The composition of materials contacting foodstuffs aren't the only factor controlling carcinogen migration into foodstuffs; there are other factors that can have a significant role in food safety. Examples include: the temperature of food products, the fat content of the food products and total time of contact with a surface.
Individual steel makers could use the design to promote the steel in finished products, and to help create a competitive awareness of the strength and quality of steel against aluminum and plastics. In 1964, the steel industry distributed 21 million of the Steelmark decals to be affixed to appliances and other household products.
Steel is made from iron and carbon. Cast iron is a hard, brittle material that is difficult to work, whereas steel is malleable, relatively easily formed and versatile. On its own, iron is not strong, but a low concentration of carbon – less than 1 percent, depending on the kind of steel – gives steel strength and other important properties.
Steel is an alloy composed of between 0.2 and 2.0 percent carbon, with the balance being iron. From prehistory through the creation of the blast furnace, iron was produced from iron ore as wrought iron, 99.82–100 percent Fe, and the process of making steel involved adding carbon to iron, usually in a serendipitous manner, in the forge, or via the cementation process.
