Phehlukwayo Metal, a well-respected manufacturer and supplier located in Cape Town, South Africa, specializes in top-notch Stainless Steel 347H Forgings that are crafted for outstanding performance in high-temperature and corrosive settings. By leveraging cutting-edge forging technology and high-quality raw materials, the company guarantees that every product adheres to international standards for strength and durability. Known for their remarkable resistance to oxidation, intergranular corrosion, and creep stress, Stainless Steel 347H Forgings from Phehlukwayo Metal are perfect for critical industrial applications. Their dedication to precision engineering and quality assurance means you can count on these stainless steel solutions to last.
These forgings are primarily made of iron, featuring 17–19% chromium, 9–13% nickel, along with small amounts of niobium and tantalum to prevent carbide precipitation. The increased carbon content in the “H” grade boosts creep strength and heat resistance. With a tensile strength of about 515 MPa and a yield strength of around 205 MPa, they also exhibit excellent toughness at elevated temperatures. Their exceptional resistance to scaling and mechanical stability under thermal stress make them ideal for high-temperature service environments.

Yes, Stainless Steel 347H forgings can be used for potable water applications, offering excellent corrosion resistance and durability, particularly in high-temperature systems or environments with varying water quality.
Yes, Stainless Steel 347H forgings are highly suitable for high-temperature applications due to their niobium stabilization, which enhances resistance to oxidation, thermal stress, and intergranular corrosion at elevated temperatures.
Stainless Steel 347H Forgings find extensive use in sectors like chemical processing, power generation, refineries, and aerospace, thanks to their impressive heat and corrosion resistance. They are perfect for creating furnace parts, pressure vessels, boiler tubes, heat exchangers, and exhaust systems that face high temperatures and harsh chemicals. Their ability to maintain mechanical integrity under prolonged thermal stress makes them suitable for continuous operation in oxidation-prone and carburizing conditions. For demanding applications that require reliability and a long service life, Stainless Steel 347H Forgings are the go-to choice.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
