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 %)

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)

These properties ensure excellent formability, weldability, and structural reliability under demanding service conditions.

Product Standards & Certifications

Our Hastelloy C276 round bars comply with the following global specifications:

• ASTM B574: Standard Specification for Nickel-Molybdenum Alloy Rod

Common Applications

Hastelloy C276 round bars are used to fabricate critical components in the most corrosive environments:

• Chemical Processing: Reactors, agitators, shafts, valves, pump parts
• Flue Gas Desulfurization (FGD): Scrubber internals, dampers, fans
• Oil & Gas: Downhole equipment, sour gas service components
• Pharmaceutical & Pulp/Paper: Bleaching vessels, digesters
• Waste Treatment: Acid neutralization systems
• Marine Engineering: Seawater piping, heat exchangers
• Nuclear Industry: Fuel reprocessing equipment

Its ability to withstand mixed acids, hot seawater, and contaminated process streams makes it indispensable in high-integrity systems.
