Austenitic steel

In recent years, the development trend of stainless steel welded pipes has been relatively good. Regardless of the scale, quality, and production technology, there have been relatively large advances, and in particular its demand areas have also gradually expanded. In addition, as the stainless stee


304 stainless steel is a common material in stainless steel, with a density of 793 g cm3. It is also called 18 8 stainless steel in the industry. High temperature resistance of 800 ℃, with the characteristics of good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry.
