Language(s)

English

Published date

10-31-1988

Updates requirements to reflect changes in spring manufacture, the need for fine-grain steels and, for certain applications, closely controlled hardenability. Introduces requirements for average maximum levels of non-metallic inclusion and depth of decarburization of surface defects.
