These mechanical properties make 310S Stainless Tube Shields suitable for applications requiring high strength and corrosion resistance, such as architectural structures, marine environments, and chemical processing.
In order to solve the cumbersome and difficult to remember stainless steel grades, improve the practicability of the brand representation, and the contrast with the international standard grades, China has formulated the "Universal Code System for Steel and Alloy Grades", such as 06Cr19Ni10, corresponding to 304. Different grades of stainless steel have different ingredients, but they all have a national standard. The standards of each country are also different.
