304 stainless steel cold-rolled technology first appeared in Europe, and the backward technology can only produce very narrow cold-rolled steel sheet, the width is only 20 ~ 25mm, and later the US-made steel reached 150mm, followed by the development of very rapid in Europe and the United States , And the quality has been greatly improved.
The Soviet Union in the mid-20th century began the rolling of this sheet, sheet metal sheet production with a thickness of about 0.5 to 2.5mm. In order to meet the needs of the automotive industry, but also greatly enhanced the production dynamics, after the succession of the production line for a number of production sheet.
In China 40 years of steel production, production capacity has increased by 40 times, to 2000, production has reached the forefront of the world. In the eyes of the vast number of consumers, 304 and 201 stainless steel tube is almost not much difference, the basic look with the naked eye is no way to distinguish.
304 stainless steel plate
Here I am to give you a detailed description of how to correctly distinguish between these two different pipe it:
1, the price relative to the quality of 304 stainless steel pipe better than 201, but the price will be slightly more expensive.
2, application, 201 stainless steel pipe is 301 alternative steel, after cold after the magnetic. The 304 is a good heat resistance, mainly used in food production equipment.
3, composition, the biggest difference between the two is whether the composition of nickel, 304 can be used to ensure that the process will not easily rust.
