Macroetch Examinations Macroetching, also known as deep etching, involves etching specimens prepared with a suitable acid or reagent for macrostructural examination at low magnifications and rating by a astm e340 series of photographs showing the incidence of certain conditions such as: Forge shops, in addition, use macroetching to reveal flow lines in setting up the best forging practice, die design, astm e340 metal flow.

Other applications of macroetching include: The copper industry uses macroetching for control of surface porosity in wire bar.

The metallurgical engineering team at SGS MSi has the expertise to meet all your material requirements for acid etch processes. Development of grain flow in astm e340 forged part qstm fastener, which is a critical property for the integrity of the forging.

Macroetch Examinations

Macroetching will also show the astm e340 of discontinuities and voids, such as seams, laps, porosity, flakes, bursts, extrusion rupture, cracks, and so astm e340. The most common reagent for macroetching iron and steel is a 1: Study of weld structures, definition of weld penetration, dilution of filler metal by base metals, entrapment of flux, porosity, and cracks in weld and heat affect zones, etc.
