With a strong focus on precision, durability, and ensuring customer satisfaction, Phehlukwayo Metal provides products that not only meet international standards but also excel in challenging environments. Our Stainless Steel 321 Round Bars and Rods are designed for outstanding strength, corrosion resistance, and heat tolerance, making them perfect for both industrial and commercial uses. By blending cutting-edge manufacturing techniques with skilled craftsmanship, Phehlukwayo Metal has established itself as a dependable partner for stainless steel solutions throughout South Africa.
Stainless Steel 321 Round Bars and Rods are titanium-stabilized austenitic stainless steels, typically composed of 17–19% chromium, 9–12% nickel, and a small amount of titanium (at least five times the carbon content). These components significantly improve resistance to intergranular corrosion and high-temperature oxidation. The alloy boasts impressive tensile strength (around 515 MPa), yield strength (205 MPa), and elongation (40%). With excellent toughness and stability at elevated temperatures up to 870°C, Stainless Steel 321 is perfectly suited for heat-exposed and corrosive settings.
