Material Overview
CD4MCU is a high-performance duplex (ferritic-austenitic) stainless steel round bar offering exceptional corrosion resistance, high strength, and excellent wear resistance. Its unique composition makes it ideal for harsh environments including seawater, chemical processing, and oil & gas applications.
Key Features & Benefits
Superior corrosion resistance against pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments
High strength and toughness with nearly double the yield strength of standard 300-series stainless steels
Excellent wear and erosion resistance for abrasive and high-flow conditions
Good weldability and fabrication properties with controlled welding techniques
Cost-effective solution with longer service life reducing maintenance and replacement costs
