Corrosion Resistance
440C stainless steel sheets have excellent resistance to various types of corrosion due to the large amounts of chromium they have. They can maintain their corrosion resistance to:
- foods
- freshwater
- acids
- alkaline solutions
- chlorine bearing environments
- other atmospheres
Moreover, 440C stainless steel sheets are high alloyed grades that have better corrosion resistance than low alloyed grades. In many conditions, 440C SS sheets have corrosion resistance that is similar to that of 304 SS sheets.
Features
440C stainless steel sheets offer many features. Features such as:
Hardenable
By heat treatment, 440C stainless steel sheets can be hardened.
The 440C stainless steel sheets can maintain their strength and resist scaling at high temperatures.
Hygienic
440C stainless steel sheets are easy to clean which makes them perfect for applications where high hygienic standards must be met.
Aesthetic Appearance
