Note: Type of iron sheet: 430 stainless iron. 430 stainless iron is also known as 430 stainless steel, with the national standard grade being 1Cr17. The 400 series stainless steel is ferritic and can be referred to as stainless iron. 430 stainless iron has excellent corrosion resistance and is a versatile steel grade. Its thermal conductivity is better than that of austenitic steel, while its thermal expansion coefficient is lower than that of austenitic steel. It resists thermal fatigue. Titanium, a stabilizing element, is added to enhance the mechanical properties of the weld area. It is used in architectural decoration, fuel burner components, household appliances, and electronic parts (also used in air conditioners). The state of 430 stainless iron varies, resulting in different levels of dirt resistance and corrosion resistance. There are several states of 430 stainless iron: 1D, 2D, 2B, HL, BA, Mirror, and various other surface treatment states.

Also known as: Stainless steel refers to steel that resists corrosion by weak corrosive media such as air, steam, and water, as well as chemical erosive media like acids, alkalis, and salts. It is also called rust-resistant acid-resistant steel. In practical applications, steel resistant to weak corrosive media is commonly referred to as stainless steel, while steel resistant to chemical media is called acid-resistant steel. Due to the differences in chemical composition, the former may not necessarily resist chemical corrosion, whereas the latter generally possesses rust resistance. The corrosion resistance of stainless steel depends on the alloy elements contained in the steel.
