In the 40 years between 1960 and 1999, the production of stainless-steel in Western countries jumped from 2.15 million tonnes to 17.28 million tonnes, an increase of about eight times, with an average annual growth rate of about 5.5%. Stainless-steel is mainly used in kitchens, household appliances, transport, construction and civil engineering. In the kitchen appliances mainly sinks and electrical and gas water heaters, home appliances are mainly automatic washing machine drums. From the viewpoint of environmental protection such as energy saving and recycling, the demand for stainless-steel is expected to expand further.
Stainless steel has many excellent properties not found in other metals and is a material with excellent durability and recyclability, and will be used in a wide range of applications in the future in response to changing times.
