A594

Scope

ASTM F594 covers the chemical and mechanical requirements for stainless steel nuts in diameters ranging from 1/4″ to 1-1/2″ inclusive and for use with fasteners conforming to ASTM F593. These nuts are for general purpose usage, and are available in seven alloy groups. Below is a basic summary of the common grades within the ASTM F594 specification. A number of other less common grades of ASTM F594 exist, but are not detailed in the description below. The Mechanical table here is limited to Alloy groups 1 and 2, as those are the most common and the Chemical table is only showing the most common alloy grades used for their respective alloy groups. More detailed information can be found in the ASTM F594 standard on the ASTM website.
