ZK95CrMo, ZK55SiMnMo, ZK40SiMnCrNiMo Hollow Drill Steel for Mining Rock Drilling Rods
Product Spotlights
Our products include hexagonal hollow steel bars and hollow steel blanks with uniform wall thickness and stable internal structure.
ZK95CrMo is mostly used for drill bits and medium-load drill pipes with continuous operation requirements.
ZK55SiMnMo is widely applied to shallow hole drill rods for road construction and stone exploitation.
ZK40SiMnCrNiMo matches large hydraulic drilling equipment working in complicated hard rock formations.
We provide fixed-length cutting, straightening, flaw inspection and surface treatment with full physical and chemical test documents.
The steel is wrapped with anti-rust paper and fastened with steel strips; finished products are loaded into sealed wooden frames to avoid collision damage and seawater corrosion in international sea transportation.
