What's the difference between 304 stainless steel

　　　I believe you all know that the spring is made of stainless steel, but when you customize the stainless steel spring, you often wonder whether to use 201 stainless steel or 304 stainless steel? Why are the prices so different? Today, Dongguan walsai spring factory will summarize the differences between the two kinds of stainless steel materials, and then we will know what the differences are.

　　(1) specification: the commonly used stainless steel plate is divided into 201 stainless steel and 304 stainless steel. Actually, the composition is different. 304 has better quality, but the price is expensive, and 201 is worse. 304 is imported stainless steel plate, 201 is domestic stainless steel plate.

　　(2) composition: the content of nickel is different; 201 is composed of 17cr-4.5ni-6mn-n, which is a kind of low nickel, and 301 steel is an alternative steel. After cold working, it is magnetic and used in railway vehicles; 304 is composed of 18cr-9ni, which is the most widely used stainless steel and heat-resistant steel. It is used in food production equipment, Xitong chemical equipment, nuclear energy, etc. The price of 304 is relatively expensive now, generally close to 50000 tons, but at least 304 can ensure that it will not rust in the use process.
