Hastelloy Bars

Hastelloy bars are solid nickel-molybdenum-chromium alloy bars made for highly corrosive and high-temperature environments. They are available in grades such as C276, C22, B2, B3, X, N, C4, and C-2000, with each grade designed for specific chemical and thermal conditions. The molybdenum content, ranging from 15% to 28%, depends on the grade and gives Hastelloy bars exceptional resistance to pitting and crevice corrosion. The key features are outstanding resistance to oxidising and reducing acids, high mechanical strength at elevated temperatures, and reliable performance in environments where standard stainless steels fail. Hastelloy bars are commonly used in chemical processing, pharmaceutical manufacturing, petrochemical plants, and nuclear reactor components.

Hastelloy Bar Price

Hastelloy bar prices vary based on the grade, form, size, surface finish, and order quantity. Understanding these cost elements helps in planning an accurate budget.

Approximate Price Range

The standard grades of hastelloy bars cost between Rs. 2000 and 3500 per kg. The final cost depends on the specific grade selected and the required surface condition.

Factors Affecting Price

• Grade and alloy content: Grades like C22 and C-2000 are more costly than B-series grades. The cost mainly depends on the molybdenum and chromium content in each grade.

• Bar profile and size: Larger cross-sections consume more material per metre. Hex and flat bars may have different rates than round bars due to additional forming steps.

• Surface finish and tolerance: Cold-drawn and polished bars are priced higher than hot-rolled options. Tighter dimensional tolerances require additional machining, increasing the unit cost.

• Order quantity and market conditions: Base prices follow global nickel and molybdenum commodity rates. Confirm current Hastelloy bar pricing per kilogram before placing bulk orders, as rates keep on changing according to market conditions.

How To Choose The Right Hastelloy Bar Supplier And Manufacturer?

Selecting the right hastelloy bars supplier directly affects material quality, delivery time, and total project cost. Evaluate vendors on these 4 criteria before placing any purchase order.

Selecting The Right Supplier And Manufacturer:

Make sure the supplier has Hastelloy bars in the required grade, shape, and size. Not all suppliers offer every variant or custom lengths, so check their capability and stock before sending an RFQ.

Technical Considerations:

Match the Hastelloy grade to the service conditions. C276 is suitable for hydrochloric and sulfuric acid, while Hastelloy X is better for high-temperature oxidation. Always request a Material Test Certificate (MTC) to check composition and properties. Ensure the bars meet ASTM B335, B574, or B572 standards. Custom sizes usually take 6–10 weeks, so check stock early.

Evaluating Supplier Credibility:

A reliable Hastelloy bar supplier must hold at least ISO 9001 certification. Each batch must carry a heat number traceable to the originating mill. This traceability is critical for quality audits in regulated industries such as chemical processing, oil and gas, and nuclear power.

Procurement Strategy:

Send a clear RFQ that includes the grade, UNS number, profile type, size, surface finish, governing standard, and order quantity. At least compare 3 supplier proposals based on price, lead time, MTC availability, and minimum order quantities. For bulk orders, schedule a pre-dispatch inspection (PDI) or third-party inspection (TPI) at the supplier's facility.
