Key Performance Properties
Tensile Strength
Stainless steel angle iron grades like 304 and 316L exhibit tensile strengths of **≥520 MPa** and **≥485 MPa**, respectively, ensuring structural integrity in load-bearing applications such as industrial shelving and bridge supports. Duplex 2205 angles combine austenitic and ferritic phases, achieving **≥620 MPa tensile strength**, ideal for offshore platforms exposed to chloride-rich environments.
Bend Strength
Cold-rolled stainless steel angle trim products demonstrate superior bend resistance due to work hardening. For example, hot-rolled 304 angles achieve **≥205 MPa yield strength**, while cold-drawn variants reach **≥350 MPa**, suitable for seismic-resistant architectural frameworks.
Identification & Marking
Each stainless steel angle brackets is laser-etched with:
- Material Grade (e.g., SUS316L)
- Standard Code (e.g., ASTM A554)
- Heat Number for traceability
- Dimensions (L×W×Thickness)
Custom QR codes or client-specific logos are available for bulk orders.

Why Stainless Steel Angles May Rust?
Despite corrosion resistance, rust occurs under specific conditions:
- Chloride Exposure: Coastal environments or de-icing salts degrade the chromium oxide layer, causing pitting.
- Mechanical Abrasion: Scratches from improper handling or welding tools create galvanic corrosion sites.
- Low Oxygen Environments: Stagnant water or crevices accelerate localized corrosion in 304-grade angles.
- Iron Contamination: Residual iron particles from carbon steel tools trigger electrochemical reactions.
Preventive Measures:
- Select stainless steel angle brackets with 316L (2.5% Mo) for marine/chemical exposure.
- Passivate welded joints to restore chromium oxide layers post-fabrication.
- Use pH-neutral cleaners (6–8) to avoid surface degradation.
