What is BS 6533 – Steel by etching about?
BS 6533 is a British standard that discusses the guide to macroscopic examination of steel by etching with strong mineral acids. Etching is used to reveal the microstructure of the metal through a selective chemical attack. It also removes the thin, highly deformed layer introduced during grinding and polishing. BS 6533 gives guidance on and describes methods for the macroscopic examination of steel by etching with strong mineral acids. The methods given have very wide applications. Selection of the type and concentration of the reagent, the temperature of the reagent and the conditions of surface preparation of the test piece make it possible to achieve an informed description of the etched surface.
