Duplex Steel S31803 Angle About

Duplex Steel S31803 Angle is a structural section material made from S31803 duplex stainless or 2205 stainless steel. This duplex alloy has a two-phase microstructure structure that combines both the austenitic and ferritic stainless steels and, therefore, has a high corrosion resistance and mechanical strength. Duplex Steel S31803 Angle is used in industries with high strength and corrosion resistance, like offshore, marine, chemical, and oil and gas industries.

Superior Corrosion and Stress Resistance

Duplex Steel S31803 Angle offers excellent resistance to stress corrosion cracking and pitting, thanks to its duplex structure and carefully balanced alloy content. This makes it a preferred choice for harsh environments such as marine, chemical, and oil & gas industries.

Versatile Dimensions and Tailored Finishes

Available in standard lengths (6 meters) and customizable sizes (20-150 mm width, 3-12 mm thickness), the angle bar caters to diverse project requirements. With options for bright, hot rolled, pickled, or brushed surfaces, it's easy to find the right fit for structural, support, or load-bearing needs.

Reliable Structural Performance

With a minimum yield strength of 450 MPa and elongation of at least 25%, Duplex Steel S31803 Angle maintains structural integrity under heavy loads. Its moderate machinability and good weldability allow for flexibility in fabrication, repair, and installation.
