For manufacturers and engineers in Addis Ababa, finding a trusted local source for high-performance materials is essential. Tariku Metals stands as that reliable partner, dedicated to supplying top-quality Stainless Steel 440C bars and rods. We understand the demands of Ethiopia’s growing industrial sector, and our commitment is to provide materials that meet rigorous standards, ensuring your projects are built on a foundation of durability and precision right here in our capital city.
The strength of 440C stainless steel comes from its specific composition, primarily high carbon and chromium content. This gives the material an exceptional balance of hardness and corrosion resistance. Through proper heat treatment, these bars and rods achieve remarkable wear resistance, making them significantly tougher than many other stainless grades. This reliable combination of properties ensures they can withstand demanding environments without compromising their structural integrity.

Stainless Steel 440C Bars and Rods are known for their high hardness, achieving up to 58-60 HRC when heat-treated. This makes them ideal for applications requiring excellent wear and abrasion resistance.
Stainless Steel 440C offers good corrosion resistance in mild environments, but for more aggressive conditions (like exposure to saltwater), it is recommended to use more corrosion-resistant stainless steel grades like 316 or 317.
This versatile grade is the preferred choice for applications where failure is not an option. You will find 440C bars and rods at the heart of precision tools, high-performance bearings, and durable valve components. They are equally crucial in the medical field for surgical instruments and in the food processing industry for machinery parts that must resist constant wear and cleaning. Essentially, any project requiring a material that is both hard and resilient will benefit from the exceptional qualities of 440C stainless steel.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
