FDAC具有快速制模,優良的高溫強度與耐磨性。硬度在出廠時就已經達到HRC40-44。所以不需要熱處理就可以直接用于產品生產??梢源蟠鬁p少模具加工的時間。主要用在鋁,鋅,鎂合金壓鑄模具和擠壓模具上。也經常應用在高硬塑膠模具中(如頂出機構中的司筒),如發動機模具等。

化學成分:

C Si S P Mn Cr V Mo
0.33-0.42 0.80-1.20
0.10-0.15 0.03 0.55-0.75 4.80-5.50 0.30-0.80 1.20-1.60

熱處理:

退火:加熱至800-850℃,在此溫度中停留二小時,在爐中任其漸冷。 淬火: 550-600℃,次加熱至850-900℃,再加熱至a.l000-1.040℃。b.1.040-1.080℃在油中淬硬(a.較需韌性工具; b.較需熱作時硬度工具) 回火:緩熱至550-680℃,在此溫度中停留,然后在靜止空氣中冷卻,回火應在二次。 硬度:HRC530℃以下。
