Description
SAE4130 Steel Drill Rod Geological Exploration Wireline Pipe
SAE4130 Steel Drill Rod for Geological Exploration Wireline Pipe is a high-strength alloy steel drill rod engineered for wireline drilling in geological exploration. Crafted from SAE4130 steel (equivalent to 42CrMo), it delivers exceptional tensile strength (≥800 MPa) and yield strength (≥690 MPa) after quenching-tempering, ensuring durability in abrasive rock formations. Precision-machined with tight tolerances (OD ±0.1mm, straightness ≤0.3mm/m) and a smooth inner surface (Ra ≤1.6μm), it minimizes friction and torque loss. Features robust thread connections (e.g., API NC50) for secure assembly, optional corrosion-resistant coatings (nitriding/phosphate), and adaptability to deep-hole drilling in complex geologies (hard rock, gravel, clay). Ideal for core sampling and mineral exploration, balancing strength, precision, and reliability.
