Based in Amman, Jordan, Sabra Metals is a reliable manufacturer and supplier known for its top-notch Stainless Steel 347H Forgings, designed for high-temperature and pressure-critical applications. These forgings are crafted from niobium-stabilized austenitic stainless steel with a higher carbon content, ensuring they deliver exceptional strength and outstanding resistance to intergranular corrosion, even at elevated temperatures. Sabra Metals maintains strict oversight of its forging processes, chemical makeup, and dimensional precision to comply with international standards. With state-of-the-art manufacturing facilities and thorough inspection protocols, the company caters to industries like petrochemical, power generation, oil and gas, and heavy engineering around the globe.
Stainless Steel 347H Forgings are composed of chromium (17–19%), nickel (9–13%), niobium stabilization, and a higher carbon content that boosts high-temperature strength. This unique blend helps prevent carbide precipitation and enhances creep resistance during extended heat exposure. On the mechanical side, SS 347H boasts higher tensile strength, impressive toughness, and robust resistance to thermal fatigue. The forging process refines the grain structure, leading to better pressure resistance, structural integrity, and long-lasting mechanical stability, even under extreme thermal and mechanical conditions.
