Description

ASTM A561-71-Reapproved1999

Historical Standard: Standard Recommended Practice for Macrotech Testing of Tool Steel Bars

ASTM A561

Scope

1.1 This recommended practice for macroetch testing has been found to be a useful and reliable method for evaluating the quality of tool steel bars. It is used as a quality control and inspection test to reveal by deep acid etching the macrostructure in specimens cut from bars and to show the presence of such conditions as pipe, cracks, porosity, segregation, or foreign material. The etched surface is generally examined visually, but magnification up to about 10X is occasionally employed.
