Stainless steel are magnetic like carbon steel. They are problematic to weld due to grain growth in the heat affected zone which reduces ductility and may result in cracks. Increasing chromium and molybdenum contents increase corrosion resistance as it does for austenitic stainless steels, however, this high alloying results in the precipitation of embrittling intermetallic phase upon welding. These microstructural problems due to welding restrict the use of ferritic stainless steels to very thin thicknesses and thus are not used in the construction of large heavy walled vessels and tanks, and structures like austenitic stainless steels. Common ferritic grades are: Type AISI
Stainless steel to produce Further information can be obtained on the websites of most producers. An example is provided here World stainless steel production figures re published every year by ISSF Overall stainless steel production (flat and long products): The stainless steel production in China accounts for more than 50% of the world production in 2017Breakdown of production by families of stainless steels in 2017: This breakdown is quite stable over the years Stainless steel is used for buildings for both practical and aesthetic reasons. Stainless steel was in vogue during the art deco period. The most famous example of this is
