General

A high manganese, medium carbon, resulphurized steel with free machining qualities and higher mechanical properties than the lower carbon steels. This grade machines at 83% of 1212 with excellent as machined finish. It induction hardens satisfactorily, but the sulfides can contribute to quench cracking. It is difficult to weld.

Shape Round, Hexagon
Grade 1144
Tolerance Meets cold finished carbon steel bar manufacturing tolerances
Application Machined parts requiring higher strength and wear resistance than is possible in the lower carbon steels.
