Strong magnetic stainless steel ( 430). Is containing chromium ( chrome) And those that do not contain nickel, become the Cr stainless steel, as the corrosion resistant ability. While stainless steel is chromium and nickel, belong to the more stable the nickel element, then its ability to resist corrosion nature better than stainless iron a lot! Because the nickel price is more expensive, so from a cost on the stainless steel is higher than stainless iron, plus the ability to resist corrosion, stainless steel price is 1/4 ~ 1/3 higher than stainless iron. Home supplies stainless steel can be divided into 430 ( 18 - 0) , 304 ( 18 - 8) , 18 - 10 at three levels. 430 ( 18 - 0) Stainless steel: + 12% or more of the chromium iron, can prevent oxidation caused by natural factors, called stainless steel, code-named 430, therefore also known as the 430 stainless steel. But 430 stainless steel could not resist the chemicals in the air caused by oxidation, 430 stainless steel is not commonly used after period of time, will still be due to factors other than natural oxidation ( Rust) The situation; 18 - 8 stainless steel, chromium iron + 18% + 8% nickel, chemical resistance of oxidation, this kind of stainless steel code for 304, so also known as the 304 stainless steel. 18 - Stainless steel: but the chemical composition in the air more and more, some places with high levels of pollution even 304 will be rusty; So some products will use 10% of the nickel to make, in order to make it more durable and resistance to corrosion, the stainless steel is called 18 10 stainless steel. On some dishes that have similar 'using 18 10 stainless steel materials'. Stainless steel according to the microstructure can be divided into three categories: austenitic stainless steel and ferritic and martensitic stainless steel stainless steel. Stainless steel mainly of iron, chromium, nickel alloy, in addition to containing manganese, titanium, cobalt, molybdenum and other trace elements and cadmium, which makes stainless steel performance is stable, with no rust and corrosion resistance. Austenite size stainless steel because of the particularity of the molecular structure of the internal not easy to be magnetized.
