Material Description
ASTM B574 Hastelloy C276 Bright Bar is a high-performance nickel-chromium-molybdenum alloy engineered for industrial machinery parts requiring exceptional corrosion resistance, mechanical strength, and precision machinability. This premium material excels in harsh operational environments where reliability and performance directly impact operational efficiency and safety.
Core Composition: Foundation of Superior Performance
Hastelloy C276 (UNS N10276) is a nickel-based superalloy with precisely balanced chemical composition regulated under ASTM B574 standards. The alloy's structure ensures resistance to both oxidizing and reducing environments, with low carbon content minimizing carbide precipitation during welding and high-temperature exposure.
Chemical Composition (wt%)
| Element | Content Range | Function |
|---|---|---|
| Nickel (Ni) | 57.0 min (balance) | Provides base corrosion resistance and structural stability |
| Chromium (Cr) | 14.5 - 16.5 | Enhances oxidation resistance and protects against pitting corrosion |
| Molybdenum (Mo) | 15.0 - 17.0 | Boosts resistance to reducing acids and localized corrosion |
| Iron (Fe) | 4.0 - 7.0 | Improves workability and mechanical stability |
| Tungsten (W) | 3.0 - 4.5 | Increases tensile strength and hardness without sacrificing ductility |
| Cobalt (Co) | 2.5 max | Controlled to maintain alloy purity and performance |
| Carbon (C) | 0.010 max | Prevents carbide precipitation and preserves weld integrity |
| Silicon (Si) | 0.08 max | Minimizes oxidation during processing |
| Manganese (Mn) | 1.0 max | Aids in deoxidation while avoiding brittleness |
Key Properties: Engineered for Industrial Demands
ASTM B574 Hastelloy C276 Bright Bar delivers consistent performance across mechanical strength, corrosion resistance, and thermal stability - critical attributes for industrial machinery applications.
Mechanical Strength & Machinability
With controlled hardness (28-36 HRC) and moderate work-hardening rate, this alloy offers excellent precision machinability for CNC operations. It maintains impressive mechanical properties after machining, suitable for high-precision applications like valve stems, pump impellers, and sensor housings.
Mechanical Properties of Annealed ASTM B574 Hastelloy C276 Bright Bar
| Property | Minimum Value | Unit |
|---|---|---|
| Tensile Strength | 760 | MPa (110 ksi) |
| Yield Strength (0.2% offset) | 355 | MPa (52 ksi) |
| Elongation (in 2 inches) | 40 | % |
| Hardness (Rockwell C) | 28 - 36 | HRC |
| Modulus of Elasticity | 205 | GPa |
Corrosion & Thermal Resistance
Hastelloy C276 provides universal corrosion resistance against aggressive media including sulfuric acid, hydrochloric acid, seawater, chlorine gas, and mixed industrial chemicals. It resists pitting, crevice corrosion, and stress corrosion cracking in high-chloride environments. The alloy maintains performance from cryogenic temperatures up to 1093°C (2000°F).
Industrial Applications: Precision Parts for Critical Systems
- Chemical Processing: Valves, pump shafts, and reactor internals resistant to corrosive feedstocks
- Oil & Gas: Downhole tools and offshore platform components for hydrogen sulfide and saltwater environments
- Power Generation: Flue gas desulfurization system parts and gas turbine bolts for high-temperature applications
- Pharmaceuticals & Food Processing: Sanitary valves and mixing blades meeting strict purity standards
- Marine Engineering: Heat exchangers and condenser tubes for saltwater environments
Compliance & Quality Assurance
ASTM B574 compliance ensures dimensional accuracy (±0.02mm for diameter) and surface quality (bright finish with Ra ≤ 0.8μm). Quality validation includes non-destructive testing and chemical composition verification to meet application-specific requirements.
