Panchmahal Steel Interview Questions, Process, and Tips

The accuracy of vernier and micrometer depends on their resolution and the skill of the user.

• The accuracy of vernier calipers is typically around 0.02 mm or 0.001 inches.

• Micrometers can have an accuracy of 0.001 mm or 0.0001 inches.

• The accuracy also depends on the skill of the user in reading and using the instruments.

• Regular calibration and maintenance can ensure consistent accuracy.

• The accuracy can also vary dependin

Thermodynamics is the study of energy and its transformations in relation to heat and work.

• Thermodynamics deals with the transfer of energy between systems and their surroundings.

• It focuses on the principles of heat, temperature, and energy conversion.

• Laws of thermodynamics govern the behavior of energy in various processes.

• Applications include power generation, refrigeration, and combustion engines.

• Example: Understand...read more

Operations like turning, facing, drilling, boring, knurling, etc. can be done on a lathe machine.

• Turning: Rotating the workpiece to remove material and create a cylindrical shape.

• Facing: Cutting a flat surface perpendicular to the axis of rotation.

• Drilling: Making a hole in the workpiece.

• Boring: Enlarging an existing hole.

• Knurling: Creating a pattern of small ridges on the surface of the workpiece.

• Parting: Cutting off ...read more

Rolling process is a metal forming process in which a metal stock is passed through a pair of rolls to reduce its thickness and increase its length.

• Rolling process is used to produce sheets, plates, bars, and other metal products.

• The rolls used in the process can be either flat or grooved.

• The process can be hot rolling or cold rolling depending on the temperature of the metal being rolled.

• Hot rolling is used for metals...read more

The melting point of steel varies depending on the type of steel, but generally ranges from 1370-1530°C.

• The melting point of steel can vary depending on the specific alloy and composition.

• Carbon steel typically has a melting point of around 1370-1480°C.

• Stainless steel, which contains chromium and nickel, has a higher melting point of around 1510-1530°C.

• The melting point of steel is important in the manufacturing proces...read more

Steel is an alloy of iron and carbon, while stainless steel contains iron, carbon, and at least 10.5% chromium.

• Steel is more susceptible to rust and corrosion than stainless steel.

• Stainless steel is more expensive than regular steel.

• Stainless steel is commonly used in kitchen appliances, medical equipment, and construction.

• Steel is commonly used in construction, automotive, and manufacturing industries.
