Acceptable Quality with Minor Packaging Issues Resolved
Decent product overall with some initial concerns on our 4-ton order of 316 stainless steel sheet (4mm thickness, 1500mm width). Material quality met ASTM A240 specifications with proper chemical composition and mechanical properties verified by our receiving inspection. However, 2 sheets arrived with surface scratches from inadequate interleaving protection during ocean freight transit. We documented the damage with photos and contacted supplier within 24 hours. Their response was professional - replacement sheets shipped via air freight at their expense and arrived within 6 days, minimizing our production delay to acceptable levels. They also upgraded packaging specifications for future orders with thicker protective film and improved crating. Would suggest implementing better quality control on packaging procedures before shipment. Material performance in our sulfuric acid processing application has been satisfactory. Will consider future orders given their responsive problem resolution, but expect improved packaging standards.
