Product Description
Technical Overview
15NiCr1Mo12 is a high-performance Nickel-Chromium-Molybdenum alloy steel known for its exceptional toughness and core strength. It is primarily used for parts requiring high surface hardness after carburizing, combined with a very strong and ductile core to withstand heavy shock loads.
Key Specifications & Properties
| Feature | Details |
| Material Number | 1.6723 |
| Standard | EN 10084 / DIN 17210 |
| Chemical Composition | Nickel (2.80% 3.30%), Chromium (0.60% 0.90%), Molybdenum (0.15% 0.30%) |
| Core Tensile Strength | $1100 - 1450 text{ MPa}$ (after heat treatment) |
| Condition | Annealed / Case Hardened |
Industrial Applications
Because of its high fatigue strength and resistance to wear, 15NiCr1Mo12 round bars are used for:
-
Heavy-Duty Gearing: High-load gears, crown wheels, and pinions.
-
Automotive & Aerospace: Critical drivetrain components and crankshafts.
-
Mining & Drilling: Heavy-duty shafts and connecting rods subjected to extreme impact.
-
Machine Tools: High-precision spindles and wear-resistant mechanical parts.
Features to Highlight in Your Listing
-
Extreme Core Toughness: Unlike standard steels, this maintains high ductility even at very high strength levels.
-
Superior Case Hardening: Ideal for carburizing to achieve a high-wear surface ($58-62 text{ HRC}$).
-
Shock Load Resistance: Specifically engineered to prevent brittle failure under sudden impact.
-
Premium Machinability: When supplied in the annealed state, it allows for high-precision machining before final hardening.

FAQ's of 15NiCr1Mo12 Alloy Steel 15NiCr1Mo12 Round Bars:
Q: How are 15NiCr1Mo12 Round Bars manufactured and heat treated?
A: These round bars are produced through hot rolling, forging, or cold drawing, followed by heat treatments like case hardening, quenching, and tempering. This process enhances core toughness, surface wear resistance, and achieves a fine-grained, homogeneous microstructure with hardness up to 62 HRC.Q: What makes 15NiCr1Mo12 Alloy Steel suitable for automotive and engineering components?
A: Their high tensile and yield strength, exceptional hardness, superior impact value (>35 J at -20C), and excellent toughness make them ideal for demanding components such as gears, shafts, axles, and pinions. The steel's durability ensures longevity and reliability in critical applications.Q: When should I choose a specific surface finish like bright or polished?
A: The choice of finish depends on application requirements. A bright or polished surface ensures minimal friction and aesthetic appeal for visible or precision parts, while black or peeled finishes offer robust corrosion protection for structural or hidden components.Q: Where can I use these round bars effectively?
A: 15NiCr1Mo12 steel round bars are widely used in automotive, heavy engineering, and power transmission industries for components that demand high strength, wear resistance, and dimensional accuracy, including gears, axles, and shafts.Q: What certifications are available for these alloy steel round bars?
A: Each bar is supplied with EN 10204 3.1/3.2 test certificates, ensuring quality conformity, traceability, and compliance with international standards, which is crucial for projects requiring documented assurance.Q: How does soft annealing affect the machinability of the steel?
A: Soft annealing the 15NiCr1Mo12 bars relieves internal stresses and lowers hardness temporarily, making the material much easier to machine before final hardening processes are applied.Q: What are the main benefits of using 15NiCr1Mo12 Alloy Steel Round Bars in fabrication?
A: They offer an optimal combination of strength, toughness, wear resistance, and precision, with customizable sizes, finishes, and verified tolerances, resulting in dependable solutions for high-performance engineered components.Tell us about your requirement
