ASTM F593
Scope
ASTM F593 covers the chemical and mechanical requirements for stainless steel bolts, hex cap screws and studs in diameters ranging from 1/4″ to 1-1/2″ inclusive. These fasteners are for general purpose usage, and are available in seven alloy groups. Below is a basic summary of the common grades within the ASTM F593 specification. A number of other less common grades of ASTM F593 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 F593 standard on the ASTM website.
F593 Alloy Groups
Alloy Group | Alloy Designation | Alloy Type |
---|---|---|
1 | 303, 304, 304L, 305, 384, XM1, 18-9LW, 302HQ, 303Se | Austenitic |
2 | 316, 316L | Austenitic |
3 | 321, 347 | Austenitic |
4 | 430, 430F | Ferritic |
5 | 410, 416, 416Se | Martensitic |
6 | 431 | Martensitic |
7 | 630 (17-4) | Precipitation Hardening |
*The selection of an alloy within each group is at the discretion of the manufacturer unless the purchaser requests a specific alloy. |
