WebP E = C + Mn + Mo + Cr/3 + Si/4 + 3.5 (10P + 5Sb + 4Sn + As) The maximum value for this expression to avoid serious embrittlement depends on the welding process but is given as 2.8-3.0 where coarse grained weld metal exists. Step cooling can reveal the susceptibility of a steel to temper embrittlement. WebCr(VI) can also be formed when performing “hot work” such as welding on stainless steel, melting chromium metal, or heating refractory bricks in kilns. In these situa-tions the chromium is not originally hexavalent, but the high temperatures involved in the process result in oxi-dation that converts the chromium to a hexavalent state.
