Product Description

合金类 拷贝



  • High Strength & Lightweight: Approximately double the yield strength of standard austenitic grades (e.g., 304/316), enabling lighter and more durable designs.

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

  • Grade Flexibility: Available in standard duplex (e.g., 2205/UNS S32205), super duplex (e.g., 2507/UNS S32750), and lean duplex grades to meet varying mechanical and environmental requirements.

  • Comprehensive Compliance: Manufactured to ASTM, ASME, EN, and other international standards, offered in seamless and welded forms.

Ideal for offshore and marine structures, chemical processing plants, oil and gas pipelines, desalination systems, and heat exchangers. We provide customized cutting, bending, welding support, and full traceable certification to meet your project's technical and quality demands.
