Chemical Composition(%)

Heat Treatment

Annealed: Heat slowly to 1550°-1600°F, hold until entire mass is heated through, and cool slowly in the furnace (40°F per hour) to about 1000°F, after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization.

Capacity

1,000 ton per month.

Test
