Defines the requisites for cold rolled carbon and low alloy steel strip for the manufacture of springs. Relates to material from 0.1 mm to 5 mm in thickness and from 3 mm to 450 mm in width and material supplied in the annealed, annealed and skin passed or the temper rolled conditions, having one of six edge conditions and any one of two surface finishes. Includes sections on definitions, designation system, steelmaking process, chemical composition, mechanical properties, response to heat treatment, edge conditions, surface finish, dimensional tolerances, freedom from defects, decarburization, non-metallic inclusions, number of tests, hardness test, bend test, retests, test certificates, inspection, packaging and identification.
