1 This International Standard specifies requirements for the grades of wrought steels, listed in Table 1, which are usually employed for products for which the resistance to the effects of hot gases and the products of combustion at temperatures in the region above 550 ℃ is the main requirement.
2 This International Standard is applicable to
— flat products;
— bars;
— sections;
— wire and rod;
— forgings.
NOTE 1 Heat-resisting steels for valves are covered by ISO 683-15.
NOTE 2 Corrosion-resistant stainless steels for which resistance to corrosion is of primary importance are covered by ISO 16143-1, ISO 16143-2 and ISO 16143-3.
NOTE 3 Not all of the steels included in this International Standard are necessarily available in all product forms.
NOTE 4 Wire in the cold-worked condition is covered by ISO 16143-3.
3 In addition to this International Standard, the general technical delivery requirements of ISO 404 are applicable.
