TP 304 / Ss304 Stainless Steel Pipe ECONNOMIC ROLE

TP 304/ Ss304 Stainless steel seamless pipe export is an important part of China’s export economy, it plays an important role in stimulating China’s economic growth, however, China’s foreign trade of stainless steel, stainless steel of China’s export met great resistance.

The TP 304/ Ss304 stainless steel pipe is used as a stainless steel tube and is used for the use of food equipment, general chemical equipment and equipment for the atomic energy industry.

The stainless steel rust resistance is stronger than the stainless steel materials of the 200 series. It is also good for high temperature, which can be up to 1000-1200 degrees. TP304/SS304 stainless steel has excellent corrosion resistance and good corrosion resistance.

304 stainless steel material has a strong resistance to corrosion in nitric acid, which is below the boiling temperature of less than 65%. Alkaline solution and most organic acids and inorganic acids also have good corrosion resistance.

TP304/ Ss304 304 Stainless Steel Pipe Excutive Standard:

For 304 stainless steel, the Ni element in its composition is very important, which directly determines the corrosion resistance of 304 stainless steel and its value.
The most important elements in 304 are Ni and Cr, but they are not limited to these two elements.

Specific requirements are specified by product standards. The common judgment in the industry is that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered as 304 stainless steel.

This is why the industry calls this type of stainless steel 18/8 stainless steel.

In fact, the relevant product standards have very clear regulations for 304, and these product standards have some differences for different shapes of stainless steel.

Below are some common product standards and tests.

To determine whether a material is 304 stainless steel, it must meet the requirements of each element in the product standard. As long as one does not meet the requirements, it cannot be called 304 stainless steel.

The above four standards are just a few common standards. In fact, there are more than these standards mentioned in ASTM and JIS 304.

In fact, each standard has different requirements for 304, so to determine whether a material is 304, the accurate expression should be whether it meets the 304 requirements in a product standard.

The material certificate generally needs to issue the following types of reports: detailed standard specification comparison: as of 2015-12-08
