GRAY IRON CASTINGS

Class 25,30,35,40 tensile and heat resistant irons.

Gray Iron has a dense gray structure and offers excellent machinability. Grades 25, 30, 35 and 40 can fill specific requirements for hardness and wear, and heat treatments can yield even higher mechanical properties. Popular applications for gray iron include diesel and gasoline engine blocks and cylinder liners, and structural machine components where vibration dampening is required.
