Neith Metals, located in Cairo, Egypt, has earned a solid reputation as a reliable manufacturer and supplier of top-notch OHNS (Oil Hardening Non-Shrinking) Round Bars. These bars are celebrated for their impressive hardness, wear resistance, and dimensional stability. The company is committed to crafting materials that adhere to global quality standards, serving a diverse array of industrial and engineering requirements. With state-of-the-art manufacturing technology and rigorous quality control measures, Neith Metals guarantees consistent performance and dependability. Their OHNS Round Bars find extensive application in the tool-making, automotive, and machinery sectors, where precision components demand durability and exceptional mechanical strength.
The composition of OHNS Round Bars primarily includes carbon (0.9–1.0%), manganese (1.0–1.2%), chromium (0.5–0.6%), and tungsten (0.5–0.7%), along with trace amounts of silicon and vanadium. These elements work together to deliver outstanding hardness and toughness after the oil hardening process, ensuring minimal dimensional distortion. In terms of mechanical properties, OHNS steel boasts a tensile strength ranging from 750 to 950 MPa and exhibits high wear resistance. It remains stable during heat treatment and machining, offering superior cutting performance and an extended tool life, making it perfect for crafting precision dies, punches, and cutting tools.

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.
OHNS Round Bars are widely utilized in the manufacturing of tools and dies, where precision and hardness are paramount. They are particularly well-suited for creating gauges, dies, punches, taps, reamers, cutting tools, and shear blades. In the automotive and mechanical industries, these bars are essential for producing shafts, spindles, and machine parts that endure friction and impact. Their remarkable dimensional stability and wear resistance also make them ideal for molds and forming tools. Furthermore, the machinability and oil-hardening characteristics of OHNS steel make it a favored option for components that require durability, sharpness retention, and reliable performance in demanding working conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
