Performance Attributes
Tensile & Bending Strength
Our stainless steel angle iron in 304 grade offers a tensile strength range of 515–620 MPa, making it ideal for structural frameworks requiring corrosion resistance and moderate load-bearing capacity, such as stainless steel angle brackets in coastal architecture. The 316L grade excels in high-stress environments (520–690 MPa tensile strength), perfect for marine engineering or chemical plants where chloride resistance is critical. For cost-effective solutions, 430 stainless steel (450–600 MPa) balances strength and affordability in indoor applications like HVAC systems.
Identification & Traceability
Each stainless steel 2 inch angle iron near me is laser-etched with a unique identifier (e.g., "316L-2"x2"x1/4"") that includes grade, dimensions, and batch number. This ensures compliance with ASTM/EN standards and simplifies inventory management for contractors.
Weight Calculation
Calculate the weight of a stainless steel angle iron using:
- 304/316L: Density = 8.0 g/cm³ → A 2"x2"x1/4" angle weighs 6.25 lbs/ft.
- 430: Density = 7.7 g/cm³ → A 2"x2"x1/4" angle weighs 5.98 lbs/ft.
Why Stainless Steel Can Rust
Despite its corrosion resistance, stainless steel angle iron may rust under specific conditions:
- Chloride Exposure: Prolonged contact with seawater or road salts can degrade the passive chromium oxide layer, particularly in 430 grade (lower nickel content).
- Galvanic Corrosion: Direct contact with carbon steel or copper in humid environments accelerates oxidation. Use insulating materials like nylon washers for stainless steel angle brackets in mixed-metal assemblies.
- Surface Contamination: Iron particles from cutting tools or grinding can embed into stainless steel, leading to localized rust. Passivation (nitric acid treatment) removes contaminants and restores corrosion resistance.
Manufacturing & Processing
- Cold Rolling & Forming: Precision cold rolling ensures ±0.005" thickness tolerance for stainless steel 2 inch angle iron near me, optimized for CNC machining and welding.
- Heat Treatment: 316L stainless steel undergoes solution annealing (1,900–2,050°F) to eliminate sensitization and enhance intergranular corrosion resistance.
- Surface Finishing: Electropolishing (for 316L grade) reduces surface roughness (Ra ≤0.4 μm), minimizing bacterial adhesion in food processing facilities.
Applications
- Marine Engineering: Stainless steel angle iron (316L grade) for boat frames and offshore platforms.
- Architectural Trim: Stainless steel angle brackets (304 grade) in high-humidity environments like swimming pools.
