View Sample Alloy Digest Data Sheet (PDF)

Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.

CRUCIBLE 303 PLUS-X is a non-hardenable austenitic chromium-nickel steel to which elements have been added to improve machinability and non-galling characteristics. Better machinability than that of standard AISI Type 303 stainless is obtained by the use of higher manganese content to give a uniquely soft and machinable sulfide inclusion. This grade is non-magnetic in the annealed condition but slightly magnetic when cold worked. Typical applications are screw machine products and all machined parts requiring good corrosion resistance or non-magnetic properties.
