Duplex Alloy Plate
We supply duplex alloy plates, a family of stainless steels engineered with a mixed microstructure of austenite and ferrite, delivering a superior combination of high strength and excellent corrosion resistance. Designed to withstand demanding environments, duplex plates offer enhanced performance over standard austenitic grades while maintaining cost-effectiveness compared to high-nickel alloys.

Product Description

合金类 拷贝


  • High Strength & Lightweight: Yield strength approximately double that of standard austenitic stainless steels (e.g., 304/316), enabling lighter and more durable designs.

  • Excellent Corrosion Resistance: Outstanding resistance to chloride stress corrosion cracking, pitting, and crevice corrosion, particularly in marine and chemical environments.

  • Grade Versatility: Available in standard duplex (e.g., 2205/UNS S32205), super duplex (e.g., 2507/UNS S32750), and lean duplex grades for varying performance requirements.

  • Cost-Efficient Durability: Extended service life and reduced maintenance needs offer lower lifecycle costs in harsh operating conditions.

Duplex plates are widely used in offshore and marine structures, chemical processing equipment, oil and gas pipelines, desalination plants, and pulp and paper machinery. We provide precision cutting, forming support, and full material certification tailored to your project specifications.
