Hastelloy C276 Round Bar Custom Cutting Alloy C276 Bar OD10 - 350mm Corrosion Resistant

Hastelloy C276 (designated as EN 2.4819 under European standards) is a premium nickel-molybdenum-chromium alloy renowned for its exceptional corrosion resistance in harsh environments. The small-diameter round bars (6-100mm) with a standard length of 6m combine this alloy's inherent performance advantages with dimensional precision, making them ideal for high-demand industrial applications where reliability and durability are critical.

• Tensile Strength: ≥730 MPa
• Yield Strength (0.2% offset): ≥310 MPa
• Elongation (in 50mm): ≥40%
• Hardness: ≤210 HB (Brinell) / ≤220 HV (Vickers)

Note: Mechanical properties can be adjusted via heat treatment (e.g., solution annealing at 1150-1175°C followed by rapid quenching) to enhance strength for high-stress applications.

The alloy's unique composition (high Mo, Cr, and W content) delivers outstanding resistance to:

• Oxidizing acids: Sulfuric acid (dilute to moderate concentrations)
• Reducing acids: Hydrochloric acid, phosphoric acid, and organic acids (e.g., acetic acid)
• Chloride-induced corrosion: Pitting, crevice corrosion, and stress corrosion cracking (SCC) in seawater, brines, or chloride-rich process streams
• High-temperature environments: Stable oxidation resistance up to 1040°C (2000°F) in air; maintains strength and corrosion resistance in high-temperature chemical reactors

The 6-100mm diameter, 6m length EN 2.4819 round bars are widely used in industries where corrosion resistance and dimensional precision are non-negotiable:

• Chemical Processing: Components for reactors, heat exchangers, valves, and piping (handling acids, solvents, and corrosive intermediates)
• Oil & Gas: Downhole tools, wellhead components, and offshore equipment (resistant to seawater and sour gas environments)
• Pharmaceutical & Food Processing: Sanitary piping, mixing blades, and reactor internals (compliant with high-purity and corrosion-free requirements)
• Pollution Control: Scrubber systems, flue gas desulfurization (FGD) equipment, and wastewater treatment components (resistant to acidic flue gases)
• Aerospace & Power Generation: High-temperature fasteners, turbine components, and combustion system parts (withstands elevated temperatures and oxidative media)
