Xurui: Comprehensive Quality Assurance
We have implemented a comprehensive quality management system that oversees the entire production process, from raw material inspection and mechanical testing to metallographic analysis and non-destructive testing. Our factory is ISO 9001:2015 certified, and products are accompanied by Material Test Certificates (MTC) and inspection reports from internationally recognized institutions. Every batch of material is fully traceable, with third-party inspection reports available upon request.
Quality Inspection Throughout the Entire Production Cycle
To ensure consistent quality and reliability in every batch of special steel products, we conduct rigorous inspections from raw materials to pre-shipment.
Raw Material Chemical Composition Testing
Direct-reading spectrometers are used to verify key elements, including carbon, silicon, and manganese, in steel billets. This ensures compliance with international and domestic standards such as ASTM and GB, and guarantees material quality from the very beginning.

In-Process Dimensional Inspection
Precision measuring tools, including micrometers and vernier calipers, continuously monitor key dimensions such as diameter, wall thickness, and length during manufacturing to ensure that dimensional tolerances remain consistent and under control.

Post-Heat-Treatment Hardness Testing
The hardness of heat-treated products is measured using a Rockwell hardness tester. For example, 60Si2Mn spring steel must reach 42–48 HRC to ensure the product meets the required mechanical performance.

Pre-Shipment Surface Quality Inspection
Before packaging, manual inspection is combined with machine vision to thoroughly check for surface defects, including oxide scale, cracks, and scratches, ensuring that all products are delivered with flawless appearance and reliable quality.
Quality Certifications
Xurui holds ISO 9001 certification, and certain products are CE certified. In addition, material testing certificates have been issued by internationally recognized organizations such as SGS and BV, demonstrating our compliance with international quality standards.
