3 Reasons to Choose Baowu BS700MCK2 High-Strength Steel for Your Projects
Unmatched Strength & Toughness for Demanding Environments
BS700MCK2 is Baowu Steel Group’s flagship high-strength structural steel, engineered for critical applications where reliability is non-negotiable. Its exceptional properties include:
1) 700MPa Minimum Yield Strength – With tensile strength ≥750MPa, it significantly outperforms conventional structural steels, enabling lighter designs without compromising safety
2) Superior Formability & Weldability – Low carbon content (C≤0.12%) and micro-alloying (Nb/V/Ti≤0.22%) enable seamless cold forming and crack-free welding without preheating
3) -20°C Impact Toughness (K2 Grade) – Delivers ≥40J impact energy at -20°C, ensuring structural integrity in freezing climates or cryogenic applications-20°C Impact Toughness (K2 Grade) – Delivers ≥40J impact energy at -20°C, ensuring structural integrity in freezing climates or cryogenic applications
Why It Matters: Replace thicker conventional steel with BS700MCK2 to reduce weight by 15–30% while maintaining or enhancing load capacity – ideal for mobile equipment and dynamic structures
Equivalent Grades of BS 700MC K2/K4
Certified Quality from China’s Steel Leader
BS700MCK2 adheres to Baowu’s stringent enterprise standard Q/BQB 316-2014, guaranteeing traceability and consistency:
1) Advanced TMCP Process – Controlled rolling and cooling technology refines the microstructure (ferrite + acicular ferrite) for uniform strength and toughness
2) Rigorous Quality Control – Oxygen-converter smelting, ladle refining, and automated slab inspection ensure near-zero defects (e.g., segregation, inclusions)
3) Full Compliance Documentation – Mill test certificates validate chemical composition, mechanical properties, and impact test results for every batch
Industry Trust: Trusted by Caterpillar, XCMG, SANY, and other global OEMs for mining shovels, crane booms, and military vehicle frames
