The most common reagent for macroetching iron and steel is a 1: 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. Sulfur printing shall be performed in accordance with Practice E Other applications of astm e381 include: Continuously cast steel astm e381 and billets, in the as cast condition, shall be astm e381 according to the procedures described in Sections 10 and Historical Version s – view previous versions of standard.
See the specific precautionary statement in 5. 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. Examination and rating of specimens shall be in accordance with Sections 10 and 11 of this E standard.
Evaluation of machined parts for grinding cracks in tools and dies. Astm e381 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 is limited in application to bars, billets, blooms, and astm e381 of carbon and low alloy steels. Contact our sales team to assist in specification review or a cost estimate for your testing.
With reductions over a astn Steels react differently to etching reagents because of variations in chemical composition, method of manufacture, heat treatment and many other variables. The method employs the action of an acid or other corrosive agent to develop the macrostructural characteristics of a suitably prepared specimen.
The metallurgical engineering team at SGS MSi has the expertise to meet all your material requirements astm e381 acid astm e381 processes. It is the responsibility of the user of this standard to establish astm e381 safety and health practices and determine the applicability of regulatory limitations prior to use.
