By choosing the right size for a particular job, much preliminary machining can be eliminated. EXCEPTIONAL SURFACE FINISH Eliminates grinding or polishing. The exceptionally high surface finish of Silver Steel can be utilised without the need for further expensive grinding or polishing. CONTROLLED ANNEALING Maximum degree of spheroidisation. Easier, more uniform machining is possible giving greatly improved machined surface. HEAT TREATMENT HARDENING: For maximum hardness, (66 Rockwell 'C' or 850 DPN), heat to 770 C-790 C (1420 F-1450 F). Soak till uniform the quench in clean water or preferably 10% brine solution. The most satisfactory and efficient method is to heat in a salt bath and it is advisable that the temperature should be carefully controlled. The use of a pyrometer is suggested. If a muffle furnace is used the atmosphere should be slightly reducing to minimise scaling and to avoid soft spots. TEMPERING: Minimum 1 hour soak, immediately after hardening Temp Range Hardness 150 C (302 F) 63/65 Rc 200 C (392 F) 60/62 Rc 250 C (482 F) 59/61 Rc 300 C (572 F) 55/57 Rc ANNEALING: Heat slowly to 760 C-780 C (1400 F-1436 F). Soak for 1 hour per inch of section and cool slowly in the furnace.
