Frequently Asked Questions

1. Is Hastelloy C276 better than stainless steel 316L?
For most general corrosive service, 316L is a proven, cost-effective option. Hastelloy C276 pulls ahead specifically in chloride-rich, wet chlorine, or mixed oxidizing/reducing environments where 316L is prone to pitting and crevice corrosion.
2. What is the maximum temperature for Hastelloy C276 fittings?
Hastelloy C276 maintains good mechanical strength and oxidation resistance at elevated temperatures used in reactors and heat exchangers; exact limits depend on the specific pressure rating and code (ASME/ASTM) governing your project, so confirm with Mcneil Alloys’ engineering team for your exact service conditions.
3. Are Hastelloy C276 fittings available seamless and welded?
Yes. Mcneil Alloys supplies both seamless and welded construction to ASTM B366 / ASME SB366, so you can match the fitting type to your line’s pressure class and code requirements.
