Certificates and documentation
1.3207 / S290/S390 family can be supplied with a material certificate to EN 10204, depending on producer, dimension and the requirements specified for the delivery. Tool steel is bought on W.Nr. and condition, and we write the number on the paper that the mill can carry — not a trade name the certificate does not cover. If a specific delivery hardness is to be documented, it must be on the order. EN 10204 3.1 can be supplied on a wide range of our materials.
