The corrosivity of sulfuric acid depends on many factors including temperature, concentration, the presence of oxidizing or reducing impurities, velocity effects, and solids in suspension. For 90% to 100% sulfuric acid, a good choice would be 316L stainless steel.

Legend A = No Attack, possibly slight absorption. Negligible effect on mechanical properties. B = Slight attack by absorption. Some swelling and a small reduction in mechanical likely. C = Moderate attack of appreciable absorption. Material will have limited life. D
The additon of sulfur bridges is a crosslinking technique which can render a material chemically resistant and thermally stable. However, if you had added to much sulfuric acid, you would have crosslinked the rubber so much it would have became brittle.
Findings The paper shows that geopolymer cement with 1 wt.% addition of nano-silica were highly resistant to sulfuric and hydrochloric acid. The strength increase was contributed by the densifiion of the microstructure with the addition of nano-silica.
Quartz Heater for Acid Solutions Click to enlarge For acidic solutions, quartz or PTFE (Teflon®) coated immersion heaters are used. Quartz heaters are resisting pH solutions from 0 to 7, except Hyrdrofluoric acids and caustics. For Hydrofluoric acids of less than

8/7/2020· These provide a simple, moderately corrsion resistant, airtight seal. Air is pumped in by water hose adapted for the aquarium aerator with PVC tubing. To keep the lid on the bucket a weight will be needed proportional to the area of your bucket lid and the pressure you want the output to be at.
ALKYL SULFONIC ACIDS, LIQUID, WITH MORE THAN 5% FREE SULFURIC ACID are strong acids. They react exothermically with chemical bases (for example: amines and inorganic hydroxides) to form salts. The reactions can generate dangerously large amounts of heat in small spaces.

830 for sulfuric acid, and 1832 for spent acid. Tank cars when received will frequently be under pressure because of thermal expansion of the acid or slow hydrogen generation. The pressure in the tank car must first be released by carefully and slowly removing the one-inch plug from the safety vent and by slowly opening the one-inch pressure release valve.
