Engineered for ultra-deep, high-pressure, and abrasive drilling environments, 45MnMoB-grade drilling pipe combines exceptional strength, superior wear resistance, and enhanced toughness to tackle the toughest challenges.
1. Extreme High Strength
Tensile ≥790 MPa, Yield ≥600 MPa – Reliable in ultra-deep wells (>3,000m) and high-pressure reservoirs (≥50 MPa), outperforming standard grades.
2. Premium Wear Resistance
Manganese (1.05–1.35%) & Molybdenum (0.20–0.25%) – Boosts hardness (QT-treated up to 28–32 HRC) to resist drill cuttings and hard rock abrasion.
3. Balanced Toughness
Elongation ≥14% – Absorbs shocks (e.g., stuck pipe, vibrations) without cracking.
4. Corrosion & Heat Resilience
Low S/P (S≤0.015%, P≤0.020%) – Resists corrosion in harsh fluids; molybdenum enhances high-temperature stability.
5. Weldable & Machinable
Controlled welding process (preheat for thick sections) and efficient machining for field adaptability.
Built for extremes – Outmatches 4130/4140 in wear resistance, beats 1541 in strength.
Alloy-optimized – Manganese/molybdenum duo ensures durability in high-impact, high-temperature wells.
Customizable hardness – QT treatment extends service life in abrasive zones.
For ultra-deep, high-wear, or HPHT wells, 45MnMoB is the ultimate choice.
