Hastelloy wire mesh is a premium-grade metal mesh product meticulously crafted by our company, utilizing high-quality Hastelloy alloy wires. Hastelloy is a family of nickel-based superalloys renowned for their exceptional resistance to corrosion, high-temperature strength, and durability in the most extreme industrial environments. Composed primarily of nickel, along with significant amounts of chromium, molybdenum, and other alloying elements (such as tungsten, iron, or cobalt, depending on the grade), Hastelloy wire mesh is engineered to perform reliably in applications where conventional metals and even other stainless steels fail.
Material Characteristics
- Unmatched Corrosion Resistance: Hastelloy alloys exhibit extraordinary resistance to a wide range of aggressive media, including strong acids (sulfuric acid, hydrochloric acid, nitric acid), alkalis, chlorides, and organic compounds. This resistance is attributed to their high nickel content, which provides a stable matrix, and the addition of molybdenum and chromium, which enhance resistance to pitting, crevice corrosion, and general corrosion. Even in highly concentrated or high-temperature corrosive environments, Hastelloy wire mesh maintains its integrity.
- Exceptional High-Temperature Performance: Hastelloy wire mesh retains its mechanical strength and corrosion resistance at elevated temperatures, withstanding continuous operating temperatures up to 1200°C (depending on the specific grade). It resists oxidation, carburization, and sulfidation at high temperatures, making it suitable for use in furnaces, chemical reactors, and exhaust systems exposed to extreme heat.
- Superior Mechanical Strength: The alloy composition of Hastelloy gives the wire mesh high tensile strength, creep resistance, and toughness, even at high temperatures. This allows it to withstand mechanical stress, pressure, and vibration in demanding applications without deformation or failure.
- Good Fabricability: Despite its high strength, Hastelloy wire can be woven into intricate mesh patterns with precise dimensions. It offers good ductility and weldability, enabling customization into various mesh sizes and shapes to meet specific application requirements.
Structural Characteristics
- Precision Weaving for Uniformity: Our Hastelloy wire mesh is produced using advanced weaving techniques, ensuring uniform mesh size, consistent opening distribution, and precise filtration accuracy. The tightly interwoven wires form a stable structure that maintains its shape and performance even under extreme corrosion, temperature, or mechanical stress.
- Enhanced Durability: The combination of superior corrosion resistance, high-temperature stability, and mechanical strength makes Hastelloy wire mesh exceptionally durable. It has a long service life in harsh environments, reducing the need for frequent replacement and lowering maintenance costs.
- Smooth Surface and Low Fouling: The surface of Hastelloy wire mesh is smooth, minimizing the adhesion of contaminants, particles, and corrosion by-products. This simplifies cleaning and maintenance, ensuring the mesh retains its filtration efficiency and performance over time.
- Customizable Specifications: To cater to diverse industrial needs, we offer extensive customization options for Hastelloy wire mesh. This includes varying mesh counts (from fine meshes for precision filtration to coarse meshes for heavy-duty applications), wire diameters, mesh shapes (square, rectangular, etc.), and sheet sizes. Our technical team collaborates with customers to develop tailored solutions that align with their specific application requirements.

Standards & Compliance
Hastelloy wire mesh is woven from Hastelloy C276 nickel-molybdenum-chromium alloy (UNS N10276), complying with ASTM B575. It is one of the most corrosion-resistant alloys available, resisting strong acids including hydrochloric and sulfuric acid, and is the standard choice for FGD scrubbers and chemical processing.
FAQ
What is Hastelloy wire mesh?
Hastelloy wire mesh is woven from Hastelloy C276, a nickel-molybdenum-chromium superalloy (UNS N10276). It offers unmatched resistance to strong acids, chlorides and oxidizing media, far beyond standard stainless steel.
Is Hastelloy C276 resistant to hydrochloric acid?
Yes. Hastelloy C276 is one of the few alloys that resists hydrochloric acid across a wide range of concentrations and temperatures, where stainless steel fails. This makes it the standard for HCl and chlorination processes.
What acids can Hastelloy wire mesh resist?
Hastelloy C276 resists hydrochloric, sulfuric, phosphoric and nitric acids, as well as chlorides, oxidizing media and mixed acid environments. It resists both oxidizing and reducing conditions, unlike most stainless steels.
What is the difference between Hastelloy and stainless steel wire mesh?
Hastelloy C276 resists strong acids (especially hydrochloric acid) and pitting far better than any stainless steel, but costs much more. Choose Hastelloy for aggressive acid and FGD service; choose stainless steel for general corrosion resistance at lower cost.
What is Hastelloy C276 used for?
Hastelloy C276 wire mesh is used in FGD scrubber demisters, acid regeneration plants, chlorine gas scrubbers, TiO2 chlorination reactors, sour gas wells and nuclear fuel reprocessing — wherever strong acids and chlorides are present.
What temperature can Hastelloy wire mesh withstand?
Hastelloy C276 wire mesh retains strength and corrosion resistance at elevated temperatures, with continuous service up to about 1200°C depending on the environment. It resists oxidation, carburization and sulfidation.
