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 can be supplied.The typical applications of 440C include ball bearings, bushings, valve parts and cutlery.Cutlery Applications440C is particulary designed for cutlery appications requiring a high hardness and an excellent retention of the cutting edge. When this grade is ordered specifically for mirror-finish cutlery applications, material will be supplied which has been processed in such a manner as to insure the obtaining of a polished surface of “mirror finish” quality. Care should be taken in grinding and polishing this grade so that excessive heat is not produced by this operation as the resistance to staining will be lowered. In general, 440C resembles tool steels in that it required great care in fabrication and hardening.Hot rolled and annealed (This steel is not hardened and will require het treatment as part of the fabrication process.)
