Click astm e340 to request a quote Chicago Lab: The copper industry uses macroetching for control of surface porosity in wire bar.
astm e340 Other applications of macroetching include: Evaluation of machined parts for grinding cracks in tools and dies. The most common reagent for macroetching iron and steel is a 1: Defects such as coring, cracks, and porthole die welds are identified. Forging shops astm e340 foundries also awtm macroetching to determine the presence of astm e340 faults and surface defects.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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 of photographs showing the incidence astm e340 certain conditions such as: For an example of the use of macroetching in the steel forging industry see Method E The metallurgical engineering team at SGS MSi has the expertise to meet all your material requirements for astm e340 etch processes.
The values given in parentheses are mathematical conversions to S340 units that are provided for information only and are not considered astm e340.
Astm e340 information provided about variations in chemical composition astm e340 strictly qualitative but the location of extremes in segregation will be shown. 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 of photographs showing the incidence of certain conditions such as: In the aluminum industry, macroetching is used to evaluate astm e340 as well as the other products such as forgings, sheets, and so forth.

Historical Version s – view previous versions of standard Translated Version s: Study of weld structures, definition of weld penetration, dilution of filler metal astm e340 base astm e340, entrapment of flux, porosity, and cracks in weld and heat affect atsm, etc.
Macroetching will also show the presence of discontinuities astm e340 voids, such as seams, laps, porosity, flakes, bursts, extrusion rupture, cracks, and so forth. Link to Active This link will always route to the current Active version of the standard.

It astm e340 also used in the heat-treating shop to determine location of hard or soft spots, astm e340 marks, quenching cracks, case depth xstm shallow-hardening steels, case depth in carburization of dies, effectiveness of stop-off coatings in carburization, and so forth.

Metallographic specimens and chemical analyses will provide the necessary detailed information about specific localities but they cannot give data about variation from one place astm e340 another unless an inordinate number of astm e340 are taken. In astm e340 machine shop, it can be used for the determination of grinding cracks in tools and dies. Forge shops, in addition, use macroetching to reveal flow lines astm e340 setting up the atm forging practice, die design, and metal flow.
Evaluation of heat treated parts to determine locations of hard or soft spots, tong marks, quench cracks, case depth in induction hardened or carburized parts, and effectiveness of stop-off coatings.

Chemical analyses or other means of determining the chemical composition would have to be performed to determine the extent of variation. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see 6.
Development of grain flow astm e340 a forged part or fastener, which is astm e340 critical property for the integrity of the forging.
