Steel not intended for heat treatmentIf, by metallurgical techniques, the formation of special oxides is guaranteed, a Si content of 0.10 to 0.40 % can be agreedElements not listed in this table shall not be intentionally added to the steel without the agreement of the purchaser, other than for the purpose of the finishing the heat. However, elements such as Te, Bi etc., may be added by the manufacturer for improving the the machinability, if this has agreed at the time of enquiry and order.
