Author : Nickle steel | Published On : 13 Apr 2026
The 34CrNiMo6 1.6582 round bar is a high-strength alloy steel used in heavy-duty engineering applications. Piyush Steel India supplies certified 34CrNiMo6 round bars in a wide range of sizes, with full material traceability and fast delivery across India and globally.
If you're sourcing alloy steel for high-stress mechanical components, the 34CrNiMo6 1.6582 round bar is one of the most trusted materials in the industry. It offers a rare combination of toughness, tensile strength, and fatigue resistance that standard carbon steels simply can't match.
At Piyush Steel India, we stock and supply 34CrNiMo6 round bars to manufacturers, fabricators, and engineering firms across India and worldwide.
What Is 34CrNiMo6 1.6582 Round Bar?
The 34CrNiMo6 round bar is a chromium-nickel-molybdenum alloy steel defined under the EN 10083-3 standard. It delivers superior mechanical performance after quenching and tempering, making it ideal for components that face heavy cyclic loads and high torque.
Key elements in its chemical composition include chromium (1.3–1.7%), nickel (1.3–1.7%), and molybdenum (0.15–0.30%). These alloying elements work together to give the material its signature strength and toughness, even at large cross-sections.
Where Is 34CrNiMo6 Round Bar Used?
This alloy steel grade is widely used across demanding industries, including:
- Automotive: crankshafts, drive shafts, gear shafts
- Oil and Gas: drilling equipment, pump shafts, valve stems
- Aerospace: structural components, landing gear parts
- Heavy Engineering: power transmission shafts, hydraulic cylinder rods
- Marine: propeller shafts and coupling components
Its ability to maintain high strength under fatigue and impact makes it a preferred choice for rotating and load-bearing parts.
Mechanical Properties of 34CrNiMo6 1.6582
After heat treatment (quench and temper), 34CrNiMo6 round bar typically achieves:
- Tensile Strength: 1000 to 1200 MPa
- Yield Strength: minimum 800 MPa
- Elongation: around 11% (minimum)
- Hardness: 300 to 350 HB
These values make it one of the strongest readily weldable engineering steels available in bar form.
