Stainless Steel Steel ... This will ultimately be decisive in global phosphate pricing, with China set to continue its role as the global marginal/swing producer. Given WengfuKailin's control of the domestic phosphate rock market, its rock pricing strategy will ultimately be a major factor in marginal cost levels within China, and therefore ...
Its available P2O5 content ranges from 18 to 22 percent, depending on the grade of rock and the free -moisture content of the final product. The process consists of mixing finely ground phosphate rock containing 32 percent or more P2O5 with sulfuric acid (55° B.) in the ratio of 100 parts of rock to 85 parts of acid.

Highly alloyed stainless steel UNS N-08028 plates (1 × 1 cm 2), commercially named Sanicro 28, were used for this study. The chemical composition of Sanicro 28 SS is given in Table 1. The samples and electric contacts (copper wire) were embedded in an epoxy resin (Epofix, Struers, France) to avoid crevice corrosion during the immersion.

Chloride stress corrosion is a type of intergranular corrosion and occurs in austenitic stainless steel under tensile stress in the presence of oxygen, chloride ions, and high temperature. It is thought to start with chromium carbide deposits along grain boundaries that leave the metal open to corrosion.
