NOTES |
FORGING |
1760-2050° F |
Cool slowly |
Should not forge any higher than 2050° F. Cool slowly in furnace or in some other insulating media. |
ANNEALING |
1600-1650° F |
Cool slowly in furnace at a rate not exceeding 50° F per hour to 1000° F |
Heat at a rate not exceeding 400° F per hour and hold at temperature for one hour per inch of thickness. |
STRESS RELIEVING |
1200-1250° F |
Cool slowly |
Hold for one hour per inch of thickness with a 2 hour minimum.
Stress relieve after rough machining |
PREHEATING |
1150-1250° F Equalize then 1400-1450° F
|
Air or pressurized gas. |
Complex tools should use a double preheat |
HARDENING |
1850-1950° F |
Air cool to under 100° F for maximum hardness response |
For maximum wear, use high side of range. For maximum toughness, use low side of range. |
TEMPERING |
(See Chart) |
Air. |
Temper immediately after quenching. The desired secondary hardening of Vertex will support higher tempering temperatures 970° F and above. Double temper. |
