We are leaders

Arnco Technology has led the hardbanding industry since pioneering the use of casing-friendly hardbanding two decades ago. We pride ourselves on protecting your drill string and casing assets by developing leading edge solutions for ultimate wear protection and crack-free products.


The technology behind Arnco’s outstanding hardbanding alloys stretches back to 1946 when its founder Roman F. Arnoldy developed and patented a hardfacing alloy that helped revolutionize wear protection.


In 1960, Roman developed and patented the Triten bulk welding process, which was the catalyst for the commercial exploitation of applying overlay alloys to steel plate, drastically reducing the failure rate of piping under high stress.



Since 1992, Arnco has developed a comprehensive suite of products that offer a wide range of performance characteristics to match your unique needs for drill string and casing wear protection.

The 350XT was introduced to the market. This innovative product is a highly compatible, crack free, and casing friendly hardband solution.
