This is a resulphurized steel with good machinability and surface finish, but not as good as the standard screw stocks. Its case hardening characteristics are superior and it develops an excellent core. It brazes satisfactorily but has no more than fair welding properties. This is a more ductile steel than others of lower manganese content and it cold forms well. Its machinability is rated at 89% of 1212.
Shape
Round, Hexagon
Grade
1117
Tolerance
Meets cold finished carbon steel bar manufacturing tolerances
Application
More important parts where the combined properties of good machining and superior case hardening are required, but where some machinability and finish (compared with standard screw stocks) can be sacrificed.
