Acceptable Quality with Minor Packaging Issues Resolved
Decent product quality for general industrial spring applications, though initial shipment had packaging concerns. We ordered 5 tons of 301 coil in quarter-hard temper (1.0mm thickness, 400mm width) for industrial conveyor belt tensioning springs. Material mechanical properties met ASTM A666 specifications with tensile strength at 785 MPa. However, first delivery arrived with moisture damage on outer wraps due to inadequate VCI paper coverage, affecting approximately 15 meters of coil ends. Supplier immediately arranged replacement of affected material within 5 days and upgraded packaging specification for subsequent shipments at no additional cost. Their responsive customer service and willingness to implement corrective actions demonstrated professional approach. Since packaging improvement, two follow-up orders have arrived in perfect condition. Material performance in our spring winding operations is satisfactory with predictable elastic behavior. Would recommend requesting enhanced packaging specification upfront for humid climate destinations. Overall acceptable supplier once packaging protocols are established.
