10+4mm 2205 Duplex Stainless Clad Plate Metallurgical Bond High Mechanical Stability
Product Description
2205 duplex stainless steel clad plate is a high-strength and anti-corrosion composite material, adopting 10mm thick high-strength carbon steel base layer and 4mm 2205 duplex stainless steel cladding layer, formed by integral metallurgical bonding process. Different from ordinary austenitic stainless steel, 2205 duplex steel has dual-phase structure of ferrite and austenite, balancing high strength and excellent corrosion resistance. The product is produced through precise hot rolling and high-temperature annealing process, realizing tight combination of two layers of metal, with no gaps or impurities in the bonding interface, and stable overall mechanical structure.
This product has four prominent core advantages with accurate data support. Firstly, ultra-high mechanical strength, the overall yield strength reaches ≥450MPa, 1.5 times higher than ordinary 304 composite plates, suitable for heavy-load bearing equipment. Secondly, superior stress corrosion resistance, effectively resisting sulfide and chloride stress corrosion, solving cracking problems of ordinary stainless steel plates in high-stress corrosive environment. Thirdly, reliable metallurgical bonding, the bonding interface realizes atomic fusion, with shear strength ≥300MPa, resistant to repeated bending and impact. Fourthly, stable structural performance, no structural fatigue or performance attenuation after long-term heavy-load operation, with service life increased by 40% compared with ordinary composite plates.
Relying on high strength and strong corrosion resistance, 2205 duplex stainless steel composite plates are widely used in heavy-duty and high-corrosion industrial fields. The main application scenarios include petrochemical reaction equipment, natural gas pipeline supporting facilities, high-pressure storage tanks, ocean platform auxiliary equipment, papermaking and pulp processing equipment, and chemical fertilizer production equipment. It provides high-stability material solutions for industrial equipment under long-term heavy-load and corrosive working conditions, reducing equipment failure rate and maintenance cost.

We implement strict full-link quality control. All raw materials are from domestic and international first-tier steel mills with complete chemical composition and mechanical property certificates. During production, numerical control equipment accurately controls rolling pressure and temperature to ensure uniform bonding. Finished products undergo ultrasonic full inspection, mechanical tensile and shear test, corrosion resistance sampling test and dimensional precision inspection. All products meet GB/T 8165 and ASTM A790 duplex steel standards, with complete quality inspection reports.
For packaging and delivery, products are treated with anti-rust treatment, wrapped with waterproof and anti-collision materials, and fixed with iron frame brackets to prevent deformation during long-distance transportation. Standard 10+4mm specifications are in stock with 5-7 days delivery. Customized sizes take 10-15 working days. We support diversified international logistics schemes to ensure safe and intact delivery of products to global industrial customers.
