ASTM EN GB JIS Standard Hastelloy C276 Bright Polished Bar Hot Rolled and Forged Round Bars
Hastelloy C276 bright polished round bars stand as a pinnacle of high-performance nickel-chromium-molybdenum alloys, engineered to excel in the most demanding industrial environments. Combining exceptional corrosion resistance, robust mechanical strength, and consistent dimensional precision, these hot-rolled and forged bars meet global standards including ASTM, EN, GB, and JIS, making them a preferred choice across critical sectors worldwide.
Core Properties and Performance Advantages
At the heart of Hastelloy C276’s superiority lies its meticulously balanced chemical composition. Dominated by nickel (balance content), it integrates 14.5-16.5% chromium, 15.0-17.0% molybdenum, 3.0-4.5% tungsten, and 4.0-7.0% iron, with strict limits on carbon (0.02% max) and cobalt (2.5% max) . This formulation delivers unparalleled resistance to pitting, crevice corrosion, and stress-corrosion cracking in both oxidizing and reducing media—from sulfuric acid in chemical plants to chloride-rich marine environments .
High-temperature stability further distinguishes these bars, which maintain structural integrity up to 1040°C. With a density of 8.89 g/cm³ and modulus of elasticity of 205 GPa, they offer a rare combination of ductility and strength: annealed bars achieve 455 MPa yield strength and 842 MPa tensile strength with 40% elongation, while cold-worked variants reach up to 1724 MPa yield strength . The bright polished finish enhances these properties by eliminating surface imperfections that could initiate corrosion, ensuring long-term performance in harsh conditions.
Global Standards Compliance
Adherence to international standards guarantees consistency and interoperability across projects. The table below outlines key specifications:
| Standard System | Relevant Grade | Key Specification | Dimensional Tolerance |
|---|---|---|---|
| ASTM/ASME | UNS N10276 | ASTM B574 | H8-H13, K9-K12 |
| EN/DIN | 2.4819 | EN 10088-3 | H8-H13, K9-K12 |
| GB | N06276 | GB/T 15007 | H8-H13, K9-K12 |
| JIS | NW276 | JIS G4902 | H8-H13, K9-K12 |
All bars undergo rigorous testing, including chemical composition analysis, mechanical property verification, and surface finish inspection, with certificates such as ISO, SGS, and EN 10204-3.1 available on request .
Product Specifications
Dimensions and Forms
Hastelloy C276 bright polished round bars accommodate diverse industrial needs with flexible sizing:
- Diameter Range: 3.17 mm to 350 mm (hot-rolled: 10-250 mm; cold-drawn: 4-60 mm)
- Length: 100 mm to 6000 mm, with custom cutting available
- Finish: Bright polished (Ra ≤ 0.8 μm), with options for BA finish or No.4 finish
- Processing: Hot-rolled for larger diameters, forged for enhanced grain structure, and cold-drawn for tight tolerances
Mechanical Properties (Typical Values)

Industrial Applications
The versatility of Hastelloy C276 bright polished bars makes them indispensable across high-stakes industries:
- Petrochemical & Oil/Gas: Used for valves, pump shafts, and reactor internals, resisting sour gas and chloride corrosion .
- Chemical Processing: Ideal for agitators and heat exchanger components in environments with sulfuric, hydrochloric, and acetic acids .
- Pharmaceuticals & Food Processing: Meets hygiene standards for equipment requiring corrosion resistance and easy cleaning .
- Aerospace & Energy: Fabricated into turbine parts and nuclear reactor components, enduring extreme temperatures and pressure .
Quality Assurance and Packaging
Each bar features permanent marking with material grade, heat code, manufacturer symbol, and standard designation for traceability . Packaging includes waterproof paper and plastic foil wrapping to prevent contamination during transit, with custom crating available for large orders. Minimum order quantity starts at 10 kgs, with a supply capacity of 500 tons monthly to support both small-batch and bulk requirements .
Backed by global standards compliance and proven performance in harsh environments, Hastelloy C276 bright polished round bars deliver reliability where material failure is not an option. Whether for chemical processing equipment or aerospace components, these bars combine precision engineering with exceptional durability.
