Neith Metals, based in Cairo, Egypt, has built a solid reputation as a reliable manufacturer and supplier of top-notch stainless steel products, particularly known for their Stainless Steel 446 Hollow Bars. The company prides itself on delivering materials that are not only precision-engineered but also heat-resistant and corrosion-resistant, all while adhering to international standards. With cutting-edge production facilities and rigorous quality control measures, Neith Metals guarantees that their products consistently perform well and stand the test of time. Their Stainless Steel 446 Hollow Bars are crafted to provide outstanding oxidation resistance, mechanical strength, and dimensional stability, making them perfect for tough industrial, thermal, and engineering applications where reliability and durability are crucial.
Stainless Steel 446 Hollow Bars are ferritic stainless steel alloys characterized by a high chromium content (23–27%) and low carbon levels (≤0.20%), along with trace amounts of manganese, silicon, and molybdenum. This unique composition gives them remarkable resistance to oxidation, scaling, and sulfidation, even at high temperatures. On the mechanical side, they boast a tensile strength of about 550 MPa and a yield strength close to 350 MPa, all while maintaining stability under thermal stress. These bars are known for their exceptional toughness, hardness, and precise dimensions, making them ideal for high-temperature and moderately corrosive environments, ensuring long-lasting performance.
