Stainless Steels Welding Guide - Lincoln Electric

STEEL The austenitic stainless steels contain 16-26% Cr, 8-24% Ni + Mn, up to 0.40% C and small amounts of a few other elements such as Mo, Ti, Nb (Cb) and Ta. The balance between the Cr and Ni + Mn is normally adjusted to provide a microstructure of 90-100% austenite. These alloys are characterized by good strength and high toughness over a wide Steels Composition AISI-SAE Standard Carbon Steels Free machining steel with lead also allow for higher machining rates. Free machining steel costs 15 to 20% more than a standard steel, but this is made up by increased machining speeds, larger cuts, and longer tool life. The disadvantages of free machining steel are:ductility is decreased; impact resistance is reduced; copper-based brazed
