Jindal Stainless Engineer Trainee Interview Questions and Answers

Hardness is a measure of a material's resistance to deformation or scratching.

• Hardness is often measured using the Mohs scale for minerals or the Rockwell scale for metals.

• Materials with higher hardness values are more resistant to wear and abrasion.

• Hardness can also affect a material's machinability and ability to be shaped or formed.

• Common examples of hard materials include diamond, steel, and ceramics.

Yield point is the stress at which a material begins to deform plastically.

• Yield point is the point on a stress-strain curve where the material transitions from elastic to plastic deformation.

• It is an important property in materials science and engineering as it indicates the maximum stress a material can withstand without permanent deformation.

• Yield point is typically determined through tensile testing of materials.
