    Selection Stainless Steel For Handling Hydrochloric Acid HCl. Higher grades of stainless steel can have limited resistance, up to around 3% maximum at ambient temperatures, but may suffer local attack mainly as crevice and pitting corrosion, even at such low concentrations. The steep curves for 316 and the higher alloyed grades on the iso-corrosion diagram illustrate their very limited resistance.Some results are removed in response to a notice of local law requirement.

  14. Corrosion resistance, Outokumpu

    Stainless steel is normally considered to be resistant to uniform corrosion in a specific environment if the corrosion rate does not exceed 0.1 mm/year. Resistance to uniform corrosion generally increases with increasing levels of chromium, nickel, and molybdenum.

  15. Sulfuric Acid - Rolled Alloys, Inc.

    Depending on acid concentration and the metal involved, sulfuric acid can behave as either a reducing acid or an oxidizing acid. In lower concentrations (up to about 70%) and temperatures on steel or stainless steel, it is reducing. At concentrations over 70%, and into the oleum range, the acid is oxidizing to steel and stainless steel.Some results are removed in response to a notice of local law requirement.

    Ferritic stainless steels (Table 2) are straight-chromium 400 Series types that cannot be hardened by heat treatment, and only moderately hardened by cold working. They are magnetic, have good ductility and resistance to corrosion and oxidation. Type 430 is the general-purpose stainless of the ferritic group. Table 2 FERRITIC STAINLESS STEELS TYPE

    The resistance of austenitic stainless steels to tetraoxosulphate (VI) acid is complex due to the active passive nature of the alloys. Any compound capable of donating free chlorine ions (Cl-) to an aqueous (water-based) solution has the potential for causing failure in austenitic stainless steels.

  24. Corrosion of Stainless Steel - damstahl.com

    The excellent corrosion resistance of stainless steel is caused by a very thin layer of oxides in particu- lar chromium and iron oxides, and despite a thickness of only a few nanometers, this oxide layer is so strong that it effectively isolates the steel from the environment. Should the oxide layer suffer from a

  25. Stainless Steel Corrosion Data, Just Mfg

    The ability of stainless steels to resist corrosion is related to the chromium content, for chromium is the alloying element that endows stainless steels with their corrosion resistance. By combining with oxygen, chromium forms a thin but transparent chromium-oxide surface protective film.

  26. Nitric vs Citric Acid Passivation - Advanced Plating ...

    Jul 11, 2019 · Proper passivation of stainless steel with an oxidizing acid such as nitric or citric acid removes this free iron and promotes the growth of a thin, dense protective oxide layer which maximizes the corrosion resistance of the stainless steel. Depending on the type of stainless steel and end application certain passivation processes may perform better at passivating than others.
