Product Description
33NiCrMoV14-5 (Material Number 1.6952) is a high-performance, nickel-chromium-molybdenum-vanadium vacuum-melted alloy steel. It is engineered for applications requiring the absolute maximum in tensile strength, toughness, and hardenability, particularly in large cross-sections.
This steel is often categorized under the "Super High Strength" bracket and is frequently used in the power generation and aerospace industries.
Key Technical Specifications
1. Chemical Composition
The "V" in the designation indicates Vanadium, which refines the grain structure, while the high Nickel content ensures excellent impact toughness even at low temperatures.
-
Carbon (C): $0.30% - 0.37%$
-
Nickel (Ni): $3.30% - 3.80%$ (High toughness and hardenability)
-
Chromium (Cr): $1.20% - 1.50%$ (Corrosion resistance and hardness)
-
Molybdenum (Mo): $0.30% - 0.50%$ (Prevents temper brittleness)
-
Vanadium (V): $0.05% - 0.15%$ (Grain refinement)
2. Mechanical Performance (Typical Quenched & Tempered)
-
Tensile Strength ($sigma_u$): $1100 - 1300 text{ MPa}$
-
Yield Strength ($sigma_y$): $ge 900 text{ MPa}$
-
Elongation: $ge 13%$
-
Impact Energy (Charpy-V): High values even at $-40text{AC}$
Product Forms
Alloy Steel Bars & Rods
-
Processing: Usually supplied in black hot-rolled, peeled, or rough-machined condition.
-
Application: Used for high-stress shafts, turbine bolts, connecting rods, and heavy-duty axles.
-
Size Range: Commonly available from $phi 20 text{ mm}$ to $phi 500 text{ mm}$, though larger forged rounds can be custom-made.
Forged Rings
-
Processing: Produced via Seamless Rolled Ring Forging. This process aligns the grain flow circumferentially, which significantly increases the fatigue life and burst strength of the ring.
-
Application: Critical components for gas turbines, aerospace engine mounts, and high-pressure flanges.
Core Characteristics
-
Deep Hardenability: Unlike standard alloys, 33NiCrMoV14-5 can achieve uniform hardness through very thick sections (up to several hundred millimeters).
-
Fatigue Resistance: The vacuum-degassed melting process reduces impurities, leading to high fatigue strength under cyclic loading.
-
Thermal Stability: It maintains its mechanical integrity better than standard 4340 or 300M steels when exposed to moderately elevated temperatures.
Comparative Context
If you are moving between the materials weave discussed:
-
5082 Aluminium: For lightweight, corrosion-resistant marine structures.
-
2014 Aluminium: For high-strength aerospace skins/structures.
-
33NiCrMoV14-5 Steel: For the most extreme mechanical loads, where aluminium would simply fail due to stress or volume constraints.
Are you specifying this for a turbine component or a heavy-duty drivetrain application? This will help determine if you need it in the "Annealed" state for machining or "Pre-hardened" (T condition) for immediate use.
High Strength for Demanding Applications
33NiCrMoV14-5 Alloy Steel Bars, Rods, and Rings offer high tensile and yield strength, making them particularly suitable for parts subjected to heavy mechanical loads or impact. Their versatility means they are widely used in aerospace, power transmission, automotive industries, and in the fabrication of gears, shafts, and performance-critical engineering components.
Strict Quality Assurance and Certifications
Each batch undergoes rigorous ultrasonic inspection for internal soundness and is accompanied by test certificates as per EN 10204 3.1/3.2 and NABL-approved laboratory reports. This ensures every product delivered meets stringent international quality and material standards, adding reliability and assurance to end-users and manufacturers.
Custom Processing and Finishing Options
To meet diverse requirements, these alloy steel products can be supplied in various heat-treated states like annealed, hardened & tempered, or quenched & tempered. Surface finishes range from peeled and polished to bright or rough turned, with tight tolerances (h8, h9, h10) and customizable lengths/diameters possible, ensuring adaptability to different projects.
FAQ's of 33NiCrMoV14-5 Alloy Steel Bars / 33NiCrMoV14-5 Rods / 33NiCrMoV14-5 Rings:
