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
Olympic Steel Olympic Steel Olympic Steel, Inc. is a steel processor based in Cleveland, Ohio. The company processes and distributes processed carbon, coated and stainless flat-rolled sheet, and coil and plate steel products primarily in the United States. The company owns 17 facilities throughout the eastern-half of the United States and 1 in Mexico. Its services include cutting-to-length, slitting, and shearing. It also offers value-added processes such as blanking, tempering, plate burning, precision machining, welding, and fabricating and painting to process steel to specified lengths, widths, and shapes. It also owns two subsidiaries, Chicago Tube and Iron and Integrity Stainless. Olympic Steel
