Shanghai Yanxin Metal Materials Co., Ltd. has established a full-cycle quality management system certified to ISO 9001:2015, covering raw material incoming inspection, process control, and finished product verification. Each production step is subject to mandatory quality checks with full traceability.

Our in-house laboratory is equipped with advanced testing equipment to perform:

• Quantitative chemical composition analysis

• Mechanical property testing (tensile, impact, hardness)

• Metallographic examination (grain size, inclusion content)

• Non-destructive testing (ultrasonic testing UT, dye penetrant testing PT)

Every shipment includes a material test certificate (MTC) in accordance with EN 10204 3.1. For additional verification, we can coordinate independent testing by internationally recognized bodies including SGS and Shanghai Research Institute of Materials (SRIM).
