W18Cr4V High Speed Steel

1. Forging temperature range W18Cr4V belong to high alloy steel, its characteristic is slow, forging heating temperature narrow range.Beginning temperature for forging ° C, 11 ~ 1150 end forging temperature for 900 ~ 950 ° C. 2. Heating time determinationThe thermal conductivity of the poor W18Cr4V steel, which normally takes piecewise heating. Low temperature section heating temperature is 800 ~ 9 °C, heating time according to the general 1mi n/mm calculation. High temperature, heating time when fast-heat general press 0. 5mi n/mm calculation. When heated, in order to prevent overheating or burning, shall strictly control limit temperature. Meanwhile, furnace blank want to install furnace is right amount,Also kept flip, to make its inside and outside temperature uniformity.
