Product Description

Werkstoff-Nr. 1.6546 (commonly designated in the EN system as 40NiCrMo2-2 or NiCrMo2-2) is a high-performance, medium-carbon nickel-chromium-molybdenum low-alloy structural steel.

Unlike the case-hardening 14 220 or 15HG grades, 1.6546 is optimized for quenching and tempering (through-hardening). The deliberate combination of nickel (for impact toughness), chromium (for depth hardenability), and molybdenum (to mitigate temper brittleness) gives this steel excellent uniform tensile properties across thick cross-sections.

Global Cross-Reference & Equivalents

When specifying or substituting WNr 1.6546 round bars or rods across international standards, use these direct equivalents:

Standard System	Designators / Equivalents
W.Nr. / EN (Germany/Europe)	1.6546 / 40NiCrMo2-2 (formerly NiCrMo2-2)

Chemical Composition (Typical wt.%)

The carbon range positions this material perfectly for thorough hardening, while the multi-alloy system achieves robust grain refinement.

Carbon (C): 0.37% -0.44%
Nickel (Ni): 0.40% - 0.70%
Chromium (Cr): 0.40% - 0.60%
Manganese (Mn): 0.50% - 1.00%
Molybdenum (Mo): 0.15% -0.30%
Silicon (Si): 0.15% - 0.40%
Phosphorus (P): 0.035%
Sulfur (S): 0.035%

Technical Specifications & Supply Conditions

1.6546 round bars and rods are primarily distributed in one of two major processing formats:

1. Common Delivery States

Annealed (+A): Spheroidized or soft-annealed state to keep hardness low ( $le$ 250 HBW) for automated cold-sawing, machining, or cold-heading.
Quenched and Tempered (+QT): Pre-hardened at the mill to bring out its high-strength mechanical properties directly before final processing.

2. Standard Mechanical Properties (Typical in +QT Condition)

Tensile Strength ( $R_m$ ): 885 1100 MPa
Yield Strength ( $R_e$ ): $ge$ 725 MPa
Elongation ( $A_5$ ): $ge$ 16% 25% (depending on product form)
Hardness (Post Oil-Quench): Can achieve 4552 HRC at the surface/mid-radius depending on bar diameter.

Core Industrial Applications

Because 1.6546 maintains outstanding fatigue resistance and high structural integrity under severe torsion and bending stresses, it is a staple material in demanding mechanical applications:

High-Strength Fasteners: Heavy-duty turbine fasteners, boiler support rods, and aerospace engine studs/bolts (frequently matching AMS aircraft specifications).
Power & Motion Transmission: Main drive shafts, multidiameter axles, connecting rods, high-load mechanical gears, and valve stems.
Oil & Gas / Process Plants: High-stress manifold bolts, pressure vessel components, and heavy structural hardware.

Superior Mechanical Properties

1.6546 Alloy Steel Bars are heat treated-normalized, quenched, and tempered-to meet rigorous performance benchmarks. They deliver a high tensile strength of 900-1100 MPa and a hardness between 250-320 HB, ensuring durability and resistance to wear in high-stress environments. This makes them especially suitable for precision components like shafts and gears.

Flexible Sizing and Finishes

Available in a comprehensive range of diameters from 18mm up to 280mm and in lengths of 100mm to 6000mm, these bars can be supplied in black, bright, peeled, or polished finishes. With tolerance options such as H8, H9, and h10, they can be customized to meet project-specific requirements. Ends are offered square cut or machined for added convenience.

Versatile Applications Across Industries

WNr 1.6546 Alloy Steel Rods serve critical roles in construction, automotive, engineering, and heavy machinery sectors. Their exceptional mechanical properties and adaptability make them the preferred choice for manufacturers, fabricators, and engineers needing reliable materials for high-stress applications, including the production of gears, shafts, and robust machinery components.

FAQ's of WNr 1.6546 Alloy Steel Bar 1.6546 Round Bars 1.6546 Rods:

Q: How are WNr 1.6546 alloy steel bars processed to achieve their mechanical properties?

A: These alloy steel bars undergo normalization, quenching, and tempering heat treatments. This process enhances their hardness (250-320 HB) and tensile strength (900-1100 MPa), ensuring they can endure demanding operational conditions.

Q: What are the principal applications for 1.6546 alloy steel bars and rods?

A: 1.6546 alloy steel is widely utilized in manufacturing shafts, gears, and components subjected to high stress. Industries such as construction, automotive, engineering, and heavy machinery benefit from its reliability and strength.

Q: When should I choose 1.6546-grade alloy steel over other grades?

A: Select 1.6546 alloy steel when you require a material with excellent strength, fatigue resistance, and toughness, particularly in applications involving cyclic loading or high stress. It is ideal for critical-engineering parts needing consistent mechanical performance.

Q: Where are these alloy steel bars commonly manufactured and supplied from?

A: WNr 1.6546 alloy steel bars are produced and exported by manufacturers, suppliers, and traders in India. They are available globally, meeting international standards like DIN, ASTM, and EN for diverse industrial usage.

Q: How does the surface condition and finish affect the usability of 1.6546 steel rods?

A: With options including smooth, bright, black, peeled, and polished finishes, as well as freedom from scale, these surface conditions enhance the rods' appearance and performance. A cleaner surface also assists in further machining and reduces susceptibility to corrosion.

Q: What is the benefit of ordering bars in custom lengths and tolerances?

A: Custom lengths (100mm-6000mm) and strict tolerance control (H8, H9, h10) ensure the material precisely fits the end application, minimizing additional fabrication and reducing overall project lead times.
