| titleOfInvention | Austenitic stainless steel stress corrosion inhibitor and preparation method thereof |
| abstract | The invention provides an austenitic stainless steel stress corrosion inhibitor and a preparation method thereof, which relate to the field of metal corrosion inhibition and comprise the following components: 5-90% of thiosulfate, 5-90% of a component A, 1-80% of a component B and 1-50% of organic sulfonate; the component A is any one composition selected from a composition of phosphate and silicate, a composition of phosphate and sulfate and a composition of phosphate, silicate and sulfate; the component B comprises molybdate and tungstate. The austenitic stainless steel stress corrosion inhibitor can effectively inhibit chloride stress corrosion cracking of austenitic stainless steel in a chloride aqueous solution, has the characteristics of excellent inhibition effect, small dosage, low cost, low toxicity, no peculiar smell, simple and convenient field operation and the like, and is suitable for various chloride-containing acidic water, circulating water and pickling processes of chemical devices. In addition, a preparation method of the austenitic stainless steel stress corrosion inhibitor is also provided. |
