Cold Drawn Spring Wire for Grades Classification

Spring wire can be supplied in three grades according to tensile strength. The grade of spring wire used depends on the stress level and the nature of the duty. Where springs are subjected to static stresses or infrequent dynamic loading a wire grade for static duty (S) shall be used. In the other cases with […]
