🔍 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.
