Stainless Steel Angle - 304/316 Grade, Equal/Unequal Leg, Custom Cut to Size

Technical Specifications of Stainless Steel Angle

Stainless Steel Angle - 304/316 Grade, Equal/Unequal Leg, Custom Cut to Size

Stainless Steel Angle is a structural L-shaped bar widely employed in architectural frameworks, industrial equipment, marine installations, and food processing facilities—where superior corrosion resistance, high strength, and long-term dimensional stability are non-negotiable. Engineered from premium-grade 304 and 316 stainless steel, our angles deliver mill-direct rates without compromising on ASTM A276/A484 compliance, precise tolerances, or traceable material certification. Designed for engineers, fabricators, and procurement specialists seeking reliable supply chain continuity and certified performance across demanding environments.

What is Stainless Steel Angle?

Stainless Steel Angle is a hot-rolled or cold-finished structural profile with two perpendicular legs forming an “L” cross-section. It is manufactured in both equal-leg (e.g., 50×50×6 mm) and unequal-leg configurations (e.g., 75×50×5 mm), enabling optimized load distribution and space-efficient mounting. Unlike carbon steel angles, stainless variants maintain exceptional mechanical integrity in chloride-rich, acidic, or high-humidity conditions due to chromium (≥18.0%) and nickel (8.0–10.5% for 304; 10.0–14.0% for 316) content—plus molybdenum (2.0–3.0%) in 316 grades for enhanced pitting resistance per ASTM A240/A240M-20a Section 6.2.

Stainless Steel Angle Technical Specifications

Our Stainless Steel Angle complies with ASTM A276/A484 for chemical composition and mechanical properties, EN 10088-2:2014 for dimensional accuracy, and ISO 9001-certified production controls. Standard grades include 304 (UNS S30400) with tensile strength of 515 MPa minimum and yield strength of 205 MPa minimum, and 316 (UNS S31600) delivering 515 MPa tensile strength and 210 MPa yield strength—both featuring elongation ≥40% in 50 mm. Leg thickness ranges from 3 mm to 16 mm; standard lengths span 6 m, 6.1 m, and 12 m, with custom cut-to-size options available down to ±0.5 mm tolerance. Surface finishes include 2B (mill-annealed), BA (bright annealed), and No. 4 brushed per ASTM A480/A480M.

Why Choose Our Stainless Steel Angle?

We specialize in precision-engineered Stainless Steel Angle backed by over 18 years of B2B supply experience across 32 countries—including turnkey projects for offshore platforms in the North Sea and cleanroom infrastructure in Singapore pharmaceutical plants. Every batch undergoes 100% ultrasonic testing and is supplied with EN 10204 3.1 material test certificates verifying chemical analysis (ICP-OES), mechanical test results (tensile/yield/elongation), and intergranular corrosion resistance per ASTM A262 Practice E. Our inventory includes hot-rolled equal-leg angles (25×25×3 mm to 150×150×12 mm) and cold-drawn unequal-leg variants (40×25×3 mm to 120×80×10 mm)—all traceable to heat number and fully compliant with RoHS and REACH directives.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

The MOQ for standard Stainless Steel Angle sizes is 500 kg per grade and dimension. For custom-cut or non-stock items, MOQ starts at 1 metric ton—with no penalty for mixed-specification orders shipped on consolidated pallets.

Do you provide material test certificates?

Yes—we issue EN 10204 3.1 Material Test Certificates with every shipment. These documents confirm full compliance with ASTM A276/A484, including certified chemical composition (C ≤0.08% for 304, ≤0.03% for 316L), tensile properties, hardness (≤201 HB for 304, ≤217 HB for 316), and microstructure verification.

What is the typical delivery time?

In-stock Stainless Steel Angle items ship within 3–5 business days. Custom-cut or hot-rolled orders require 12–18 days from confirmation, supported by real-time production tracking and weekly logistics updates via our ERP-integrated portal.

Can you cut to custom sizes?

Absolutely. We offer precision saw-cutting, plasma profiling, and CNC bending services for Stainless Steel Angle—down to ±0.3 mm linear tolerance and ±1.0° angular accuracy. Common requests include notched ends, pre-drilled holes (ISO 273 standard), and radius-formed corners per customer drawings.

Which grade is better for coastal applications?

For marine or high-chloride environments, 316 stainless steel angle is the preferred choice due to its 2.0–3.0% molybdenum content, which significantly improves resistance to pitting and crevice corrosion compared to 304. Independent salt-spray testing per ASTM B117 confirms 316 angles withstand >1,500 hours before red rust formation—versus ~500 hours for 304 under identical conditions.

Are unequal-leg angles available in 316L?

Yes. We routinely supply 316L unequal-leg Stainless Steel Angle in dimensions such as 80×50×5 mm, 100×65×6 mm, and 120×80×8 mm—manufactured to ASTM A276 with low-carbon chemistry (C ≤0.03%) to prevent sensitization during welding and ensure optimal intergranular corrosion resistance per ASTM A262 Practice A.
