Top 10 446 Stainless Steel Plate Suppliers in China - Blog

Introduction to 446 Stainless Steel Plate

446 stainless steel plate is a ferritic stainless steel known for its excellent high - temperature oxidation resistance and corrosion resistance in certain environments. It contains a relatively high amount of chromium (usually around 23 - 28%), which forms a dense oxide layer on the surface when exposed to high temperatures, protecting the steel from further oxidation. This makes it suitable for applications in high - temperature environments such as furnace parts, heat exchangers, and exhaust systems.

In addition to its high - temperature performance, 446 stainless steel also has good resistance to sulfuric acid and other corrosive media in specific concentration ranges. It has a relatively low carbon content, which helps to improve its weldability and formability to some extent. The mechanical properties of 446 stainless steel plate, such as strength and ductility, are also within a suitable range for various industrial applications.

Now, let's take a look at the top 10 446 stainless steel plate suppliers in China.
