45MnMoB Grade Drilling Pipe: The Hard-Core Solution for Extreme Conditions
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.
Core Advantages
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.
Why Choose 45MnMoB?
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.
Applications include fore poling (advance support), mine blasting, water well drilling, geothermal well drilling, and coal/nonferrous metal mining.
