Ni-Cr Alloy Wear-Resistant Ring X-750/N07750 High Temperature Superalloy

 

Inconel X-750 Wear-Resistant Ring | High-Performance Solution for Extreme Wear & Corrosion Environments

Inconel X-750 wear-resistant rings are premium sealing and load-bearing components engineered for harsh industrial applications combining high temperature, severe wear, and aggressive chemical exposure. As a precipitation-hardened nickel-chromium superalloy (UNS N07750 / W-Nr. 2.4669 / GH4145), X-750 delivers exceptional wear resistance through a unique combination of high hardness, precipitation strengthening, and corrosion resistance, outperforming conventional stainless steels and even some cobalt-based alloys in critical operating conditions.

 

Core Material & Wear Resistance Mechanism

Category

Details

Alloy Designation

Customization & Quality Assurance

We offer full-range customization options to meet your specific wear resistance requirements:

  1. Size Customization: Outer diameter, inner diameter, thickness, and profile can be tailored to your equipment drawings

  2. Surface Enhancement: Optional wear-resistant coatings (plasma nitriding, DLC, etc.) to further improve service life

  3. Heat Treatment Optimization: Custom aging cycles for specific operating temperatures and load conditions

  4. Quality Documentation: Complete Material Test Reports (MTR), hardness test results, grain size analysis, and non-destructive testing (NDT) records

All Inconel X-750 wear rings undergo rigorous quality control including ultrasonic testing, magnetic particle inspection, and dimensional verification to ensure compliance with aerospace and industrial standards.

 

Why Choose Inconel X-750 Over Other Wear-Resistant Alloys?

  1. Superior Corrosion-Wear Synergy: Unlike conventional wear-resistant steels, X-750 maintains excellent corrosion resistance in aggressive environments, preventing "corrosion-assisted wear" failure

  2. High-Temperature Stability: Retains wear resistance and mechanical properties at temperatures where standard wear materials soften and fail

  3. Long-Term Cost Efficiency: Extended service life (5-10x longer than stainless steel) reduces maintenance frequency and downtime costs

  4. Versatile Performance: Suitable for both dry and lubricated wear applications, as well as static and dynamic sealing scenarios

DINGSCO Complete Production Chain:

SMELTING → FORGING → HEAT TREATMENT → MACHINING → HOT EXTRUSION

①Foundational Assurance in Smelting and Forging:

VIM furnaces ensure alloy purity; ESR furnaces further optimize internal structure. Forging yields diverse billets, laying a defect-free foundation for downstream processing and controlling material properties at the source.

②Precision Control in Intermediate Processing:

Heat treatment is customized for alloys. CNC machining enables high-precision forming, yielding semi-finished parts to ensure pre-extrusion billets meet forming specs.

③Synergistic Value of Hot Extrusion with Full Process:

The new hot extrusion press is part of an integrated system: High-purity alloys (VIM/ESR), dense forging microstructures, and heat-treated performance collectively enable stable extrusion of hard-to-form alloys. Produced complex components: seamless pipes, profiles; material utilization up 15-20%. Full-process efficiency cuts standard model lead times to 5-10 days.
