Product Overview
Hastelloy wire mesh is a metal mesh product made from ultra-low-carbon nickel‑based corrosion‑resistant alloys – Hastelloy. Hastelloy is a commercial grade nickel‑based corrosion‑resistant alloy produced by Hastelloy International, Inc., and is mainly divided into nickel‑molybdenum alloys and nickel‑chromium‑molybdenum alloys.
With excellent corrosion resistance, high‑temperature performance and long‑term thermal stability, Hastelloy wire mesh is widely used in harsh industrial environments such as agricultural chemicals, nuclear facilities and biopharmaceuticals. As one of the most corrosion‑resistant materials among modern metals, Hastelloy wire mesh is an ideal choice for handling highly corrosive media.
Core Properties & Features
Excellent Corrosion Resistance
Hastelloy wire mesh is one of the most corrosion‑resistant materials among modern metals. It remains stable in various harsh corrosive environments and offers excellent resistance to:
- Strong corrosive acids: hydrochloric, sulfuric, phosphoric acids, etc.
- Oxidizing media: wet chlorine, various oxidizing chlorides
- Salt solutions: chloride salt solutions, oxidizing salts
- Organic acids: acetic acid, formic acid, etc.
- Chloride ion corrosion: One of the few materials resistant to wet chlorine, hypochlorite and chlorine dioxide solutions
Excellent High‑Temperature Performance
Hastelloy wire mesh has outstanding high‑temperature resistance, allowing long‑term stable operation at elevated temperatures without significant deformation or softening. C‑276 mesh can withstand up to 400℃ with a tensile strength of 780MPa; some grades (e.g., Hastelloy G) can be used continuously at 600℃ and intermittently up to 800℃.
Resistance to Stress Corrosion Cracking
When subjected to combined stress and corrosion, Hastelloy wire mesh is not prone to cracking, ensuring structural integrity and reliability.
High Strength & Mechanical Properties
It has high tensile and yield strength, performing well under pressure and load. For example, annealed Hastelloy C22 has tensile strength ≥ 690 MPa and yield strength ≥ 283 MPa.
Good Workability
Despite its high strength and corrosion resistance, Hastelloy wire mesh can be formed and manufactured using various processing methods, into different mesh counts, shapes and sizes.
