The corrosion data in this section is mainly based on the results of general corrosion laboratory tests, which are not strictly comparable with actual service conditions.The corrosion tables provide an initial guide to the selection of materials and are intended to facilitate understanding of the different types of corrosion damage that can arise due to poor material selection.

Hastelloy C-276, UNS N10276 or W.Nr. 2.4819, is the most universally corrosion-resistant nickel alloy. It is widely used in various applications involving sulfuric acid of an extensive range of concentrations and temperatures.
Impervious graphite corrosion resistance - GAB NeumannGraphite is corrosion-resistant against most common acids (e.g. hydrochloric acid, sulfuric acid, and hydrofluoric acid) and solvents. It has limited resistance against oxidizing media (e.g. nitric acid) and bases (e.g. amines, potash and caustic soda).

AbstractIntroductionSulfuric Acid Corrosion Model For ConcreteMaterials and MethodsResults and DiscussionConclusionsData AvailabilityAcknowledgmentsThis paper chooses the apparent diffusion coefficient for OH (hydroxyl ion) for concrete as an index to evaluate the corrosion degree of concrete subjected to sulfuric acid. Based on the reaction boundary layer theory, a sulfuric acid corrosion model for concrete was established and verified through experiments. The experiment design and data processing of sulfuric acid corrosion tests for concrete were carried out using uniform test design and nonparametric regression. Effects of water-cement ratio Selection of stainless steels for handling sulphuric acid Aeration or the presence of oxidising agents in sulphuric acid contributes to the corrosion resistance of stainless steels. Stainless Steels have lower resistance to de-aerated sulphuric acid. Reducible ions such as Fe 3+, Cu 2+, Sn 4+ are effectively oxidising agents and can reduce corrosion if present in the acid.

Sulphuric acid Sandvik Materials TechnologySulphuric acid These corrosion data are mainly based on results of general corrosion laboratory tests , carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen).
Feb 11, 2002 · Sulfuric Acid. ium exhibits resistance to corrosion by dilute solutions of pure sulfuric acid at low temperatures. Unalloyed titanium is resistant to concentrations of about 20% sulfuric acid at 32 °F (0 °C). This drops to around 5% acid at room temperature. Grade 7 alloy is resistant to approximately 45% acid at room temperature.
uPVC Chemical Resistance Chart - MarleyClass 1:HIGH RESISTANCE (corrosion-proof) - all materials belonging to this class are completely or almost completely corrosion-proof against the conveyed fluid, according to the specified operating conditions. Class 2:LIMITED RESISTANCE - the materials belonging to this class are partially attacked by the conveyed chemical compound.Alloy selection for service in sulphuric acidTypes 316 and 316L, are generally resistant to strong sulphuric acid at ambient temperature and, unlike carbon steel and cast iron, resist erosion-corrosion. Corrosion resistance of these grades is good up to about 6 m/s (20 ft/s) in the absence of abrasive particles (although normal design would be limited to about 2-3 m/s [6.5-10 ft/s]).
