now and the prevalence of various stainless steel products, stainless steel furniture to make a lot of people are beginning to understand the magic of the steel. To know more people know, stainless steel has a lot of models, their computation can reach more than 100 kinds. Among these different models, two kinds of models 304 and 201 is very widely used in our life. Believe that buying a stainless steel furniture knows, 304 stainless steel furniture are much more expensive than 201 stainless steel furniture on, what reason is this? This must first start with the difference between the two, in fact, the stainless steel is on the basis of iron and carbon with some of the elements such as nickel, chromium, manganese, in order to increase its corrosion resistance, make its not easy to rust. And the difference between 304 stainless steel and 201 stainless steel is that adding element types and a variety of different. 304 stainless steel containing more than 201 stainless steel, nickel, chromium element manganese element is less than 201 stainless steel. Among these elements of chromium and nickel price is higher, so the 304 stainless steel to be a lot more expensive than 201 stainless steel. Many knowledgeable people know, must have elements in nickel is stainless steel, and the amount of nickel element, directly affect the corrosion resistance of the material, this also is why stronger corrosion resistance of 304-201. 304 stainless steel and 201 stainless steel how difference: this is very simple, now on the market there is a kind of liquid medicine can be tested directly. Drug usage is water droplets on a clean stainless steel plate, if immediately become reddish brown, is 201 stainless steel, if after a period of time to present beige is 304 stainless steel. Is the principle of the differential, strong corrosion resistance is 304, the poor is 201 such is why 304 stainless steel is more expensive than 201 stainless steel is introduced, the cause of 304 stainless steel in addition to actually on the corrosion resistance is higher than 201 stainless steel in many, on top of other physical properties and safety performance is also higher. 304 stainless steel toughness, not easy to break, can produce all kinds of complex process of stainless steel products. Additional manganese element is a kind of harmful element to human body, so if this kind of element content high, used as tableware is very dangerous. The manganese content of 201 stainless steel has a 10%, 304 2% so 304 stainless steel is more secure.
