Find the optimal grade for your fastener application
By comparing the properties of different grades, such as mechanical strength, corrosion resistance, magnetic permeability, temperature resistance and fatigue strength, you can quickly identify the best BUMAX grades for your particular application. The tool allows you to compare up to three different grades at once.

Competitor Cross-Reference
| Standard Grade | BUMAX Equivalent | Why BUMAX is Better |
|---|---|---|
| A2-70 (304) | BUMAX 88 | Higher Mo (2.7 vs 0%), better corrosion, higher yield (640 vs 450 MPa) |
| A4-80 (316) | BUMAX 88 / 109 | Higher Mo (2.7 vs 2.0%), tighter tolerances, full traceability |
| Duplex 2205 | DX 129 | Higher strength (1200 vs 620 MPa TS), same corrosion resistance |
| Super Duplex 2507 | SDX 109 | Same corrosion (PRE 42), better mechanical properties |
| 12.9 Carbon Steel | ULTRA 159 / DX 129 | Corrosion resistant, no coating needed, higher ductility |
| Alloy 718 | HE | Cost-effective alternative for high-temp, similar performance to 700°C |
| 6Mo (254 SMO) | SA | PRE 43, same base material, fastener-optimized |
