Abstract
Abstract A car stabilizer and a manufacturing method therefor are disclosed. In this method, a straight material of carbon steel with a carbon content of 0.10 % to 0.35 % is first directly quenched (2) by quick heating, and then bent (3) into a predetermined shape. Thereafter, the material is annealed at a low temperature of 100°C to 400°C, shot-peened (5) as required, and then coated (6). Thus, a stabilizer is obtained as a final product. The coating may be executed between the steps of quenching and bending.
