420 Vs. 440 Stainless Steel eHow

The tensile strength of 440 grade steel also decreases with heat treatment temperature. However, the magnitude of the tensile strength is greater, with a peak value of 2,030 megapascals at a heat treatment of 204 degrees Celsius (399.2 degrees Fahrenheit). 440 grade steel is therefore better suited to applications that are more physically demanding on the material. 420 Vs. 440 Stainless Steel eHowThe tensile strength of 440 grade steel also decreases with heat treatment temperature.

In progression from 440A-B-C, the edge properties go up, but rust resistance (and I believe toughness too) go down. Same with AUS-4-10. If I am not mistaken, 440A has around .6% carbon while 440C has around 1.0-1.1%. 440A vs 440C vs other choices for knifeJun 12, 2009 · 2002. A. John, I'd consider the corrosion resistance of 440A and 440C to be so close as to be equal. The difference between these two grades is in hardness and ductility, due to the higher carbon content of the 440C. So 440C is harder, but less able to resist an impact or bending load:which you'd expect from a harder metal.
