Hastelloy Nickel-Moly Pipes

The world's most versatile corrosion-resistant alloys � Engineered for extreme chemical processing and aggressive environments.

Advanced Hastelloy Piping Solutions

Steel Emporium is a leading stockist and manufacturer of Hastelloy Pipes and Tubes. Hastelloy is a nickel-molybdenum-chromium superalloy with an addition of tungsten, designed to have excellent corrosion resistance in a wide range of severe environments. It is widely considered the most versatile corrosion-resistant alloy available today.

These pipes are particularly resistant to pitting, crevice corrosion, and stress corrosion cracking. They are used in the most demanding applications such as chemical processing, pollution control, pulp and paper production, and waste treatment. Our range includes the legendary Hastelloy C276 and the enhanced Hastelloy C22, both available in seamless and welded forms with 100% traceability.

Technical Advantages

Universal Resistance

Outstanding resistance to a wide variety of chemical process environments, including strong oxidizers like wet chlorine and ferric chlorides.

Localized Corrosion Protection

High molybdenum and chromium content provides exceptional resistance to pitting and crevice corrosion in chloride-rich media.

Excellent Weldability

Low carbon content minimizes carbide precipitation during welding, maintaining the alloy's corrosion resistance in the "as-welded" state.

High Temp Stability

Maintains structural integrity and resistance to oxidation even under extreme thermal stress and high-pressure cycles.

Premium Hastelloy Grades

Hastelloy C276 (UNS N10276)

The standard "workhorse" grade. Known for its resistance to both oxidizing and reducing media, especially in aggressive chemical reactors.

View Specifications
Hastelloy C22 (UNS N06022)

Next-generation alloy with higher chromium. Offers significantly better resistance to pitting and intergranular attack in wet chlorine environments.

Frequently Asked Questions

Hastelloy superalloys contain much higher levels of Nickel and Molybdenum than stainless steel, making them immune to many acids and high-chloride environments where 304 or 316 would fail immediately.

Hastelloy C22 has higher chromium content (22%) than C276 (16%), which provides better protection in oxidizing environments like wet chlorine and nitric acid.

Yes, C276 is one of the few alloys that can withstand hydrochloric acid across a wide range of temperatures and concentrations.

No, Hastelloy C276 and C22 are non-magnetic in all conditions, making them ideal for specialized electronic and precision instrumentation.

The primary standards are ASTM B622 (Seamless Pipe and Tube) and ASTM B619 / B626 (Welded Pipe and Tube).
