What is 2205 stainless steel angle?
2205 stainless steel angle bar is a structural long steel product,specifically a duplex (austenitic-ferritic) stainless steel,composed of 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen. Its primary forms include equal-leg and unequal-leg angles. This material combines high strength (possessing a yield strength approximately double that of 316L) with excellent resistance to chloride stress corrosion cracking, pitting, and crevice corrosion; it is commonly utilized in oil and gas equipment, paper-making machinery, environmental protection systems, and high-strength structural components.
2205 Stainless Steel Angle Supplier
GNEE is a professional duplex stainless steel manufacturer with over 20 years of experience, dedicated to exporting Alloy 2205 (UNS S32205 / 1.4462) duplex stainless steel angle bars to more than 70 countries worldwide. We have supplied identical specifications for Middle East desalination plants and offshore oil platforms, with products verified by third-party inspections such as SGS, BV, and ABS classification society certification.
EN 10204 3.1 Mill Test Certificate (MTC)
The pitting and crack corrosion resistance of GNEE 2205 equal angles is 3–5 times higher than that of 316L stainless steel, making it especially suitable for chloride-containing environments and effectively extending service life by up to twice as long. The yield strength of 2205 stainless steel angle bar is ≥450 MPa (approximately twice that of 316L), with a tensile strength ≥620 MPa, hardness ≤290 HBW, and impact toughness ≥40J at -40°C. Using this material allows for a 20%–30% reduction in structural weight while maintaining performance.
Our 2205 angle bar specifications range from 20×20×3 mm to 200×200×20 mm, available in both equal and unequal angles. Surface finishes include hot-rolled and pickled options. We also provide customized sizes, cutting, drilling, drawing-based fabrication, and small-batch sample services, including precision cutting according to engineering drawings.

What are the common applications for 2205 angles?
Brackets for offshore oil platforms.
Supports in chemical processing tanks.
Structural components for desalination plants.
Bridges and harbor infrastructure in coastal areas.
As 2205 is a specialized stainless steel grade, many smaller traders do not maintain stock on hand. Gnee, however, typically maintains a substantial inventory, enabling rapid delivery and helping to shorten project timelines.
Gnee maintains long-term strategic partnerships with leading global steel manufacturers-such as TISCO, Baosteel, and Tsingshan-thereby guaranteeing the authenticity of our raw materials. Given that 2205 is a specialized stainless steel, custom production cycles can take as long as 45 to 60 days; however, Gnee typically keeps a large stock readily available, facilitating rapid delivery and effectively reducing project durations.
