Introduction of GB/T 4358-1995

1 Scope This standard specifies the classification, dimension, shape, technical requirements, test methods, inspection rules, packing, marking, quality certification of the carbon spring steel wire for significant use. This standard is applicable to manufacturing such springs with high stress or the valve springs for significant use that will not pass through heat treatment or only through low temperature tempering. 2 Normative references The following standards contain provisions which, through reference in this standard, constitute provisions of this standard. At time of publication, the editions indicated are valid. All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
