🔍 Material Overview: SUS303 Stainless Steel
This muzzle brake is manufactured from SUS303 (equivalent to AISI 303), an austenitic stainless steel known for its ease of machining and corrosion resistance.
| Property | Description |
|---|---|
| Composition | Fe, 17–19% Cr, 8–10% Ni, ~0.15% S, ~1% Mn |
| Machinability | Excellent (better than SUS304) |
| Corrosion Resistance | Good, slightly lower than SUS304 |
| Tensile Strength | Moderate (500–750 MPa) |
| Weldability | Poor (due to sulfur content) |
| Magnetism | Non-magnetic (annealed condition) |
SUS303 is a good choice for civilian semi-automatic rifles and moderate use, but it is not intended for extreme military-grade abuse.
