SAL STEEL Interview Questions and Answers

The method of determining the N/10 factor of K2Cr2O7 involves titrating it against a known concentration of a reducing agent.

• Prepare a solution of K2Cr2O7 of known concentration (N/10)

• Titrate the K2Cr2O7 solution against a reducing agent of known concentration

• Calculate the N/10 factor using the volume of the reducing agent used in the titration

• The N/10 factor is the ratio of the normality of K2Cr2O7 to the normality of

Filtration is a method used to separate solids from liquids or gases using a filter medium.

• Filtration involves passing a mixture through a filter medium to separate the solid particles from the liquid or gas.

• Common examples include using filter paper in a funnel to separate sand from water, or using a coffee filter to separate coffee grounds from brewed coffee.

• Different types of filtration methods include gravity filtr...read more

Iron carbon diagram shows the phases of iron and carbon at different temperatures.

• Iron carbon diagram is a graphical representation of the phases of iron and carbon at different temperatures.

• It helps in understanding the microstructure of steel and cast iron.

• The diagram shows the phases such as austenite, ferrite, cementite, and pearlite.

• It is used in heat treatment processes to control the properties of steel.
