Answers
Concept introduction:
The originally observed standard level for quality inspection, drawing out, and equipment setup is a hard, flat plate called a surface plate.
Explanation:
We have to write the proper answer of the question.
A question has been given to us.
Granite absorbs radiant heat which is a disadvantage. Granite won't rust by moisture but may distort. Strength of cast iron is more than granite for a given weight.
Final answer:
Hence, the final correct explanation of the question is ->

Grey cast iron is typically used for surface plates because the graphite flakes provide lubrication.
Surface plate:
- A real plane surface is another name for a surface plate.
- It's a standardised piece of gear that makes it possible to take exact technical measurements.
- Dimensions must be examined and confirmed in order to guarantee that all manufactured parts are of the same calibre.
- Either by artificial seasoning or natural ageing, our castings are freed of stress.
- Each surface plate has a protective cover made of wood or resin on the top surface.
- In response to a request from one of our valued clients, we construct stands with levelling screws.
A surface plate is used to inspect the job's flatness. The horizontal reference plane is also examined using a surface plate.
