Home > OHNS Round Bars
OHNS Round Bars, made of oil-hardened Non-shining steel, are known for their exceptional durability, corrosion resistance, and dimensional stability. These bars are ideal for precision tooling and die-forming applications because they hold their shape and size after hardening. Commonly used in the automotive, aerospace, and construction industries, OHNS spherical cylinders provide excellent mechanical durability, making them suitable for high-stress environments. Strict adherence to quality standards ensures these wooden rounds are reliable and durable. Whether for cutting tools, measuring instruments, or controls, OHNS round bars offer a reliable solution to complex industrial applications.

Yes, OHNS Round Bars, being tool steel, can be susceptible to galvanic corrosion when in contact with dissimilar metals in the presence of an electrolyte. To mitigate this risk, protective measures such as coatings, insulation, or using compatible metals are recommended. Regular maintenance and monitoring can also help prevent galvanic corrosion, ensuring the longevity and performance of OHNS round bars in various industrial applications.
