Perfect quality management system
In 2013, it passed the ISO9001 international quality management system certification. Wantai Special Steel carefully studied the ISO9001 international quality management system, and built its own quality management system based on the successful experience of Shagang and Baosteel:
Every level is checked, and the current quality inspection of Wantai Special Steel has been checked at all levels to ensure quality;
Monitoring measures, establishing company supervision, internal self-supervision and other tripartite supervision mechanisms;
Formulate inspection specifications and inspection procedures, currently mainly quoting national standards and specifications;
Product quality spot check and inspection: Strengthen product quality inspection within the company; at the same time, the company often goes to Shanghai Institute of Materials Research, Beijing Academy of Coal Research and other national authoritative institutions for comparative spot check and inspection.
The company's laboratory has passed the CNAS national laboratory standard certification.
