Engineered specifically for ultra-deep wells, high-pressure reservoirs, and highly abrasive formations, the 45MnMoB-grade drilling pipe combines a high-manganese-molybdenum alloy composition with enhanced mechanical properties to deliver unmatched reliability in challenging drilling environments.
1.Extreme Load-Bearing
Tensile strength ≥790 MPa, hardness up to 28–32 HRC (after quenching & tempering), ensuring reliable performance in ultra-deep wells (>3,000m) and high-pressure formations (≥50 MPa).
2.Wear & Corrosion Resistance
High manganese (1.05–1.35%) and molybdenum (0.20–0.25%) content enhance abrasion resistance, while a refined microstructure improves fracture toughness for extended service life in harsh conditions.
3.Balanced Toughness
Elongation ≥14% balances strength and ductility, effectively absorbing sudden impacts (e.g., stuck pipe, vibration) to prevent brittle failure.
4.Specialized Adaptability
Optimized for hard rock, high-sand content, and complex formations. Optional quenching & tempering (QT) treatment further increases surface hardness (up to 32 HRC) for enhanced durability.
Tougher and more wear-resistant than conventional carbon steels (e.g., 1541), yet more cost-targeted than 4130/4140—designed specifically for high-demand drilling scenarios.
Mn-Mo alloy formula + precision engineering ensures high-temperature stability and fatigue resistance, meeting modern deep-well requirements.
45MnMoB Grade – When standard steel can’t keep up, this is the answer.
(Ideal for: Ultra-deep wells, high-pressure extraction, abrasive formations. Budget-friendly or shallow wells: Consider 1541; balanced performance: Opt for 4130/4140.)
