The graph bars on the material properties cards further below compare AISI 321 stainless steel to: wrought austenitic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

SS 321, Type 321, WNR 1.4541, UNS S32100, AISI 321, … As parent platematerial Grade 347 is only occasionally used. 321 and 347 have excellent forming and weldingcharacteristics like other austenitic grades, it is readilybrake or roll-formed and have outstandingwelding characteristics. Post-weld annealing is not required.

Commercial rolled AISI 321 stainless steel samples were irradiated with Al+ ions with an energy of 80 keV and fluence of 1017 ion/cm2. The effect of Al implantation on the chemical and phase composition of the steel surface layer was studied by X-ray electron spectroscopy and grazing beam mode of X-ray diffraction analysis. A thin surface layer …
