From the heart of Kinshasa, Sadiki Metals stands as a trusted partner for industry, dedicated to providing robust and reliable materials that power progress. Our commitment to quality and local expertise shines through in every product we supply, especially our OHNS round bars. We understand that the backbone of any great project is the integrity of its materials, which is why we focus on delivering steel that meets the demanding challenges of the Congolese industrial landscape, ensuring our clients can build with confidence.
The strength of our OHNS round bar comes from its carefully balanced composition, primarily a blend of carbon, manganese, chromium, and tungsten. This specific recipe gives the steel its notable hardness and exceptional resistance to wear, even under high-stress conditions. After a precise heat treatment process, it achieves a remarkable toughness, making it less prone to chipping or cracking under impact. This combination of durability and resilience is what sets this material apart for the most demanding tasks.

OHNS (Oil Hardened Non-Shrinking) round bars are sized based on their diameter, typically ranging from 6 mm to 300 mm, with standard lengths ranging from 3 meters to 6 meters.
OHNS (Oil Hardened Non-Shrinking) rods are available in different grades, such as OHNS 1, OHNS 2, and OHNS 3, varying in hardness, toughness, and application suitability for manufacturing and toolmaking.
Yes, laser welding can be used for OHNS (Oil Hardened Non-Shrinking) bar, as it offers precision, minimal heat input, and controlled weld quality, making it suitable for hardenable tool steels.
You’ll find our OHNS round bars hard at work in the tools that shape other materials. They are the ideal choice for crafting everything from punches and dies that stamp out metal parts, to a variety of forming tools and blades that require a sharp, long-lasting edge. Their ability to withstand significant abrasion and pressure makes them indispensable in metalworking, manufacturing, and the tool and die industry, forming the critical components that keep production lines moving efficiently and reliably.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
