EN10305-1 Steel Drilling Rod 45MnMoB Grade Seamless Steel Oil Well Drilling Pipe With Coupling Tube

​45MnMoB Grade Drilling Pipe: Unmatched Strength & Specialized Performance for Demanding Oilfield Applications​​
      The ​​45MnMoB-grade drilling pipe​​ is a ​​high-performance alloy steel solution​​ engineered for oilfield operations that demand ​​exceptional strength, superior wear resistance, and enhanced impact toughness​​. With its unique chemical composition (notably ​​high manganese and molybdenum content​​) and tailored mechanical properties, this grade stands out as an optimal choice for ​​extreme drilling environments​​ where standard grades fall short.

 

Why Choose 45MnMoB-Grade Drilling Pipes?​​
1. Built for Extremes​​ – Delivers ​​unmatched strength and wear resistance​​ for ​​high-load, high-wear drilling scenarios​​ where standard grades fail.

 

2. Alloy-Optimized​​ – Manganese and molybdenum enhance ​​hardenability, high-temperature stability, and fatigue life​​ – critical for modern deep drilling.

 

3. ​​Tailored Hardness​​ – Optional ​​QT treatment​​ pushes surface hardness to ​​32 HRC​​, combating abrasion and extending service intervals.

 

4. Reliable in Harsh Fluids​​ – Low sulfur/phosphorus and fine microstructure resist ​​corrosion and erosion​​ in aggressive well environments.

 

​​45MnMoB-Grade Drilling Pipes – When your well demands more than ordinary steel can handle.​

 

Applications include fore poling (advance support), mine blasting, water well drilling, geothermal well drilling, and coal/nonferrous metal mining.​​
