Our products have been granted Certificate of Authority to use the
Official API Monogram with license number *******2, ISO***1:***0
Certificate of Quality Management System and ISO****0 Certificate
of Occupational Health and Safety Management System.
Strict control of chemical composition and low temperature forging
guarantee the excellent mechanical properties of our non-magnetic
products.
Tensile strength is ****0 percent higher than the requirement of
API Spec **1.
Minimum Brinell Hardness is above **5 and minimum impact values is
over **0 Joules.
Our non-magnetic products are highly corrosion-resistant, which
greatly extends the service life of drilling tools in a corrosive
atmosphere.
The maximum relative magnetic permeability of non-magnetic tools
can be controlled to less than 1.**5 (API standard 1.*1), which
increases the accuracy of measurements taken during directional
drilling.
