25Cr2MoVA Alloy Steel Round Bar – Diameter 10–300mm | Custom Cut-to-Length for High-Temperature & High-Strength Applications
Overview
25Cr2MoVA is a premium-grade, low-alloy high-strength steel renowned for its exceptional mechanical properties, outstanding heat resistance, and excellent anti-creep performance at elevated temperatures. Widely specified in critical engineering sectors such as power generation, petrochemicals, aerospace, and heavy machinery, 25Cr2MoVA alloy steel round bar offers the perfect balance of strength, toughness, and thermal stability.
Our 25Cr2MoVA round bars are manufactured to meet stringent international standards (including GB/T 3077-1999 and UNS A31253) and are available in diameters ranging from 10 mm to 300 mm, with custom cutting in length to suit your exact project requirements—minimizing waste and accelerating production timelines.
Whether you're fabricating turbine rotors, high-pressure valves, or critical fasteners operating up to 550°C, our precision-engineered 25Cr2MoVA bars deliver reliability under extreme conditions.
Key Features & Benefits
- ✅ High tensile strength (≥930 MPa) and yield strength (≥785 MPa) after standard quenching & tempering
- ✅ Excellent impact toughness (≥63 J at room temperature)
- ✅ Stable mechanical properties up to 510–550°C
- ✅ Good hardenability and uniform microstructure across large cross-sections
- ✅ Suitable for nitriding surface treatment to enhance wear resistance
- ✅ Supplied in quenched & tempered (Q&T), annealed, or normalized + tempered conditions
- ✅ Custom lengths available (e.g., 1m, 2m, 3m, 6m, or project-specific dimensions)
- ✅ Full material test reports (MTRs), EN 10204 3.1/3.2 certification upon request
Typical Applications
25Cr2MoVA’s unique combination of strength, creep resistance, and thermal stability makes it ideal for:
- High-temperature fasteners: Bolts, nuts, and studs for steam turbines (≤550°C)
- Turbine components: Integral rotors, sleeves, main steam stop valves
- Valve stems and gears (especially when nitrided for surface hardness)
- Pressure vessels and piping systems in refineries and power plants
- Heavy-duty shafts and axles in industrial machinery
Chemical Composition (GB/T 3077-1999 Standard)
| Element | Content (%) |
|---|---|
| Carbon (C) | 0.22 – 0.29 |
| Silicon (Si) | 0.17 – 0.37 |
| Manganese (Mn) | 0.40 – 0.70 |
| Chromium (Cr) | 1.50 – 1.80 |
| Molybdenum (Mo) | 0.25 – 0.35 |
| Vanadium (V) | 0.15 – 0.30 |
| Phosphorus (P) | ≤ 0.035 |
| Sulfur (S) | ≤ 0.035 |
| Aluminum (Al) | ≤ 0.040 |
| Iron (Fe) | Balance |
The addition of Cr, Mo, and V enhances hardenability, high-temperature strength, and resistance to temper embrittlement.
Mechanical Properties (After Standard Q&T: 900°C Oil Quench + 640°C Air Cool)
| Property | Value (Typical) |
|---|---|
| Tensile Strength (Rm) | ≥ 930 MPa |
| Yield Strength (Rp0.2) | ≥ 785 MPa |
| Elongation (A5) | ≥ 14% |
| Reduction of Area (Z) | ≥ 55% |
| Impact Energy (Charpy V-notch) | ≥ 63 J @ 20°C |
| Hardness (HBW, Q&T condition) | 269 – 321 |
| Hardness (HBW, Annealed) | ≤ 241 |
Properties may vary slightly based on diameter and heat treatment cycle.

Why Choose Our 25Cr2MoVA Round Bars?
- Premium Metallurgy: Produced via electric arc furnace (EAF) + ladle refining + vacuum degassing (VD) for ultra-low inclusion content and superior fatigue life.
- Dimensional Accuracy: Tight tolerances on diameter and straightness ensure seamless integration into CNC machining and forging workflows.
- Traceability: Full heat number traceability from ingot to finished bar.
- Global Compliance: Meets or exceeds Chinese (GB), European (EN), and ASTM equivalency requirements.
- Technical Support: Our metallurgical engineers provide guidance on heat treatment, machining parameters, and welding procedures.
Machining & Heat Treatment Guidelines
- Machinability: Best performed in annealed or high-temperature tempered condition (HB ≤ 241). Use carbide-tipped tools and adequate coolant.
- Heat Treatment:
- Quenching: 880–910°C, oil quench
- Tempering: 600–660°C, air cool (critical: rapid cooling through 550–450°C range to avoid temper brittleness)
- Welding: Preheat to 250–300°C; use low-hydrogen electrodes (e.g., E7018-H4R); post-weld stress relief at 620–650°C recommended.
Frequently Asked Questions (FAQ)
Q: Is 25Cr2MoVA equivalent to any AISI/SAE grade?
A: It has no direct AISI equivalent but shares similarities with 4140 + V-modified grades. Its closest international counterpart is often considered 25CDV6 (French AFNOR) or custom Cr-Mo-V steels per ASTM A193 B16.
