Incoloy Bars

Incoloy bars are solid nickel-iron-chromium alloys designed to withstand high temperatures and corrosive environments. The most common grades are Incoloy 800, 800H, 800HT, 825, and 925, which are designed for certain chemical and thermal conditions. The chromium percentage ranges between 19.5-23.5%, providing strong oxidation resistance, while the nickel base ensures structural integrity during thermal cycling. These bars offer outstanding resistance to oxidation and carburisation, high tensile strength at high temperatures, and consistent performance in acidic and alkaline conditions. Incoloy bars are used in several industries, such as oil and gas, chemical processing, power generation, and marine engineering.

Incoloy Bar Price

Incoloy bar prices vary according to grade composition, bar profile, dimensional tolerance, and order quantity. Understanding the primary cost elements helps in planning an accurate budget.

Approximate Price Range

Incoloy bars are valued between Rs. 1,200 and Rs. 2,500 per kg for standard grades and profiles. The final rate depends on the specific grade and finish selected.

Factors Affecting Price

• Grade and alloy content: Higher-alloy grades, such as Incoloy 825 and 925, cost more than 800-series alloys, due to nickel, molybdenum, and titanium composition in each grade, which directly affects the raw material costs.

• Bar profile and size: Larger cross-sections require more material per metre. Hex and flat bars may carry slightly different rates than round bars due to additional forming stages.

• Surface finish and tolerance: Cold-drawn and polished bars cost more than hot-rolled options. Tighter dimensional tolerances require additional machining, which increases the unit price.

• Order quantity and market conditions: Base prices move with global nickel and chromium commodity rates. Before placing bulk orders, always check the current Incoloy bar prices per kilogram, as rates keep on changing based on the market conditions.

How To Choose The Right Incoloy Bar Supplier And Manufacturer?

Selecting the right Incoloy bar 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

Confirm the manufacturer supplies Incoloy bars in the exact grade, profile, and size required. Not every facility stocks all Incoloy variants or handles custom bar lengths. Verify production capabilities and available stock before sending an RFQ. We at Metline Industries maintain ready stock across Incoloy 800, 825, and 925 in multiple profiles.

Technical Considerations

Match the grade to the required service conditions, such as Incoloy 825 for high-chloride and acidic environments and 800-series grades for high-temperature oxidation resistance. Request a Material Test Certificate (MTC) to verify the chemical composition and mechanical properties. Bars must meet the ASTM B408 or ASTM B425 specifications, as required. Custom sizes often require 6-10 weeks; check stock availability early.

Evaluating Supplier Credibility

A reliable Incoloy bar supplier must have at least ISO 9001 certification. Each batch must be designated with a heat number that can be traceable to the originating mill. This traceability is critical for quality audits and documentation in regulated industries such as oil and gas, power generation, and chemical processing.

Procurement Strategy

Send a clear RFQ that includes the grade, UNS number, profile type, size, finish, governing standard, and order quantity. Compare at least three supplier proposals based on pricing, lead time, MTC availability, and minimum order quantities. For bulk orders, schedule a pre-dispatch inspection (PDI) or third-party inspection (TPI) at the manufacturing plant.
