Free cutting steels also known as free machining steels are those steels which form small chips when machined. This increases the machinability of the material by breaking the chips into small pieces, thus avoiding their entanglement in the machinery. This enables automatic run of the equipment without human interaction. Free cutting steels with lead also allow for higher machining rates. As a thumb rule, free cutting steel normally costs 15 % to 20 % more than the standard steel. However this is made up by increased machining speeds, larger cuts, and longer tool life.
Market Dynamics:
For instance, according to the American Iron and Steel (AIS) in September 2022, provision requires (United States Department of Agriculture) USDA Rural Utilities Service (RUS) Water and Environmental Programs (WEP) assistance recipients to use iron and steel products that are produced in the U.S. Moreover, the household appliances that are used to process food items mostly have to be food grade as they comes in contact with the food items regularly. For instance, according to Section 409(h)(2)(C) of the Federal Food, Drug, and Cosmetic Act (the Act) in January 2022, states that an FCN is effective for the manufacturer, the Food Contact Substance (FCS), and the conditions of use identified in the notification and not effective for a similar or identical substance produced or prepared by a manufacturer other than a manufacturer identified in the prior notification. FCNs are proprietary to the manufacturer for which the notification is effective, therefore, the FCS must be obtained from that manufacturer.
In the field of home appliances, free machining steel is used abundantly for exteriors, chasses, panels, and motor parts, etc. free machining steel accounts for large proportions of the materials used in home appliances, although, its use has somewhat decreased since recycling began in earnest. Free machining steel, which is an abundantly available low-cost material has long been employed for home appliances because of its strength and formability. The use of surface-treated steel sheet having better corrosion resistance (longer life) and aesthetic appeal has been increasing. Surface-treated steel sheet has been subjected to plating, conversion coating or painting to impart good corrosion resistance to the steel sheet. For indoor home appliances, electro-galvanized steel sheet with a coating weight of 20 g/m2 is normally used. The purpose of this is to restrain red rust on steel by taking advantage of the preferential corrosion (sacrificial protection) of zinc under general conditions.
