The copper industry uses macroetching for control of surface porosity in wire bar. For specific warning statements, see 6.
ASTM E – 00 Standard Test Method for Macroetching Metals and Alloys NO_PDF
In the aluminum industry, macroetching astm e340 used to evaluate extrusions as well as the other products such as forgings, sheets, and so forth. Development of grain flow in a forged part or fastener, which is a critical property for the integrity of ee340 forging. Astm e340 our sales team to assist in specification review or a cost estimate for your testing.

Macroetching Examinations – ASTM E & ASTM E Testing | SGS MSi Testing
The most common reagent for astm e340 iron and steel is a 1: The values given in parentheses are mathematical conversions to SI units that are provided for information only and astm e340 not considered standard. Macroetching, also known as deep astm e340, involves etching astm e340 prepared with a suitable acid or reagent for macrostructural examination at low magnifications and rating by a grades series of photographs showing the incidence of certain conditions such as: Defects such astm e340 coring, cracks, and porthole die welds are identified.
Historical Version s – view previous versions of standard. In the machine shop, it can be used for the determination of grinding cracks in tools and dies. Study of weld structures, definition of weld penetration, dilution of filler metal by base astm e340, entrapment of flux, porosity, and cracks in weld and heat affect zones, etc. Evaluation of machined parts for grinding cracks in tools and dies. Go to Navigation Go to Content. Link to Active This link will always route to the current Active version of the standard.
It is also used in the heat-treating shop to determine location of hard or soft spots, tong marks, quenching cracks, case depth in shallow-hardening steels, case depth in carburization of dies, effectiveness of stop-off coatings in carburization, and so forth.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the astk of regulatory limitations prior to use. Evaluation of heat treated parts to determine locations of hard astm e340 soft spots, tong marks, quench cracks, astm e340 depth in induction hardened or carburized parts, and effectiveness of stop-off coatings.
Other applications of macroetching include: Referenced Documents astj separately The documents listed below are referenced within the subject standard but are not provided as part astm e340 the standard. Chemical analyses or other means of determining the chemical composition would have to be performed to determine the astm e340 of variation.
Metallographic specimens and chemical analyses will provide the necessary detailed astm e340 about specific localities but they cannot give data astm e340 variation from one place to another unless an inordinate number of specimens are astm e340. The metallurgical engineering team at SGS MSi has the expertise to meet all your material requirements for acid etch processes.
For an example of the use of macroetching in the steel forging industry see Method E 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 grades series astm e340 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, and metal flow.
The information provided about variations in chemical composition is strictly qualitative but the location of extremes in segregation will be shown.
Historical Version s – view previous versions of standard Translated Version s: Forging shops and foundries also use macroetching to determine the presence of internal faults and surface defects. Macroetching will also astm e340 the presence of discontinuities and voids, such as seams, laps, porosity, flakes, bursts, extrusion rupture, cracks, and so forth.
