依據RoHS指令2005/95/EC附錄的第六點：
Lead as an alloying element in steel containing up to 0,35 % lead by weight, aluminium containing up to 0,4 % lead by weight and as a copper alloy containing up to 4 % lead by weight.
鉛若用於下列材質中，並為其合金元素之一的話，則鉛含量可擴大成如下所述：鋼材可容許 0.35%，鋁材可容許 0.4%，銅合金可容許 4%。
所以只要是鋼合金，不管是什麼型號，鉛含量只要不超過0.35%(3500ppm)都是可以接受的。
