusions were imaged using a field emission scanning electron microscope. The results for copper and chromium in both electrolytes, vanadium in 10% HCl electrolyte and arsenic in 10% acetylacetone electrolyte were in good agreement with industrial data. Titanium and aluminum were measured from the dissolved steel matrix but titanium was also detected in the inclusions. It was concluded that the analytical results for titanium and aluminum measured using an optical emission spectrometer is affected by the inclusions within the stainless steel.

Kinetics of Arsenic Surface Segregation in Scrap-Based Silicon Electrical Steel

“…It is well known that routinely manufactured steel using recycled scrap leads to an overall increase in the impurity concentrations of Cu and Sn, in particular, though the presence of other impurities, like As and Sb, is not negligible [9][10][11][12]. Although there is a great deal of knowledge about residual Cu and Sn in steel, a shortage of recent studies on other, less common elements at residual levels has been identified [8].…”

“…Arsenic (As) can originate from several resources, such as complex iron ore, scrap steel, ferroalloys, and other furnace charges [9][10][11]. The effects of residual element As on the properties of steels are receiving more and more attention [9,[11][12][13][14][15][16][17].…”

“…A study of the literature [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] shows that the effects of As on the properties of iron alloys and steels have been studied for contents ranging from 0.002 to 10.0 wt % As, whereas surface-science investigations on As segregation behavior were predominantly focused on As contents ranging from 0.005 to 0.05 wt % As in polycrystalline samples and single crystals. High temperature annealing studies have shown that the segregation of S is highly favored over the segregation of As [23,24].…”
