Stainless steel as the common ferritic and austenitic stainless steels due to their low chromium content. Duplex stainless steels have a mixed microstructure of austenite and ferrite, the aim usually being to produce a 50/50 mix, although in commercial alloys the ratio may be 40/60. They are characterized by high chromium (19–32%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels. Duplex stainless steels have roughly twice the strength compared to austenitic stainless steels. Their mixed microstructure provides improved resistance to chloride stress corrosion cracking in comparison to austenitic stainless steels Types 304 and 316. The properties of
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.
