Specifications Chemistry Mechanical Properties

 

 

General

The A.I.S.I. grade 1215 has essentially eliminated a number of similar free machining grades, such as 1212. Both 1215 and 1213 machine considerably faster than 1212 and provide good surface finish and brazing properties. These steels are difficult to weld and are not recommended for case hardening. They are generally used where mechanical properties can be sacrificed for machinability.
