Technical Performance & Features
Tensile & Bend Strength
Our stainless steel angle ASTM A276 products are engineered to withstand extreme mechanical stress. For instance, AISI 304L angles achieve tensile strengths of 515–720 MPa, ideal for stainless steel angle steel frameworks in construction. The high nickel content in AISI 316L enhances ductility (40–50% elongation), allowing seamless bending for custom stainless steel angle trim designs without cracking.
Weight Calculation
Calculate the weight of a stainless steel angle ASTM A276 using:
Weight (kg/m) = (Side1 + Side2 – Thickness) × Thickness × 0.00793
For a 50x50x5mm angle:
Weight = (50 + 50 – 5) × 5 × 0.00793 = 3.77 kg/m
Why Stainless Steel Angles Rust
Even premium grades like AISI 316L can corrode under specific conditions:
- Intergranular Corrosion: Poor welding practices or prolonged exposure to 450–850°C temperatures degrade chromium-carbide boundaries.
- Pitting in Chlorides: Saltwater or bleach splashes penetrate passive layers, causing localized pits.
- Galvanic Coupling: Direct contact with carbon steel or copper accelerates oxidation.
Our angles undergo solution annealing (AISI 304/316L) and electropolishing to minimize these risks, validated by ASTM A262 Practice E testing.
Identification & Marking
Each stainless steel angle ASTM A276 is stamped with:
- Grade (e.g., 304L, 316L)
- Heat Number (for traceability)
- ASTM A276 Compliance Mark
QR codes link to TISCO mill test certificates, including chemical composition and mechanical test results.
