Situated in the heart of Amman, Jordan, Sabra Metals has built a strong reputation as a dedicated manufacturer and supplier of high-performance metals. Our focus is on providing robust and reliable materials engineered to meet the demanding needs of modern industry. Among our key offerings is the Duplex Steel Hollow Bar, a product that perfectly embodies our commitment to quality and durability. This material is specifically chosen for environments where exceptional strength and corrosion resistance are not just beneficial, but absolutely essential for long-term success and safety.
The strength of our Duplex Steel Hollow Bar comes from its unique composition, which creates a balanced microstructure of austenite and ferrite phases. This blend grants it an impressive combination of high tensile and yield strength, far exceeding that of standard stainless steels. It also possesses excellent toughness and a remarkable resistance to stress corrosion cracking. Essentially, this means the bar is built to handle heavy loads and aggressive, corrosive environments without compromising its structural integrity, offering a reliable solution where other materials might fail.
