astm-a322Grades that cite ASTM A322
The grades in our database whose sources name ASTM A322. Each row shows how the source prints it, the product form the source ties to it where it says so, and the strength we hold for the grade. This is a finding aid, not the standard: the current text of ASTM A322 is sold by its publisher.
| Grade | As printed | Yield strength | Tensile strength |
|---|---|---|---|
| Alloy steel AISI 4130 | A322 | 435 to 1,330 MPa | 655 to 1,600 MPa |
| Alloy steel AISI 4140 | A322 | 570 to 1,235 MPa | 745 to 1,283 MPa |
| Alloy steel AISI 4340 | A322 | at least 665 MPa | 745 to 1,550 MPa |
Ranges run across the tempers and conditions each source reports, so a heat-treatable grade shows a wide range. Open a grade for each value with its condition and source.
