Hastelloy C276 Round Bar Custom Cutting in Length UNS N10276 Alloy 276 With EN 10204-3.1 Certificate
Product Overview
Hastelloy® C276 (UNS N10276, W.Nr. 2.4819) is a premium nickel-molybdenum-chromium-tungsten alloy renowned for its exceptional corrosion resistance across a wide range of aggressive chemical environments—both oxidizing and reducing. Our Hastelloy C276 round bars are precision-manufactured to meet international standards and can be custom-cut to your exact length requirements, ensuring seamless integration into your industrial applications. Each batch is supplied with an EN 10204-3.1 Mill Test Certificate, guaranteeing full traceability, chemical compliance, and mechanical integrity.
Ideal for use in chemical processing, oil & gas, pollution control, and marine engineering, C276 round bars offer unmatched durability in the presence of chlorides, acids, and high-temperature corrosive media.
Chemical Composition (Weight %)
| Element | Content (%) |
|---|---|
| Nickel (Ni) | 52.0 – 60.0 |
| Molybdenum (Mo) | 15.0 – 17.0 |
| Chromium (Cr) | 14.5 – 16.5 |
| Iron (Fe) | ≤ 5.0 |
| Tungsten (W) | 3.0 – 4.5 |
| Carbon (C) | ≤ 0.01 |
| Manganese (Mn) | ≤ 1.00 |
| Silicon (Si) | ≤ 0.08 |
| Phosphorus (P) | ≤ 0.040 |
| Sulfur (S) | ≤ 0.030 |
| Cobalt (Co) | ≤ 2.5 |
Note: C + S ≤ 0.05% as per ASTM B574.
This balanced composition provides superior resistance to pitting, crevice corrosion, and stress corrosion cracking—even in wet chlorine, hypochlorite, and chloride-rich environments.
Mechanical Properties (Typical at Room Temperature)
| Property | Value |
|---|---|
| Tensile Strength (Rm) | ≥ 690 MPa (100 ksi) |
| Yield Strength (Rp0.2) | ≥ 283 MPa (41 ksi) |
| Elongation (A5) | ≥ 40% |
| Hardness (HB) | ≤ 241 |
| Density | 8.9 g/cm³ |
| Melting Range | 1325–1370°C (2417–2498°F) |
These properties ensure excellent formability, weldability, and structural reliability under demanding service conditions.
