What is Hastelloy B2 Wire Mesh?
Hastelloy B2 wire mesh is a high-performance woven alloy mesh made primarily from nickel and molybdenum, engineered to withstand strong acidic environments, including hydrochloric acid, sulfuric acid, and acetic acid. It is trusted in industries where standard stainless steel would corrode rapidly.
Why It’s Used in Acidic & Aggressive Environments
Hastelloy B2 is known for its resistance to pitting, stress corrosion cracking, and crevice corrosion. It remains stable in reducing media and aggressive chemical conditions, making it ideal for filtration, separation, and containment in:
- Chemical processing plants
- Pickling equipment and acid recovery systems
- Heat exchangers exposed to acids
- Nuclear and aerospace chemical components
When your process involves high-acid concentration, fluctuating pH, or oxidizing agents, stainless steel often fails — but Hastelloy B2 thrives.
Key Trends, Challenges & Common Buyer Questions
🔼 Market Trends:
- Shift to nickel-based alloys in acid filtration and storage systems
- Replacement of PTFE-based synthetic filters with metallic woven mesh for high-temp, high-acid processes
- Use of Hastelloy B2 filters in pharma, biofuels, and semiconductor sectors
❓ Common Queries:
- Is Hastelloy B2 better than stainless steel for acid resistance?
- Can it handle hydrochloric acid at high temperatures?
- What mesh sizes are available for fine filtration in chemical lines?
- Is it weldable or formable into baskets and filter cartridges?

How Hastelloy B2 Mesh Solves Acid-Handling Challenges
Standard stainless steel begins to degrade when exposed to strong acids. Hastelloy B2 wire mesh, however, is purpose-built for such corrosive conditions. At IG Wire Screen Co., we supply woven Hastelloy B2 mesh that delivers:
- Superior resistance to hydrochloric, sulfuric, and acetic acids
- Structural integrity at high temperatures
- Zero pitting or stress cracking in reducing environments
- High strength-to-weight ratio with fine filtration capabilities
It’s the ideal solution for filtration, venting, containment, and chemical protection in extreme environments where failure is not an option.
