Phehlukwayo Metal is a reputable manufacturer and supplier located in Cape Town, South Africa, known for its top-notch stainless steel products. One of the standout items in their extensive lineup is the Stainless Steel 321H Hex Bar/Rod, celebrated for its outstanding performance and reliability. Crafted with precision and in line with international standards, these bars and rods boast superior strength, excellent corrosion resistance, and remarkable durability, making them perfect for demanding industrial applications. Phehlukwayo Metal’s dedication to quality ensures that every Stainless Steel 321H Hex Bar/Rod meets the highest standards for both local and global markets.
The Stainless Steel 321H Hex Bar/Rod is an austenitic stainless steel alloy that includes chromium (17–19%), nickel (9–12%), and titanium, which enhances its stability against intergranular corrosion. With a higher carbon content compared to the standard 321, the 321H grade provides improved high-temperature strength and creep resistance. It has a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of 40%. This unique composition guarantees excellent oxidation resistance, toughness, and long-lasting performance in high-temperature settings and challenging operating conditions.

SS 321H Hex Bars/Rods are highly resistant to oxidation and intergranular corrosion due to titanium stabilization, making them ideal for high-temperature environments. They offer excellent strength, durability, and resistance to sulfur compounds, ensuring reliability in extreme conditions.
SS 321H Hex Bars/Rods are commonly used in aerospace, chemical processing, power generation, petrochemical, and pharmaceutical industries. They are ideal for high-temperature applications such as heat exchangers, pressure vessels, exhaust systems, and furnace components due to their excellent corrosion resistance.
SS 321H Hex Bars/Rods can be welded easily, thanks to their titanium stabilization, which prevents sensitization and intergranular corrosion. However, it's essential to use low-carbon filler materials to maintain the material's properties and prevent carbide precipitation. Pre-heating and post-weld heat treatment may be required for optimal results.
The Stainless Steel 321H Hex Bar/Rod from Phehlukwayo Metal is widely utilized in industries that demand exceptional heat resistance and mechanical strength. Typical applications include exhaust systems, heat exchangers, furnace components, jet engine parts, and chemical processing equipment. Its stability and resistance to scaling make it particularly suitable for continuous high-temperature environments. Additionally, the alloy’s durability and corrosion resistance render it ideal for pressure vessels, refinery equipment, and structural applications in both marine and aerospace sectors. Phehlukwayo Metal is committed to maintaining consistent quality, making these hex bars and rods a go-to choice for critical industrial operations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
