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