Surface modification of martensitic stainless steel AISI 420 was achieved using friction stir processing (FSP) with a W–Re pinless tool. The microstructure, hardness and corrosion resistance of the FSPed 420 fabricated at various traverse speeds (150 to 250 mm/min) of the tool were investigated and compared with annealed and conventionally …
AISI 420 steel (SS420) is very brittle under just hardened conditions and usually must be tempered to achieve useful toughness. The tempering temperature for 420 grade stainless steel after austenitizing: 205-370 °C (400-700 °F). The corresponding tensile strength and Rockwell hardness are 1550-1930 MPa (225-280 ksi) and 48-56 HRC.
