Guardian® HB
Tool Joint Hardband
uIndustry Leading Material Achieves Industry First
Guardian® HB is the first tool joint hardband to provide minimum
casing wear while maintaining excellent tool joint protection.
uProven in Severe Wear Drilling Environments
Guardian® HB easily handles severe wear environments
encountered in reach, horizontal, deepwater and abrasive hard rock
drilling, making it the ideal choice of oil companies and drill pipe
owners for a complete range of original and after market applications.
Guardian® HB is based on NanoSteel’s patented and proprietary
Super Hard Steel® Nanotechnology
uNanotechnology Results in Superior Performance
microstructures containing grains that vary in size from hundreds of
microns to several millimeters.
High Toughness/Low Hardness Materials

Nanocrystaline materials are measured on nanoscale, or a length
scale of 1-100 nanometers (1 nm = 10-9 m).

Materials with High Hardness AND High Toughness
High Hardness/Low Toughness Materials
Guardian® HB is a nanocrystaline material which features
a microstructure containing near-nanoscale grains that yield
combined levels of high hardness and high toughness resulting in
wear performance never before achieved in a hardband material.

uSuperior Cracking Resistance
Guardian® HB has been engineered to contract and expand at the
same rate as the tool joint steel to virtually eliminate cracking during
shop and field applications.
Matching the coefficient of thermal expansion (CTE) of the hardband
material and base tool joint steel enables higher strength and
hardness without detrimental cracking tendencies.
Dye penetrant testing proves

crack resistance
Conventional hardbands have traditionally lowered their strength

uIndustry Leading Casing Wear Protection
The near-nanoscale grains in the microstructure of Guardian® HB
deliver the industry’s absolute best casing protection.
In DEA 42 tests, Guardian® HB shows a 37% reduction in casing
wear over the nearest “casing friendly” competitor.

“casing friendly” hardband product.
In DEA 42 tests, Guardian® HB shows a 55% improvement in radial
tool joint wear in casing compared to the second best performer.
uEasy Reapplication Over Itself
When considering the long-term cost of drill pipe ownership,
reapplication of the hardband is important.
