WebHigh carbon steel is also used for the ring gear of a powertrain. However, since these two base materials contain high carbon content, the weldability is not very good because both of these materials have high equivalent carbon content (CE). The CE can be calculated by the following equation: CE = C + Mn/6 + (Cr + Mo + V)/5 + (Ni + Cu)/15 Web25 de nov. de 2024 · The heat affected zone (or simply HAZ) is something that occurs when metal is subject to high temperatures.
