Figure 6 shows a condition which is familiar to those whohave closely inspected old hopper cars. The inside of hopperside sheets build up with corrosion products. Examination ofthese products has shown them to be substantially the same asthe rust that forms on steel which has been exposed only toatmospheric conditions. There is no reason to believe that theseproducts can be formed by any means other than atmosphericconditions. The resistance of USS COR-TEX to atmospheric corrosion,to corrosion in running acid water which had filtered throughcoal in a coal mine, to abrasion and to denting indicates that 31 this material should be more satisfactory for use in cars to beplaced in normal service than the steel used in present ecjui])-. FISURE 6.—The corrosion of open cars usually results in the formation of corrosionproducts similar to the built-up layers to be seen on the hopper side sheet in the photograph. ment- Hopper cars and mine cars of COR-TEN are now inservice. APPLICATIONS While COR-TEN steel is a comparatively recent develop-ment, it has already found considerable application in a greatvariety of equipment such as freight and passenger cars, stream-lined trains, street cars and buses, tank trucks and mine cars.
