Corrosion resistance & temperature effects

While most stainless steels are resistant to rusting, 440 steels are slightly less corrosion resistant. This is the result of its martensitic structure, which increases its hardness but leaves it more open to corrosion than austenitic and ferritic stainless steels. This is not to say that 440 steel rusts easily, as they are more corrosion-resistant than most steels, but understand that it should not be chosen purely

for its rust resilience.

It is also important to know that 440 steels do not work well at temperature extremes. They lose their strength when at high temperatures because they over temper and become softer, and they lose their ductility at a temperature below 0o Celsius. This fact is important to any designer that wishes to implement this steel in particularly harsh environments, as 440 steel would probably not be the best choice.

Mechanical Properties

Table 1, below, shows some important mechanical properties of 440 steel. It is important to note that each alloy blend holds its own unique values, and these values fluctuate based on the strengthening treatment. Table 1 shows values for AISI 440 stainless steel, which is closest to 440C steel.
