scope:

This Standard applies to bars and wire of the materials according to Table 1 of dimensions up to those given in Table 4. These materials are normally used for bolts and nuts according to DIN 267 Part 13 -Bolts, screws, nuts and similar threaded and formed parts; technical conditions of delivery; bolts and nuts primarily of steels exhibiting toughness at subzero temperatures and hightemperature steels -at temperatures above about 300 °C up to the maximum service temperatures quoted in Table 4 as a guide for long-term operation. These temperatures may be exceeded where the properties of the material are adequate for the service stresses. The criterion is the total loading on the material resulting from temperature, mechanical loading and the ambient media during the proposed time of operation.
