| titleOfInvention | A kind of steel grain size erosive agent and its application |
| abstract | The present invention provides a steel grain size etchant and application thereof. The etchant of the present invention adopts aromatic nitro compound, surfactant and diluent, wherein, on a mass basis, aromatic nitro compound and surfactant The component ratio of 1:1 ~ 1:2. The aromatic nitro compound is p-nitrobenzoic acid and/or 2-nitrobenzoic acid. The surfactant is any one or a combination of sodium lauryl sulfate, sodium aliphatic alcohol polyoxyethylene ether sulfate, dodecylbenzene sulfonic acid, lauryl alcohol amide, and nonylphenol polyoxyethylene ether. The diluents are water and glycerin. The erosive agent of the invention does not contain toxic and explosive picric acid, avoids environmental pollution and affects public safety, and meets environmental protection requirements. In addition, the etchant provided by the present invention can clearly display the grain boundaries of large grains, small grains and mixed grains of the sample, the grain size is clear and complete at 100 times, and the grain size rating is easy, and the effect is good . |
