On Stainless Steel Metro Carbody And Its Nationalization

Currently, metro car body materials as in the railway passenger car main of ordinary steel, stainless steel and aluminium alloy 3. Ordinary steel (hereinafter referred to as steel) including carbon steel and Corten steel cars. Stainless steel cars are lightweight, aluminum alloy car body. Use of lightweight vehicles will significantly save energy, reduce the maintenance costs of vehicles and lines, but also has significant long-term economic benefits. Historically, aluminum alloy car body weight better than stainless steel car, but in Japan, and Korea in urban rail transit and intercity commuter car stainless steel car body holds a distinct advantage. In recent years, the production of stainless steel cars in particular stainless steel metro cars in foreign countries also showed a rising trend.

 Canada's Bombardier company lapakajieer factory in 1982-1992 cumulative production of 1546 passenger cars, stainless steel car 89%; Japan, Tokyu car Corporation (hereinafter referred to as Tokyu) 1990-1994 production passenger car 1794, stainless steel car 62%; Korea Hanjin heavy industries Corporation (hereinafter referred to as Hanjin) 250 passenger cars 1995 production, stainless steel cars accounted for 80% ... ... The phenomenon was not by chance that it directly related to characteristics of the stainless steel car.

stainless steel car development of the world's first production of stainless steel cars was United States the Budd company. Early 60 's, Japan from the United States imported stainless steel car body technology in November 1962, making Japan the first electric railway in the South Seas 6000 series full stainless steel cars. Now Japan's leading stainless steel car technology in the world.
