This is a special steel casting and machining part produced by balasen company recently.
the material is 42CrMo4. This is to export to Europe customer.
We casted a ring firstly, then the material go through heat treatment process. after that we make additional specimen to test the mechanical property and chemical composition to ensure the material quality.
Then we make a full machining for all surface per customer drawing.
We have final geometrical measurements and dimension inspection.
we made a soundness packing at the last step to ship to client.
What a beautiful part!
