Hastelloy C276 Tube Chromium Nickel Alloy Steel Seamless Tube For Chemical Processing

Hastelloy C-276 Tube is a seamless nickel-molybdenum-chromium alloy tube (UNS N10276 / DIN 2.4819) engineered for extreme corrosion resistance in both oxidizing and reducing environments. It is widely used in chemical processing plants, petrochemical production, pollution-control equipment, pulp and paper applications, and any environment where strong acids, chlorides, or mixed corrosive media are present.

Specifications

• Alloy: Hastelloy C-276 (UNS N10276 / DIN 2.4819)

• Form: Seamless tube (welded tubes may also exist depending on supply)

• Applicable Standards:

  • Seamless tube: ASTM B622 / ASME SB-622

  • Welded tube/pipe: ASTM B619/B775, ASTM B626/B751, ISO 6207, DIN 17751

• Sizes: OD typically from 6.35 mm (0.25") up to several inches

• Wall Thickness: SCH5, SCH10, SCH40, and custom precision sizes

• Condition: Annealed, solution-treated, cold-drawn or bright-annealed as required

Main Features

• Outstanding resistance to both oxidizing and reducing corrosion environments

• Excellent resistance to pitting, crevice corrosion, and chloride stress-corrosion cracking

• Stability and strength at elevated temperatures

• Superior resistance to strong acids including sulfuric, nitric, hydrochloric, and mixed acids

• Excellent weldability with minimal carbide precipitation

• Robust mechanical durability for long service life

• Suitable for extreme chemical processes where stainless steels fail

Our Advantages

• Corrosion in aggressive chemicals
  The high chromium–molybdenum–tungsten chemistry provides exceptional protection against acids, halides, chlorides, and mixed corrosive streams.

• Long-term service life
  The alloy maintains high performance under harsh chemical and thermal exposure, reducing downtime and replacement frequency.

• Weldability without performance loss
  Low carbon levels help ensure corrosion resistance is retained in the as-welded condition without special post-weld heat treatment.

• International compliance
  Products are produced to ASTM B622/ASME SB-622 and can be supplied with EN 10204 material certification for global project requirements.

• Cross-industry suitability
  The broad chemical resistance makes this tube ideal for chemical, petrochemical, marine, power-generation, and environmental systems.
