Poor quality stainless steel kitchenware often uses non food grade materials, and the proportion of elements such as manganese, chromium, and nickel is not up to standard. Long term use can bring multiple health and usage risks.
These kitchen utensils have excessive manganese content, extremely low nickel content, and extremely poor corrosion resistance. When exposed to seasonings such as salt, vinegar, soy sauce, or subjected to high temperature heating and repeated scrubbing, harmful substances such as manganese, chromium, and lead are easily precipitated. Long term excessive intake of manganese can damage the nervous system, causing dizziness, memory loss, emotional instability, and other problems; Hexavalent chromium has potential carcinogenic risks and can also irritate the skin and respiratory tract.
At the same time, inferior stainless steel is prone to rusting, peeling, and flaking. Rust and metal debris mixed into food can stimulate the gastrointestinal tract, causing acute discomfort such as nausea, abdominal pain, and diarrhea. In the long run, it can also increase the metabolic burden on the liver and kidneys. Its material strength is poor, the cookware is prone to deformation, the pot bottom cracks, and there may be leakage, local overheating, and safety hazards such as burns and fires during cooking.
In addition, most of these products do not have formal quality inspection labels and do not meet the national food contact material safety standards. Long term use is equivalent to continuous intake of trace heavy metals, which pose more obvious hazards to the elderly, children, pregnant women and other populations. When purchasing, it is necessary to identify food grade labels and relevant national standard certifications.

The Shandong Weihai Inspection and Quarantine Bureau found that the detection value of "chromium" in the batch of stainless steel steam curtains was 4.0 milligrams per square decimeter, which does not meet the limit requirement of 0.4 milligrams per square decimeter for "chromium" in the national standard "National Food Safety Standard Stainless Steel Products" (GB 9684-2011). Therefore, the safety and health project inspection has been determined as unqualified and has been returned for transportation.
