Stainless steel is made from iron-chromium alloys that incorporate other trace elements. Due to its good metal function and corrosion resistance compared to other metals, the finished vessel is beautiful and durable. Therefore, more and more stainless steel was used to create stainless steel kitchen utensils and gradually put into the public. Stainless steel kitchen utensils are resistant to erosion and high temperatures, but they are also rusted when they are contaminated with acid or polished with hard materials such as sandpaper and fine sand. Before use, such as stainless steel kitchen utensils coated with a layer of vegetable oil film, and baked on the fire, you can avoid the rust, to extend its useful life.
However, if the user lacks relevant knowledge and misuse, the trace metal elements in stainless steel will also slowly accumulate in the human body. When a certain limit is reached, it will hinder human health. The composition and type of stainless steel: Stainless steel is an alloy composed of iron, chromium, carbon and many different elements of pores. Iron is an essential element and chromium is the first most important alloying element. In general, at least 11% of chromium is known as stainless steel. Iron-carbon is beneficial and harmless without saying much.
