The working hardness of VMO Steel typically ranges between 180 to 220 Brinell Hardness Number (BHN). This range makes it suitable for hot work applications, providing a good balance of strength and toughness. This steel grade is the upgrade version of DIN 2713 for better performance.
Applications
VMO steel is often used in environments requiring materials to withstand extreme stress, heat, or wear. This makes it a preferred choice in:
- Automotive:For parts like gears, crankshafts, and connecting rods.
- Aerospace:In high-performance aircraft parts that require both strength and resistance to extreme conditions.
- Oil & Gas: For components used in drilling and extraction equipment, where both high strength and resistance to corrosion are critical.
The equivalent steel grade.
- ABNT VMO
- DIN 2714
- SKT4

VMO Special Steel Common Properties:
- High Strength: VMO steel has excellent tensile strength due to the presence of alloying elements like Vanadium and Molybdenum. It can handle heavy loads and resist deformation under stress.
- Toughness:This steel grade exhibits superior toughness, meaning it can absorb energy and withstand impacts without breaking or cracking.
- Wear Resistance: VMO steel’s composition makes it highly resistant to wear, ensuring longer service life in applications involving friction or repeated mechanical stress.
- Corrosion Resistance: The presence of Molybdenum and Chromium provides excellent resistance to corrosion, particularly in harsh or high-temperature environments, making it ideal for chemical, oil & gas, and marine industries.
- Fatigue Resistance: This steel performs well under cyclic loads, meaning it can endure repeated stress without weakening, which is important for parts like gears or shafts.
