Raw Materials & Supply Chain
01
The primary raw material used for our stamped components is heat-treated steel strip.
02
Full material traceability from the finished component back to the original steel heat and raw material source.
✓
Each incoming steel strip is identified by a unique Coil No. The corresponding Material Certificate records key material information, including the material grade, chemical composition, mechanical properties, and Heat No.
✓
The Heat No. serves as the key link between the supplied steel strip and the original steelmaking batch / billet information.
