ASTM A593 Bolts

ASTM F593 is the standard specification covering the chemical and mechanical requirements for stainless steel bolts, hex cap screws, and studs with diameters ranging from 1/4″ to 1-1/2″. These fasteners are intended for general-purpose applications where good corrosion resistance is the primary requirement.

Compared to specified high-temperature or high-strength specifications, ASTM F593 provides a reliable, well-organized base specification for everyday stainless steel bolting. It organizes different stainless steel alloys into seven groups, or “Alloy Groups” and specifies different strength levels, or “Conditions”, that can be developed through cold working. This makes F593 Bolts a versatile and dependable choice for a vast range of industrial, commercial, and municipal applications.

The standard classifies stainless steel alloys into seven groups based on chemical family and properties. Of these, the most common groups include:

• Alloy Group 1: Group 1 contains the most commonly used austenitic stainless steels, like ASTM F593 type 304 (18-8) and 304L. These materials have excellent corrosion resistance in most general atmospheric and freshwater environments.
• Alloy Group 2: This group is also austenitic and includes ASTM F593 type 316 and 316L. These materials have molybdenum added which provides better overall corrosion resistance with a specific emphasis on chlorides. Thus, making these an ideal choice for marine, coastal and chemical processing environments.
• Other Groups: The specification also covers other, less common Ferritic (Group 4), Martensitic (Groups 5 & 6) and Precipitation-Hardening (Group 7) stainless steels for more specific applications.
