Protanium High Torque Steel article


ProtaniumTM Steel

ProtaniumTM Steel is proprietary alloy steel developed and used only by BONDHUS.  It is not common alloys such as 8650.  The hardness values of up to 60 RC (and above).

It is the hardest, most ductile, and longest wearing steel that exists in the hex tool industry. Up to 20% stronger, with more torque and twice the wear resistance of standard grades of steel.

Bondhus uses ProtaniumTM High Torque Steel on all of its standard tools.

Steel considerations:

8650 is the most common steel alloy in use thoughout the US and the Far East.  It does not have the hardness or ductility of ProtaniumTM Steel.

Chrome Vanadium is comparable in quality to 8650, and often used in Europe.

1050 carbon steel is a low grade steel that is inferior to those listed above.
