Chemical composition %   of grade   16MnCr5 (1.7131)
Elements not quoted in this table shall not be intentionally added to the steel without the agreement of the purchaser, other than for the purpose of finishing the heat.
Steels with improved machinability as a result of the addition of lead or higher sulfur contents, depending on the manufacturing process up to around 0.1 % S, may be supplied on request. In this case, the upper limit of the manganese content may be increased by 0.15 %
