The Development of Auto-Structural Materials in the Chinese Automotive Industry 891260

The automotive industry of China is reviewed with a brief description of the big two -- the First Automobile Works (FAW) and the Second Automobile Works (SAW). China has so far mainly dedicated itself to truck manufacture, but car production is gathering momentum.The Chinese auto industry pays considerable attention to economy in the use of strategic alloying elements. Emphasis is laid on the use of abundant elements, e.g. SAW has developed an alloy steel system based on Si-Mn-V-B and an HSLA system using Si-Mn-V-Ti-Re. These steels are in regular production for large scale truck manufacture, thus conserving considerable quantities of alloy elements such as nickel, chromium and molybdenum.Discussion on base metals highlights the technical advance of modern cast irons. Aluminum, magnesium and titanium are also evaluated.The paper is concluded by consideration of the use of non- metals with discussions of timber, bamboo and plastics.
