What is EN 1.4462 square tubing?
EN 1.4462 square tubing is a super duplex stainless steel with a microstructure of approximately 50% ferrite and 50% austenite. It is produced using hot forming or seamless rolling processes with strict tolerances, making it suitable for structural and pressure-bearing applications. EN 1.4462 stainless steel has a high yield strength (approximately 550 MPa), almost twice that of 304L stainless steel, and exhibits good weldability and dimensional stability.

Why is EN 1.4462 square tubing more expensive than 2205 square tubing?
Due to its higher alloy content (Cr, Mo, N) and solution annealing treatment, it offers superior corrosion resistance and strength.
Can EN 1.4462 square tubing be welded?
Yes. With the appropriate welding materials and processes, EN 1.4462 square tubing provides excellent weld strength and corrosion resistance.
What sizes of EN 1.4462 square tubing are available?
Square tubing sizes range from 20×20 mm to 200×200 mm, with wall thicknesses from 2 mm to 20 mm, and custom lengths are available upon request.
2205 vs. 316L Stainless Steel: Cost
Compared to 316L stainless steel square tubing (US$3.2-4.0/kg), the price premium of 2205 stainless steel stems from its 21.0-23.0% chromium content, 2.5-3.5% molybdenum content (PREN 32-36), and twice the yield strength (≥450 MPa) in harsh chloride-rich environments.
GNEE provides factory inspection certificates (MTC) with complete chemical/mechanical performance data, and third-party certification services (SGS, BV, TUV) are available. Products are packaged with standard export packaging (anti-rust oil + waterproof paper + PVC film + steel strapping + wooden pallets). The minimum order quantity (MOQ) is 1 ton, and the delivery time for stock orders is 7-15 days.
