Hastelloy Bar and Rod
Hastelloy bar supplied to ASTM B574 - stock, custom sizes, global export.
Our Hastelloy bar and rod collection brings together Hastelloy C-276, C-22, B-2 and B-3 - supplied as round, square and forged bar and rod for corrosive, high-temperature and strength-critical service across chemical, energy, marine and process industries.
Hastelloy is built for the harshest chemical environments. The C-series (C-276, C-22) resist oxidising and reducing acids, chlorides and pitting or crevice corrosion; the B-series (B-2, B-3) are nickel-molybdenum alloys specialised for pure reducing acids such as hydrochloric and sulphuric. All keep useful strength across a broad temperature range.
We supply Hastelloy bar and rod from about 6 mm up to 300 mm diameter, with square, hex and forged shapes available, in the hot-rolled, cold-drawn or forged, in the solution-annealed or age-hardened condition, with ends, surface and tolerances prepared to order. Stock items, cut-to-length and made-to-order dimensions are available, every lot shipped with EN 10204 3.1 mill test certificate and third-party inspection on request.

Applications
Hastelloy bar and rod are machined and forged into components that must hold strength and resist attack in aggressive service:
Chemical & petrochemical
reactors, columns and heat exchangers in aggressive acid service (C-276, C-22).
Flue-gas desulphurisation (FGD)
scrubbers, ducts and dampers (C-22, C-276).
Pharmaceutical & fine chemicals
high-purity process equipment (C-276).
Acid pickling & recovery
hydrochloric and sulphuric acid handling (B-2, B-3).
Pulp & paper / waste treatment
bleaches and corrosive-waste systems (C-276).
Frequently Asked Questions
What diameter range can you supply for Hastelloy bar and rod?
Bar and rod from from about 6 mm up to 300 mm diameter, with square, hex and forged shapes available; both stock and custom sizes are available, cut to length.
What is the minimum order quantity?
Stock sizes from one piece; mill lengths or heavy plate are priced per project. Tell us the grade, size and quantity for a quote.
Do you provide MTC / EN 10204 3.1?
Yes - every lot ships with EN 10204 3.1 mill test certificate, and third-party inspection can be arranged.
What is the typical lead time?
Stock items ship within days; made-to-order material is typically a few weeks depending on size, condition and certification.
Can you supply non-standard sizes or conditions?
Yes - custom sizes, non-standard walls or special tempers are available on request; we also offer cutting and surface preparation.
How do I choose between C-276, C-22 and the B-series?
The C-series (C-276, C-22) cover oxidising and reducing acids, chlorides and pitting; C-22 has broader oxidising-acid resistance. The B-series (B-2, B-3) are for pure reducing acids such as hydrochloric and sulphuric. Match the grade to your dominant corrodent.
