A method for manufacturing a coiled spring having a high fatigue strength to be used for example as a suspension spring of a car using a rod of tensile strength 1910 to N/mm 2 and diameter 8 to 17 mm. In a cold coiling step, the rod is formed into a coil. Annealing is then carried out to remove strains having arisen inside the coil during the coiling step.

Hot winding is a spring manufacturing technique used for thicker wire or bar stock. The spring material can be coiled into springs if the metal is heated to make it flexible. Standard industrial coiling machines can handle steel bars up to 3 inches in diameter, and custom springs have reportedly been made from bars as much as 6 inches thick.
