Astm A895

is a specialized technical standard developed by ASTM International that establishes the requirements for free-machining stainless steel in the forms of plate, sheet, and strip. This specification is critical for manufacturers who require corrosion-resistant materials that can also be efficiently processed using high-speed automated machining tools. Scope and Application

The primary purpose of is to define the chemical composition and mechanical properties of stainless steel grades designed for improved machinability. Unlike standard stainless steel, which can be difficult to machine due to its toughness and tendency to work-harden, free-machining grades specified under this standard are alloyed with elements that act as "chip breakers."

ASTM A895 specifically applies to:

Per ASTM A895, sampling plans follow ANSI/ASQ Z1.4 (formerly MIL-STD-105E):

Fasteners and small hardware components require corrosion protection that does not alter thread pitch, head geometry, or fit tolerances. Traditional galvanizing or powder coating often adds excessive thickness (0.002–0.005 inches), leading to assembly failures. ASTM A895 addresses this gap by standardizing low-build coatings (≤0.001 inches) that are baked (thermoset) for chemical resistance. The standard covers both application methods (dip-spin, spray, or dip-drain) and performance validation.

While ASTM A895 is the specification , it covers several specific grades (often recognizable by their Type numbers): is a specialized technical standard developed by ASTM
