Hastelloy Alloys – Extreme Corrosion Resistance for Aggressive Chemical Environments
Nickel-molybdenum-chromium-based Hastelloy alloys offer unmatched corrosion resistance in both oxidizing and reducing environments. Ideal for chemical plants, pharmaceuticals, and marine systems.
What Is Hastelloy?
Hastelloy® is a trademarked family of nickel-based superalloys developed by Haynes International. These alloys are engineered to resist highly aggressive chemical media, such as:
Hydrochloric acid,Sulfuric acid,Ferric chloride,Sodium hypochlorite,Acetic & phosphoric acids.
Its superior thermal stability, stress corrosion cracking resistance, and pitting resistance make it ideal for extreme conditions where stainless steel or lower alloys fail.
Popular Grades:
C-276 – Most versatile grade for oxidizing/reducing media
C-22 – Higher resistance to oxidizing agents like nitric acid
B-2 / B-3 – Excellent in hydrochloric and non-oxidizing acids
X / G30 / G35 – Niche applications in fertilizer, pickling & heat exchangers

Frequently Asked Questions
Q1: What is the difference between Hastelloy C-276 and C-22?
A:
C-22 offers better resistance to oxidizing agents like nitric acid, while C-276 is the most versatile for both oxidizing and reducing conditions.
Q2: Can Hastelloy withstand hydrochloric acid?
A:
Yes. Grades like B-2 and B-3 are specifically resistant to hydrochloric acid, even in high concentrations.
Q3: Do you support export of pressure vessel certified Hastelloy?
A:
Yes, we provide 3.1 / 3.2 MTC and support EN, ASME code stamping via partners if needed.
Q4: What is the minimum quantity I can order?
A:
MOQ can be as low as 10kg for stock material or 1 piece of cut sheet/bar.
Q5: Is machining Hastelloy difficult?
A:
It requires slow speeds and carbide tools. We offer CNC service with expert parameters for Hastelloy grades.
