AISI 1040 square tube

applications of AISI 1040

This grade of steel is used for forged parts where the strength and toughness of the material are appropriate.

AISI1040 may be used for the manufacture of forged crankshafts and couplings, along with

a range of parts where the properties of heat-treated AISI 1040 are suited to the application.
