A comparison of US and Japanese produced Automotive springs was made regarding the following:1. Material used2. Quality and Grade of steela. Incidental alloying elementsb. Non-metallic inclusionsc. Grain size3. Scale and DecarburizingResults of comparison were follows:1. US springs were made of Silicon-Manganese steel, Chromium steel and Molybdenum steels, but Japan mades were chiefly of Silicon-Manganese steels.2. The quality and grade of steels used for US springs were superior to those of Japan make.3. Scale and decarburizing on surfaces of US spring could not be observed, but they were usually observed on surfaces of Japanese springs.
