Known for their commitment to quality, they consistently deliver products that adhere to strict international standards, ensuring exceptional strength, corrosion resistance, and durability. With cutting-edge manufacturing facilities and a dedicated team of skilled professionals, Phehlukwayo Metal tailors their Duplex Steel Bars and Rods for a variety of industries, including oil and gas, chemical processing, marine, and construction. Their unwavering focus on quality, precision, and customer satisfaction has made them a go-to partner in both local and global markets.
Duplex Steel Bars and Rods are made up of about 22–25% chromium, 4–7% nickel, along with small amounts of molybdenum, nitrogen, and manganese. This unique dual-phase microstructure, which includes both austenitic and ferritic phases, gives these steels remarkable strength and corrosion resistance. They boast high tensile and yield strength, outstanding toughness, and excellent resistance to stress corrosion cracking, pitting, and crevice corrosion. Even in harsh environments, they maintain stability, offering great weldability, formability, and long-lasting performance, even under extreme temperatures and pressures.
