SUS443:
Chemical composition: SUS443 is a low chromium and high nickel stainless steel. Its chemical composition contains about 17- 19% chromium and about 1-2% nickel. In addition, it also contains elements such as aluminum, molybdenum, titanium and copper.
-Features: Compared with SUS304, SUS443 is a ferritic stainless steel with good corrosion resistance and high temperature resistance. It is a kind of heat-resistant stainless steel, which is suitable for application in high temperature environment.
Application: Because of its heat resistance, SUS443 is often used as an element in high-temperature environment, such as gas burner, high-temperature furnace, automobile exhaust system and heat exchanger.
SUS304:
-chemical composition: SUS304 is an austenitic stainless steel, and its chemical composition contains about 18-20% chromium and about 8- 10.5% nickel. In addition, it also contains less elements such as carbon, silicon and manganese.
-Characteristics: SUS304 has excellent corrosion resistance, high plasticity and strength. It can resist corrosion under the most common environmental conditions and is easy to be processed into various shapes.
-Application: SUS304 is widely used in various fields, including food processing equipment, chemical equipment, medical instruments, building structures and household items.
