1.4541

X6CrNiTi18-10

The 1.4541 (X6CrNiTi18-10 (AISI 321)) is an austenitic, stainless [[element:Cr|chromium]]-[[element:Ni|nickel]] steel — non-magnetic, tough all the way through, and generally easy to weld. The [[element:Mo|molybdenum]] grades (like 1.4404 or 1.4571) also stand up better to chlorides. Known weak points when welding: high thermal expansion ([[glossary:verzug|distortion]]), tendency to [[glossary:heissriss|hot cracking]], and the risk of [[glossary:chromverarmung|chromium depletion]] in the [[glossary:waermeeinflusszone|heat-affected zone]]. Typical composition: 0.05 % C, 17.5 % Cr, 1.2 % Mn, 9.5 % Ni, 0.5 % Si, 0.25–0.7 % Ti.
