Also identify the appropriate materials used for cooking ute

Also identify the appropriate materials used for cooking utensils and how their structure and properties are different from the materials used for rail tracks Estimate how much of this material is needed for producing cooking utensils for worldwide sales

Solution

Answer:

Composition of rail track

Before the development of heat treatment processes, the tensile strength and hardness of naturally cooled rails were controlled by the chemical composition of the steel. Both of these properties of steel depend upon the proportion of carbon and manganese that it contains. Carbon, up to a maximum of 0.82%, and manganese, to a maximum of 1.7%, are needed to produce hard, wear resisting rails

Microstructure

The microstructure of low carbon steel will be made up of ferrite and cementite. The microstructure of rail steel, however, will consist fully of pearlite

Hardness

The typical hardness of a high carbon rail steel is about 280 HB

Tensile strength of Steel used in track

may have a tensile strength from 900 N mm^-2 to over 1200 N mm^-2.

STAIN STEEL USED FOR COOKING UTENSIL

Mixing steel with chromium and nickel (18/8 stainless steel is 18% chromium and 8% nickel while 18/10 has 10% nickel) produces a corrosion resistance steel that is both hard and easy to maintain a shine.

Hardness

The typical hardness is about 150 -400 HB
