Quality Services for High-Performance Metal Materials
Sunxin provides quality services for high-performance metal material projects, helping customers verify material consistency, traceability, chemical composition, mechanical properties, internal quality, and heat treatment condition.
Our quality support covers stainless steel, titanium and titanium alloys, cobalt-based alloys, cobalt-chromium-molybdenum alloys, tantalum materials, and Nitinol / NiTi alloy used in medical, aerospace, mechanical engineering, and industrial applications.

Quality Support for Reliable Material Supply
For high-performance metallic materials, quality assurance should not be limited to final inspection, but should extend throughout the entire supply chain. Depending on project requirements, customers may require process control, batch consistency management, furnace number tracking, third-party testing and inspection data to confirm that the supplied materials meet the specified requirements.
Our quality services support a more reliable supply of materials through process management, traceability control, testing coordination and verification of key material properties. This helps customers to strengthen their confidence in material consistency and reduce quality-related risks during procurement, production and end-use applications.

ERP System Management, Full Process Traceability, and Batch Stability
Through ERP management and end-to-end traceability, Sunxin can help clients manage order information, batch records, inspection data, packaging details and delivery status with greater clarity throughout the material supply process. This helps to reduce common procurement issues such as unclear order progress, missing batch information, inconsistent documentation, and difficulties in matching materials with inspection or delivery records.
For clients with recurring orders or long-term project requirements, batch consistency is particularly important. We can assist clients in managing batch information, quality records and supply coordination more systematically, thereby maintaining more consistent material performance, streamlining incoming goods inspection processes, and reducing quality and documentation management risks during production.


Furnace Number Management
Heat / furnace number management is an important part of material traceability and batch consistency control. It helps link each material batch with chemical composition, process records, inspection results, heat treatment conditions, and related quality information.
For customers who require clearer batch control and material identification, Sunxin helps maintain organized furnace number records throughout the supply process. This makes it easier to match supplied materials with quality documents, improve batch-to-batch consistency, and support traceability during incoming inspection, production, and long-term material management.
Third-Party Testing Support
When clients require independent verification of material quality, Sunxin can assist in arranging third-party testing support. This service is suitable for projects requiring enhanced testing credibility, meeting client-specified testing requirements, providing external test reports, or addressing more stringent document audits.
Sunxin can assist in coordinating the relevant test reports based on the required test items, project specifications, applicable standards and client requirements. This helps clients to more easily verify material compliance, supports internal quality approval processes, and reduces uncertainty prior to production or final application.


Chemical Composition Analysis
Chemical composition analysis helps you verify that the supplied materials comply with the specified grades, standards and specifications, thereby reducing the risk of using the wrong materials, inconsistencies in batch composition, or materials failing to meet project requirements.
Sunxin can assist in arranging chemical composition testing in accordance with your material standards, project specifications and test requirements. For certain materials, we can also discuss additional testing for elements such as oxygen, nitrogen and hydrogen, if required.
Mechanical Property Testing
Mechanical property testing can help you verify whether the supplied materials meet the strength, hardness, ductility and other performance requirements of your application.
Sunxin can assist in arranging relevant tests prior to production or end use, helping you minimise the risk of material mismatches, inconsistent performance or quality issues. This service is suitable for projects in the medical, aerospace, mechanical engineering and industrial sectors.

UT Flaw Detection
UT testing, also known as ultrasonic testing, can be arranged according to the type and dimensions of the material in question to help identify internal defects and verify the internal quality of the material.
When you require additional verification of internal quality, Sunxin can assist in arranging ultrasonic testing to help you mitigate the risks associated with hidden defects prior to machining, production or end use. This service is suitable for projects in the medical, aerospace, mechanical engineering and industrial sectors.
Microstructure Examination
Microstructural analysis can be used to assess a material’s grain structure, inclusions, and condition, as well as the effects of machining or heat treatment on its microstructure. This analysis is particularly useful when you need to confirm the stability of a material prior to machining, production or final application.
Depending on project requirements, Sunxin can assist in arranging metallographic microscopy or electron microscopy testing to help you gain a clearer understanding of the internal microstructure of the supplied materials, thereby reducing the risks associated with performance instability or potential quality issues.


Heat Treatment Verification
Heat treatment verification helps to confirm whether the material has achieved the required delivery condition, hardness, microstructure and relevant performance requirements following heat treatment.
This verification is particularly important for precipitation-hardening stainless steels, martensitic stainless steels, certain titanium alloys, cobalt-based alloys and other special materials where the heat treatment condition directly affects the final performance.
Sunxin can assist in arranging heat treatment verification prior to machining, production or end use, helping you to minimise the risks of incorrect delivery conditions, inconsistent hardness or mismatched material properties.
