Machining Stainless Steel 440C. Stainless steel 440C is a martensitic stainless alloy with 18% chromium 1.20% carbon. The 'C' suffix stands for ' carbon ' since it is the stainless steel alloy with the highest carbon content in the 400 series. The high carbon content yields very high strength at the expense of poor machinability, around 35%.. 440C resists corrosion …

Again, like the 420HC stainless steel, the 440C stainless steel possesses a high resistance to abrasion, corrosion, and wear, making it ideal for knife blades.

For 440C and similar, they do not discuss the quench media much except to say oil quenched or air cooled, and that oil is most generally used unless parts are of complex shapes. Then, air quench is employed to prevent distortion and quench cracking. From their data, it appears oil quench will produce maximum hardness of HRC 60 to 62.
