Tempering - The process of reheating hardened steel to some temp. below its critical range in order to decrease hardness and impart toughness is known as tempering. Purpose : 1. To impart toughness to an already...

Lower Critical Temperature All Steel being heated at a uniform rate from room temperature show a comparatively much slow rise in temperature on reaching a temperature about 723 deg. Celsius. This temperature at which a...

High Speed Steel HSS :- HSS removes metal at a much higher rate or speed than ordinary carbon Steel. HSS are categorized by being heat treatable to very high hardness (64 HRC) and of retaining their...

Normalizing ; 1. Refines most part of the steel. 2. To remove internal stresses. 3. Reduce brittleness caused by cold working. 4. Restore toughness of metal reduced by prolonged hot working. 5. To obtain finer grain structure and relatively...

Annealing - Purpose, Process and Effects.  Annealing - Improves softness and ductility in steel and other cold worked metals. Purpose : 1. To induce softness in steel. 2. To remove strain hardening and increase ductility of cold worked...

Gauges - Definition, Types, Principle and other details Gauges - Gauges are checking instruments and they play an important role in ensuring the limits and tolerances for a given component. Gauges are broadly classified as : 1....

Limits, Fits and Tolerance : These three words are one of the most confusing words in terms of their definition. One is linked to the other. In all sorts of interview related to Mechanical these...

Auto Cad Shortcut Keys Auto Cad(Computer Aided Design) is one of the most used design software. Be it any stream in technical sector - Mechanical, Electrical or Civil, this software is used extensively in these...

Cutting Tools in CNC M/cing Cemented Carbide Properties Speed can be 3 to 8 times of HSS Can withstand upto 1000 deg. temp.   Ceramics Consists basically of Aluminum Oxide - 80%, and other oxides of Tin,...

Classification of Hydraulic Turbines Turbines are classified on various basis : A) Head and Quantity of water available B) Name of originator C) Nature of Working of the blades D) Direction of flow of water E) Axis of Turbine Shaft F)...
