Situated in the heart of Addis Ababa, Tariku Metals has established itself as a trusted local source for high-performance materials, directly supplying industry with essential components. We specialize in providing robust Hastelloy B2 forgings, a niche yet critical product for demanding industrial environments. Our focus is on delivering not just a product, but a reliable solution that supports the growth and integrity of local engineering projects, ensuring our clients have access to world-class materials backed by our dedicated service and deep understanding of the regional market’s unique needs.
Hastelloy B2 is a nickel-molybdenum alloy specifically engineered to handle some of the toughest chemical challenges. Its composition provides outstanding resistance to hydrochloric acid across a wide range of concentrations and temperatures, along with excellent performance in other non-oxidizing media. Mechanically, these forgings are incredibly strong and durable, offering high tensile strength and good ductility even under extreme thermal stress. This combination allows them to maintain their structural integrity in environments that would quickly degrade lesser materials.

Hastelloy C22 Nuts are the go-to choice for environments that involve strong chemicals, high temperatures, and severe corrosion. They are commonly found in the chemical processing sector, including reactors, heat exchangers, piping systems, and evaporators that come into contact with chlorides, acids, and various chemical mixtures. Pollution control equipment, waste treatment facilities, and flue-gas scrubbers depend on these nuts for their long-lasting performance. In the pharmaceutical and food industries, C22 nuts are favored for their ability to maintain purity and prevent contamination.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
