Hastelloy Wire Mesh | High-Temp and Corrosion Resistant Alloy Mesh
Hastelloy Wire Mesh | High-Temp and Corrosion Resistant Alloy Mesh
Hastelloy wire mesh is a premium high-performance woven mesh fabricated from nickel-based super corrosion-resistant alloys. Differing from ordinary stainless steel and common alloy meshes, this mesh material integrates exceptional high-temperature stability, comprehensive corrosion resistance and superior anti-oxidation performance, standing out as a core filtering and structural material for extreme industrial working conditions. It can stably operate in severe environments with strong acid, alkali, chloride corrosion and high temperature, and is widely adopted in chemical processing, petroleum refining, nuclear energy facilities, biopharmaceuticals, aerospace engineering and environmental protection industries, serving as a reliable solution for industrial filtration, separation and anti-corrosion protection.
What is Hastelloy Wire Mesh?
Hastelloy wire mesh is customized and woven with high-purity Hastelloy alloy wires. The alloy system is mainly composed of nickel (Ni), chromium (Cr), molybdenum (Mo), and is supplemented with trace elements such as tungsten, titanium, manganese, iron and cobalt. The precise element ratio endows different grades of Hastelloy mesh with targeted environmental adaptability, covering oxidizing, reducing and alternating corrosive environments. Each grade features unique component formulas and performance orientations to meet differentiated industrial demands.
What are the material characteristics of Hastelloy wire mesh?
Different Hastelloy alloy grades have distinct element proportions and applicable scenarios, covering most extreme corrosive working conditions in the industry:
A versatile universal corrosion-resistant grade, containing approximately 57% nickel, 16% molybdenum, 15.5% chromium and 3.75% tungsten. With ultra-low carbon content, it effectively avoids carbide precipitation during processing and use. It delivers excellent resistance to wet chlorine, oxidizing chlorides, chloride salt solutions and pitting/crevice corrosion, and is suitable for complex chemical corrosive environments.
A professional anti-reduction corrosion grade, with about 62% high-purity nickel and 28% molybdenum. It boasts outstanding tolerance to strong reducing acids represented by hydrochloric acid, and maintains stable anti-corrosion performance in high-concentration reducing media, solving the corrosion failure problem of ordinary alloys in pure reducing environments.
A balanced dual-environment resistant grade, consisting of 56% nickel, 22% chromium and 13% molybdenum. It achieves excellent corrosion resistance in both oxidizing and reducing environments, with stronger resistance to mixed acid corrosion and stress corrosion cracking than conventional grades, adapting to variable chemical working conditions.
A high-chromium anti-medium corrosion grade, containing 43% nickel, 29.5% high chromium and 5% molybdenum. It has superior tolerance to halide media, high-concentration sulfuric acid and industrial flue gas corrosives, and is widely used in environmental protection desulfurization and strong acid processing scenarios.
Why choose Hastelloy wire mesh?

What are the differences between Hastelloy wire mesh and other metal meshes?
Hastelloy mesh outperforms common metal meshes in extreme corrosion and high-temperature adaptability, with obvious differentiated positioning.
- VS 316L Stainless Steel
316L only suits weak corrosion and normal temperature, prone to pitting and cracking in strong acid/chloride environments. Hastelloy resists mixed strong corrosion, with 8+ times longer service life in extreme conditions.
- VS Inconel Mesh
Inconel excels in dry high-temperature oxidation resistance but poor in strong acid corrosion. Hastelloy focuses on wet corrosion resistance, especially for hydrochloric acid and mixed acid media.
- VS Titanium Mesh
Titanium works well in nitric acid and seawater but fails in hydrochloric acid and fluorine-containing media. Hastelloy features full-media corrosion resistance for more complex working conditions.
How to Select the Right Hastelloy Wire Mesh?
Follow the medium - temperature - precision - structure 4-step principle to select the optimal specification:
Step 1: Medium Matching
Strong reduction (HCl) → B-2;
Mixed acid/chloride → C-276;
Alternating oxidation-reduction → C-22;
High-sulfur flue gas/halide → G-30.
Step 2: Temperature Adaptation
≤200℃ – all grades available;
200–425℃ – prefer C-22 & C-276 for stable high-temperature performance.
Step 3: Filtration Precision
Coarse protection – 1-40 mesh;
Conventional filtration – 40-100 mesh;
Fine/sterile filtration – 100-200 mesh.
Step 4: Weaving Type
High precision & uniform pores – plain weave;
High pressure/impact resistance – twill weave.
