Why is heating and cooling rates not applied from ambient temperature? (per Sec-I, why is it above 425°C and per B31.1, it is 315°C)? I am in need of a technical reason for it.
Also, does it have any hidden meaning that the temperature of furnace and the item that is to be stress relieved in furnace shall be below 425°C?
