Manufacturing Process & Quality Control

High-Quality Melting & Bar Forming: Utilizing advanced vacuum melting (VIM/VAR/ESR) technologies to produce high-purity nickel-based alloy ingots. Subsequently, through rigorously controlled forging, hot rolling, and precision cold drawing and/or cold rolling processes, we ensure the nickel-based alloy bar/rod's density, uniformity, excellent surface finish, and mechanical properties.

Precision Heat Treatment: Implementing precise solution annealing and/or aging treatments to relieve processing stress, optimize grain structure, and ensure the material's creep strength, oxidation resistance, toughness, and ultimate service performance.

High-Precision Machining: Offering turning, grinding, polishing, and other machining services to ensure precise bar dimensions and surface finish, meeting high-precision application demands.

Rigorous Quality Testing (INSPECTIONS):

Raw Material Inspection: Strict chemical composition analysis (ICP-OES, GDMS, etc.), including precise control over trace impurities and alloy element content.

Internal Flaw Detection: Ultrasonic Testing (UT) and/or Eddy Current Testing (ET) are performed on finished bars to ensure the absence of internal cracks, inclusions, porosity, and other defects.

Geometric Dimensions & Visual Inspection: Precise measurement of diameter, length, straightness, ovality, and high-precision visual and automated inspection for surface defects (e.g., scratches, indentations).

Mechanical Properties Testing: Tensile Test (Elongation, Yield Strength, Tensile Strength, including high-temperature tensile), Hardness Test, Impact Test, Bend Test, Creep Test (as required), Fatigue Test (as required).

Corrosion Testing: Corrosion tests in specific corrosive media (e.g., ASTM G28, G48, G35, G36) are performed to verify durability in harsh chemical environments.

Metallographic Analysis: Evaluation of grain size and microstructure to ensure conformity with standards and final application requirements.

Traceability: Comprehensive material reports are provided, ensuring complete traceability from raw material to final bar/rod, with support for independent third-party certification.
