440C is a hardenable chromium steel. It has one of the highest attainable hardnesses of the corrosion and heat resisting grades. This grade is magnetic at all times. For those applications where superior machinability is desired and where slightly lower corrosion resistance is satisfactory 440C Is 440a stainless steel good for knives?- [Complete Steel Edge Retention:with a maximum HRC of 58, its a hard knife with decent Edge retention. Corrosion Resistance:440a has excellent corrosion resistance due to the high presence of chromium in it. 18 % is quite high compared to other steel, and this is why it may be the best stainless steel for corrosion resistance. Wear Resistance:the 0.75% carbon grants the 440a stainless steel a good wear Passivation of 440C Material Products FinishingApr 01, 2002 · The parts are usually processed in stainless steel baskets. N.S. Answer:Your problem sounds unusual since a 440C material should not etch in the sodium dichromate/nitric acid bath. The 440C is on the border of needing an additional oxidizing element like sodium dichromate to keep it from etching (based on chrome content of about 17% nominal).
When to passivate 440C component -- before or after grinding? 2004. Q. This concerns passivation of 440C stainless steel that has been hardened to Rc 55-60. Here is my question:Should I passivate before grinding or after grinding? Moreover, another sub question:How to brighten it, that is, remove the tawny color that it takes on from hardening?
