Material Selection Guide

When to consider Inconel 602CA

This guide helps buyers connect service conditions with the typical advantage of Alloy 625. Final selection should consider medium concentration, temperature, pressure, fabrication, availability and budget.

Service Requirement Why Alloy 602CA Helps Common Product Form Buyer Note
Continuous high-temperature service High carbon content and controlled carbide formation provide excellent creep strength, especially above 1000 °C. Plate, sheet, bar, tube and forgings Confirm operating stress, design life, atmosphere and maximum metal temperature.
Cyclic oxidation up to approximately 1200 °C Chromium, aluminum and yttrium promote a dense and adherent protective oxide layer that resists spalling during thermal cycling. Sheet, plate, strip, tube and fabricated furnace parts Specify heating and cooling rates, cycle frequency and furnace atmosphere.
Carburizing atmospheres The alloy provides strong resistance to carbon penetration and carburization in industrial furnace and petrochemical service. Radiant tube, furnace muffle, plate, bar and fittings Confirm carbon activity, temperature, pressure and gas composition.
Metal dusting conditions The protective alumina-rich scale helps reduce metal dusting attack in carbon-rich process gases. Pipe, tube, fittings and reformer components Review gas composition, temperature range and expected shutdown conditions.
Oxidizing and chlorinating media High chromium content supports resistance in selected oxidizing and oxidizing-chlorinating high-temperature environments. Plate, sheet, pipe, tube and fabricated assemblies Confirm chlorine level, oxygen potential, deposits and operating temperature.
Furnace and heat-treatment equipment Excellent scale adhesion and creep resistance support long service life in furnace muffles, radiant tubes, rollers and fixtures. Sheet, plate, tube, bar, forgings and fasteners Specify mechanical load, support spacing, thermal cycling and dimensional tolerances.
Welded high-temperature fabrication The alloy can be welded with matching ERNiCrFe-12 filler using controlled heat input and suitable nickel-alloy procedures. Plate, sheet, pipe, tube and fittings Control cleanliness and interpass temperature; service at 600-750 °C may require stabilization annealing.

FAQ

Inconel 602CA questions from buyers

Find practical answers about procurement, standards, fabrication and industrial applications.

Inconel 602CA is mainly used for radiant tubes, furnace muffles, rotary and shaft furnaces, kiln rollers, petrochemical reformers, hydrogen and synthesis-gas equipment, combustion components, automotive exhaust systems and other parts exposed to severe high-temperature oxidation or carburization.

Yes. UNS N06025 is the standardized UNS designation commonly associated with Alloy 602 CA. The material may also be identified as Inconel 602CA, W.Nr. 2.4633, NiCr25FeAlY or Nicrofer 6025 HT.

Alloy 602CA provides excellent oxidation resistance at temperatures up to approximately 1200 °C or 2192 °F. The practical design temperature depends on mechanical stress, furnace atmosphere, thermal cycling, component geometry and the required service life.

Alloy 602CA contains higher chromium, controlled high carbon and microalloying additions of yttrium and zirconium. These additions provide higher creep strength and improved cyclic oxidation, carburization and metal-dusting resistance in severe high-temperature service.

YSN128 can quote plate, sheet, strip, round bar, rod, wire, seamless or welded pipe and tube, forgings, flanges, fittings, fasteners and matching welding wire. Large dimensions, fabricated components, machining allowance and drawing-based supply can be discussed.

Common standards include ASTM B168 for plate, sheet and strip, ASTM B166 for rod, bar and wire, ASTM B167 for seamless pipe and tube, ASTM B516 and ASTM B517 for welded products, ASTM B564 for forgings and flanges, EN 10302, VdTÜV material data sheet 540 and the corresponding ASME specifications.

Yes. Alloy 602CA can be welded using suitable nickel-alloy procedures and matching filler metal such as AWS A5.14 ERNiCrFe-12 or EN ISO 18274 S Ni 6025. Joint surfaces must be clean, heat input should be controlled and the interpass temperature should generally remain below 120 °C.

Preheating is normally not required. However, welded components intended for prolonged service between approximately 600 and 750 °C may require stabilization annealing. The final heat-treatment procedure should be confirmed against the component design and project specification.

Yes. EN10204 3.1 material certificates can be supplied on request, including heat number, chemical composition, mechanical test results, heat-treatment condition and applicable inspection records.

Please send the grade or UNS number, product form, dimensions, quantity, applicable standard, delivery condition, service temperature, furnace or process atmosphere, certificate requirements and destination. Drawings, welding requirements and additional inspection requirements are also welcome.
