Tata Steel Construction Engineer Interview Questions and Answers

Types of steel and the steel process

• Types of steel include carbon steel, stainless steel, and alloy steel

• Steel process involves steps like melting, refining, casting, rolling, and heat treatment

• Examples of steel processes are Bessemer process, open hearth process, and electric arc furnace process

Steel is a versatile alloy composed primarily of iron and carbon, known for its strength and durability.

• Steel is an alloy of iron and carbon, with carbon content typically ranging from 0.2% to 2.1%.

• It is one of the most widely used materials in construction, manufacturing, and engineering.

• Different types of steel include carbon steel, stainless steel, alloy steel, and tool steel.

• Carbon steel is the most common type, wi...read more

The hardness scale measures the hardness of stainless steel (SS).

• The most commonly used hardness scale for SS is the Rockwell hardness scale.

• Other hardness scales used for SS include the Brinell hardness scale and the Vickers hardness scale.

• The hardness of SS is determined by measuring the resistance of the material to indentation or scratching.

• Different grades of SS have different hardness levels, which can affect the

Our company uses multiple types of furnaces for different purposes.

• Electric furnaces are used for heating and melting metals.

• Gas furnaces are used for heating and drying processes.

• Induction furnaces are used for melting and casting metals.

• Muffle furnaces are used for high-temperature applications like annealing and sintering.

• Box furnaces are used for heat treating and laboratory applications.

HRC to BHN conversion is possible using a conversion chart or formula.

• HRC (Rockwell Hardness C) and BHN (Brinell Hardness Number) are two different hardness scales used to measure the hardness of materials.

• To convert HRC to BHN, you can use a conversion chart or the following formula: BHN = (HRC - 13.3) * 10.4.

• For example, if the HRC value is 50, the corresponding BHN value would be (50 - 13.3) * 10.4 = 370.8.
