Understanding ASTM A895: The Standard for Free-Machining Stainless Steel

This paper examines ASTM A895, a standard specification that governs the application and performance of chemical-resistant, low-build, baking-type coatings on steel fasteners and hardware. Unlike heavy-duty barrier coatings, these low-build films provide corrosion protection while maintaining critical dimensional tolerances. The paper details the chemical composition requirements, coating thickness parameters (typically 0.0002 to 0.0008 inches), adhesion testing, and corrosion resistance criteria. Applications in automotive, electronics, and precision instrumentation are analyzed, along with comparative performance against zinc plating and organic dip coatings. astm a895
