For designating the product,the designation specified in the relevant dimensional standard shall be used.Any properties the products are
15、 to have shall be specified when ordering, together with the relevant testmethods.4 Mechanical properties at ambient temperatureThe products shall have the properties specified in table 1.5 Chemical compositionThe chemical composition of wrought nickel and nickel alloy pipes and tubes shall be as sp

17、ordance withDIN 50125 and DIN EN 10002-1. It is recommended that the hardness be determined based onDIN EN ISO 6506-1, using a ball diameter of 2,5 mm and a test force of 612,9 N (HBW 2,5/62,5). Where this isnot possible, the Vickers hardness test in accordance with DIN EN ISO 6507-1 shall be carrie
