Excessive manganese in stainless steel is harmful to human health

　　The researchers believe that nickel is a scarce and valuable resource, and use partial manganese to replace nickel is the development direction of the stainless steel industry, in line with the conservation of resources, energy saving and environmental protection trend. Under the case of not affecting the use of performance, the development of resource-manganese stainless savings, can be used as a bowl, spoon, plate, chopsticks, cutlery and other tableware. If use steel and iron cutlery is too soft, such as pure iron do cookware, better toughness, but the strength is bad, kitchen supplies plus manganese can enhance the toughness and wear resistance of the steel and iron materials if cause.

　　Manganese is an essential trace element, which constitute the body several important physiological role of the enzyme, the normal daily food intake of manganese is 3-9 mg. human body lack of manganese can cause manganese deficiency, but manganese poisoning can be caused by too much, such as long-term exposure to manganese compounds. Chronic manganese poisoning generally in contact with manganese dust, show up 3-5 years or more after. Because manganese is a heavy metal, manganese poisoning cases are most common in the mining, transportation, grinding and manganese screening exposure to manganese dust workers, followed by manganese welding rod used for the production of manganese alloy smelting workers, welders, and processing of ferromanganese alloy mill workers. Chronic poisoning can damage the extrapyramidal produce clinical manifestations of parkinsonism.
