Introducing Virina’s First Turnkey Solution:
Nano Technology Grinding Balls
Virina proudly launches its first turnkey solution—Virina Steel Nano Technology Grinding Balls, engineered specifically for the Cement and Mining industries. Featuring uniform hardness from surface to core, these cutting-edge grinding balls deliver a transformative competitive advantage, setting a new standard in performance and durability.
Following a highly successful debut in the cement industries of Taiwan and China, Virina Nano Technology Grinding Balls have gained rapid traction. This momentum is now expanding globally, with Virina emerging as the fastest-growing grinding media supplier in the U.S. and Mexico as of 2016—and with continued global growth well underway.

Virina Grinding Ball Advantages
and Proven Performance
Virina Steel Grinding Balls are engineered using a proprietary alloy composition to produce high-carbon steel billets. These billets are then precision-forged and undergo a specialized heat treatment and cooling process. The result is a grinding ball with exceptional impact resistance, minimal deformation, and significantly extended wear life.
Virina’s cutting-edge Nano Technology Grinding Balls quickly gained traction in the cement industries of Taiwan and China upon their introduction. This early success is paving the way for continued adoption across the global cement and mining sectors. In 2016, Virina emerged as the fastest-growing grinding media supplier in the U.S. and Mexico, with robust international expansion well underway.

WHAT THE EXPERTS SAY

Mike Fec
Senior Metallurgical Engineer & Technical Manager
SGS MSi
In our analysis, ASTM 14 represents the finest grain size we typically report—indicating exceptional material quality. When we examined the Virina ball under 500x magnification, its grain structure was even finer than ASTM 14. This ultra-fine grain structure is a strong indicator of superior alloy strength, toughness, and long-term durability.
Based on our findings, the Virina ball is engineered to withstand cracking and deformation, offering exceptional reliability and performance in even the most demanding industrial applications

At SGS MSi, we recently had the opportunity to work with a sample of Virina Construction Steel certified to ASTM A1035 standards with a tensile strength of 1500 MPa. In over an hour of cutting just half of a 125 mm ball sample, our lab was truly put to the test—the material’s exceptional hardness and toughness were immediately apparent.
Despite using a high-powered abrasive saw, the sample's durability caused overheating, preventing us from completing the standard hardness test. This level of resistance is something we rarely encounter and is a testament to the steel’s superior performance characteristics.
Virina’s steel stands out as a truly elite material in terms of strength and resilience.

The metallurgical analysis of John’s material revealed outstanding structural integrity in both the hot rolled and quench & tempered states.
The fine grain structure was evident across all conditions, with 100% martensite and no retained austenite in the quenched samples—indicating a fully effective heat treatment process with no slack transformation products.
In the hot rolled condition, the microstructure showed an even 50/50 split between ferrite and pearlite, underscoring excellent phase balance and consistency.
This material demonstrates the type of quality and performance that’s rarely seen—an exceptional candidate for high-performance or critical applications
