Chemical composition %   of grade   11SMn30 (1.0715):   EN 10277-3-2008
If, by metallurgical techniques, the formation of special oxides is guaranteed, a Si content of 0.10 to 0.40 % can be agreed
Elements 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.

Properties of grade   11SMn30 (1.0715)
Weldability: Due to the high sulphur and phophorus content free-cutting steels not destined to heat treatment are not generally recommended for welding.
Machinability: This steel grade is marked by a good machinability on machine tools and by an easy fragmentation of chips.
