Inconel Bar Ideal Material For High Stress High Temperature Applications

ISO9001 & SGS Certified | Est. 2002 | 12,000 m² Factory | 8.0–200mm | 3–7 Day Dispatch

Inconel bars from Changzhou DLX Alloy Co., Ltd. are engineered to perform where conventional materials fail — under extreme mechanical stress at sustained elevated temperatures. Manufactured through a combined forging and drawing process with precisely controlled heat treatment for optimized grain structure, our Inconel bars deliver the creep resistance, fatigue strength, and microstructural stability demanded by gas turbine shafts, aerospace structural components, downhole drilling tools, and high-temperature fasteners. We supply 7 Inconel grades in round bar, flat bar, and hexagonal forms from 8.0 to 200 mm diameter — all with full EN 10204 3.1 MTC traceability on every shipment.

Not sure which grade? Share your maximum operating temperature, sustained stress level, and environmental media — our metallurgical team recommends the optimal grade and heat treatment condition within 24 hours.

• Forged + drawn for grain structure integrity — Combined forging and precision drawing with optimized heat treatment develops uniform fine-grain microstructure. Demonstrably better creep resistance and fatigue life than bar produced by rolling alone. Critical when your component sees sustained stress at red heat.
• Full range: 8.0–200mm diameter — From small-diameter precision bars for aerospace fasteners that must not fail, to large forged bars for gas turbine shafts carrying tonnes of rotating mass. One supplier, one quality system, full traceability across your entire size range.
• Age-hardened grades ready to machine — Inconel 718 and X750 available in solution-annealed condition (machine, then age harden) or fully precipitation-hardened condition (finish machine only). We match supply condition to your manufacturing route and final property targets.
• Full heat-to-bar traceability — Every bar linked to original heat number. EN 10204 3.1 MTC with chemistry, mechanical properties, and grain size included as standard. When your customer's inspector audits your material certs, there are no gaps in the chain.
• Integrated production — melt to finished bar — Melting, forging, rolling, drawing, heat treatment, straightening, and UT testing all under one roof. No quality gaps from outsourced steps. No one else's process variation shows up in your material properties.
• Ultrasonic tested as standard — UT per ASTM A388 / AMS 2301 on bars for critical rotating and load-bearing applications. Surface and internal integrity verified before your bar leaves our facility.

Changzhou DLX Alloy Co., Ltd. was founded in 2002 with a single focus: nickel-based specialty alloys. We are not a general steel service center stocking whatever sells — every forging press, drawing bench, and heat treatment furnace is configured for nickel alloy manufacturing.

• 12,000 m² dedicated facility — integrated melting, forging, rolling, drawing, heat treatment, straightening, and NDT testing under one roof. Bars are produced from ingot to finished product, not traded from unknown sources.
• 1,200-ton annual capacity — automated rolling and drawing lines improving throughput by ~25% over conventional equipment, with in-process quality gates at every production stage.
• 8.0–200mm full diameter range — from precision small-diameter bar for machining blanks to large forged bar for heavy shafts. One supplier covers your project bill of materials.
• Five product forms — bar, strip, tube, plate, and wire — integrated supply for customers sourcing multiple material forms from a single qualified vendor.
• ISO9001 quality management with multi-point traceability; SGS-accredited with BV and TÜV third-party inspection available.

Note: Inconel 718 and X750 values are for age-hardened condition. Solution-annealed and other heat treatment conditions available on request.

Third-party inspection by SGS, BV, or TÜV available upon request. All shipments fully documented and traceable to heat number.

For sustained stress above 700°C, Inconel X750 (gamma-prime strengthened, best relaxation resistance) and Inconel 617 (outstanding creep rupture strength) are your primary options. For high stress below 700°C, Inconel 718 delivers the highest tensile and fatigue strength. Share your stress, temperature, and cycle profile — we recommend within 24 hours.

Yes. Inconel 718 and X750 are available in solution-annealed condition (machine to near-net shape, then age harden in-house) or fully age-hardened condition for finish machining only. Specify your target hardness range or AMS specification.

Yes. UT per ASTM A388 / AMS 2301 is available as standard for bars intended for rotating shafts, turbine discs, and other safety-critical components. We can test to your specific acceptance criteria and include full UT reports with your MTC.

MOQ is negotiated per grade, diameter, and specification. We support trial quantities for first-time buyers to validate quality and machinability before committing to production volumes.

Every shipment includes EN 10204 3.1 MTC with full chemical composition and mechanical properties, UT test reports (if specified), dimensional inspection report, certificate of conformance, and packing list. All documentation traceable to original heat number.
