in304The marking of the material is added to the stainless steel pipe, regardless of the standard model.06Cr19Ni10), or the base price of the Japanese bidSUS304), or the bottom of the US label304All of this is merely to better confirm that the material is genuine304Stainless steel plate.

　　304LStainless steel plates are also known as low-carbon stainless steel plates. In general application scenarios, their characteristics and304Stainless steel plates are similar.304Stainless steel plates are widely used steel grades. They have good corrosion resistance, high-temperature resistance, ultra-low-temperature compressive strength and mechanical equipment characteristics. They can also be used for heat treatment such as stamping and bending, and are less likely to experience hardening during heat treatment.

　　Furthermore, in China's high-pressure vessel standardsGB150-1998In the4.1.6Requirement: The application temperature of martensitic stainless steel plates should be higher than525℃At that time, the carbon content in the steel should not be less than 0.04%.
