Hastelloy C22 strip is a versatile, corrosion-resistant nickel-chromium-molybdenum-tungsten alloy designed to perform in some of the most demanding environments. Its exceptional resistance to both oxidizing and reducing agents makes it a preferred material in industries that require reliability, purity, and long-term stability—such as pharmaceutical manufacturing and marine engineering.

Material Overview

Hastelloy C22 (UNS N06022) is engineered to resist:

Pitting

Crevice corrosion

Stress corrosion cracking

A wide range of acidic and chloride-rich environments

Its high molybdenum and chromium content, combined with a small amount of tungsten, gives C22 strip exceptional corrosion resistance across a wide range of media, including mixed acid environments.

In strip form, Hastelloy C22 is available in various thicknesses and widths, offering high flexibility for manufacturers requiring precision and uniformity in component design.

Applications in the Pharmaceutical Industry

In the pharmaceutical sector, equipment must maintain extreme cleanliness, resist corrosion from harsh cleaning agents, and prevent contamination of sensitive products. Hastelloy C22 strip is ideal for manufacturing:

Reactors and mixing vessels

Storage tanks and piping

Fluid handling systems

Clean-in-place (CIP) systems

Sterilization units

Its smooth surface finish and corrosion resistance ensure compliance with FDA and GMP standards, helping to maintain product purity and operational integrity.

Applications in Marine Environments

In marine engineering, materials must perform under continuous exposure to saltwater, biofouling, and variable temperatures. Hastelloy C22 strip is used in:

Seawater cooling systems

Pump and valve components

Subsea umbilicals and risers

Offshore chemical injection systems

Heat exchangers and condensers in ships and oil platforms

Its durability in both stagnant and flowing seawater environments makes it an excellent alternative to traditional marine alloys that may suffer from premature corrosion or failure.

Meeting Industry Needs

Key user requirements addressed by Hastelloy C22 strip include:

Long-term resistance to corrosion in acidic and saline conditions

Excellent weldability and formability for complex component fabrication

Low maintenance and long service life, reducing total ownership cost

Compliance with industry standards, including ASTM, ASME, and NACE
