Book Description

Excerpt from Rust Prevention: A Treatise on the Preservation of Structural Steel Used in Bridges, Buildings, Fire Escapes, and Sheet Steel Used in Buildings, Metal Siding, Roofing, Smokestacks, Boiler Fronts, and Standpipes, Etc The use of steel has increased so rapidly within the past ten years that the keen competition in cost of production between the manufacturers thereof, has caused an enormous amount of this metal (particularly in Sheet Steel and Terne Plates for exterior use) to be thrown upon the market, of a quality unsatisfactory to those who have to shoulder the responsibility of its proper maintenance. Since the advent of the Bessemer process of making steel cheaply, the use of "charcoal iron" has comparatively decreased. Iron ore is very rarely reduced to pure metallic iron for commercial purposes, consequently the foreign substances which have not become eliminated from it constitutes part of the material entering into its transformation into steel. The progress of disintegration of steel exposed to reactionary agencies largely depends upon the quality of the metal, nickel steel, for example, being but very slightly susceptible to corrosive action, while Bessemer process steel being the reverse. The intention of this treatise is to deal briefly with the protection of the surface of the metal, so that corrosive action may be prevented from exterior sources, and in pursuing this course, we must of necessity carry on the discussion with the understanding that the steel or iron exposed to corrosion is of the quality which ordinarily comes from the mill, leaving the question of placing cheap and better steel upon the market for structural purposes to those who manufacture it.
