The metallurgical engineering team at SGS MSi has the expertise to meet all your material requirements for acid etch processes. Examination and rating astm e381 specimens shall be in accordance with Sections 10 and 11 of this E standard.
It is the responsibility of the user of this astm e381 to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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 astm e381 showing the incidence of certain conditions such as: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are astm e381 provided as part of the standard.
The method employs the action of an acid or other corrosive agent to develop the astm e381 characteristics of a suitably prepared specimen. Click here to request a quote.
ASTM E – 17 Standard Method of Macroetch Testing Steel Bars, Billets, Blooms, and Forgings
Historical Version s – view previous versions of standard. Other applications of macroetching include: Astm e381 cast steel blooms and billets, in the as cast condition, shall astm e381 examined according to the procedures described in Sections 10 and Evaluation of heat treated parts to determine locations of hard or soft spots, tong marks, quench cracks, e81 depth in induction hardened astm e381 carburized parts, and effectiveness of stop-off coatings.
Establishment of general standards for acceptance or rejection for all conditions is impractical as some conditions must be considered relative to the part in which it occurs.
