Answer / Pande Rajkumar Ayugyanarayan

To check the quality of steel, several methods can be used, including:

1. Visual Inspection - examining the surface and interior of steel samples to detect defects such as cracks, pits, and inclusions.
2. Non-destructive Testing (NDT) - testing methods that do not damage or alter the physical integrity of the steel sample, including X-ray radiography, ultrasonic testing (UT), and magnetic particle inspection (MPI).
3. Destructive Testing - testing methods that involve destroying or altering the physical integrity of the steel sample to evaluate its properties, such as tensile tests, hardness tests, and impact tests.
