Which Of The Following Processing Routes Would Be Expected To Keep The Strength Of A Normalised Medium Carbon Steel Roug 1 (38.2 KiB) Viewed 21 times

Which of the following processing routes would be expected to keep the strength of a normalised medium carbon steel roughly the same at the end of the process as it was at the start? O Hot forge to the rough shape, perform a qench and temper treatment and finalise the dimensions with a grinding stage. O Austenitise the steel and slow cool to room temperature, cold work to the rough shape and grind to good dimensional accuracy. Reheat to the austenite temperature, cool to above the Ms and hold for a long time to form bainite. O Heat the steel to below the eutectoid temperature for a few hours, cold work it to get the proper shape and then get the final dimensions with a grinding stage. O Cold work it into the correct shape, heat below the eutectoid temperature for a few hours, final machining step for high dimensional accuracy. Heat to the austenite region and slow cool.
