GB/T 226-2015 Translated English of Chinese Standard. (GBT 226-2015, GB/T226-2015, GBT226-2015): Test Method for Macrostructure and Defect of Steel by Etchinghttps://www.chinesestandard.net, 2 ago 2016 - 11 páginas This Standard specifies the hot acid etching method, cold acid etching method (including dendrite corrosion method), and electrolytic etching method, which test the macrostructure and defect of steel. This Standard is applicable to the acid etching test of the macrostructure and defect of steel. Other material acid etching test can be implemented as per this Standard. |
