Hastelloy C-276 (UNS N10276) Ni-Mo-Cr Super Austenitic Corrosion-Resistant Alloy

Hastelloy C-276 is a Ni-Mo-Cr super austenitic corrosion-resistant alloy. It is one of the most widely used all-around corrosion-resistant alloys. It performs exceptionally well in oxidizing and reducing mixed acids, chloride ion-containing environments, wet hydrogen sulfide, and highly corrosive conditions. It has extremely strong resistance to pitting corrosion, crevice corrosion, and stress corrosion, making it the preferred material for highly corrosive applications such as chemical, marine, environmental protection, and pharmaceutical industries.

Advantages:

Extreme Corrosion Resistance:Exhibits exceptional resistance to hydrochloric acid, sulfuric acid, phosphoric acid, mixed acids, wet chlorine, and hypochlorites.

Resistance to Chloride Ion Corrosion:Far superior resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) compared to stainless steel.

Low Carbon and Low Silicon Content:Extremely low carbon content, resulting in no tendency for intergranular corrosion after welding.

Good Cold and Hot Working and Weldability:Can be rolled, stamped, and bent; excellent weldability.

Wide Range of Applications:Resistant to both oxidizing and reducing environments; good high-temperature strength and toughness.

Disadvantages:

Extremely High Price:High nickel, molybdenum, and tungsten content, leading to expensive raw material costs.

Difficult Machining:Severe work hardening, high viscosity, and prone to tool sticking.

Moderate High-Temperature Strength:Lower high-temperature creep strength than high-temperature alloys such as Inconel 718. Stress-sensitive: Corrosion may still occur at localized stress concentration points, requiring appropriate structural design.

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
