Life is now a large number of tableware in fact, as long as the quality of clearance, not inferior products, usually use are no problem, the human body will not cause harm. Stainless steel bowl is also the case, the focus is how to choose a quality clearance stainless steel bowl. Usually stainless steel tableware often marked '13 -0 ', '18 -0' and '18 -8 'three code, code in front of the number represents the chromium content, followed by the number of nickel content, the higher the amount of nickel The quality of the better, such as '13 -0 'that is 13% chromium, non-nickel. Stainless steel tableware products should be printed on the code font, if not printed like a code is a fake bowl, not suitable for use as a cutlery. Household goods stainless steel can be divided into 430, 304 (18-8), 18-10 three grades. 430 stainless steel: iron more than 12% chromium can prevent the oxidation caused by natural factors, called stainless steel, in the jis code 430, it is also known as 430 stainless steel, but 430 stainless steel can not resist the chemical substances in the air caused Of the oxidation, 430 stainless steel is not often used for some time, will still be due to non-natural factors and oxidation (rust) situation; 18-8 stainless steel: iron 18% chromium 8% nickel, can be resistant to chemical oxidation, this stainless steel in the jis code for the 304, it is also known as 304 stainless steel; 18-10 stainless steel: but the chemical composition of the air more and more, some of the more serious pollution even 304 will be rusty; so some high-level supplies will be made with 10% nickel to make it more durable More resistant to corrosion, this stainless steel is called 18-10 stainless steel. In some tableware instructions have similar '18-10 the most advanced medical stainless steel' argument. Stainless steel according to the metallographic organization can be divided into three categories: austenite Stainless steel, ferritic stainless steel and martensitic stainless steel. The main components of stainless steel are iron, chromium, nickel alloy, in addition to manganese, titanium, cobalt, molybdenum and cadmium and other trace elements, which makes stainless steel stable performance, And corrosion resistance. Austenitic stainless steel due to the special nature of the internal molecular structure, making it difficult to be magnetized.
