Steel and types of steel

 Steel:

Steel is composition of carbon and iron in fixed ratio below 1.5 % carbon available in steel alloy 

There are some types of steel available 

1.Dead mild steel 

2. Low carbon steel 

3. Medium carbon steel 

4. High carbon steel 

5.special steel 

6. High speed steel 

Dead mild steel:  

In this composition of carbon  is below. 0.015 %   and remaining iron. Used for sheet metal, rod, etc. 

Low carbon steel: 

0.015 -0.3 % Carbon present   in this composition and remain iron 

Medium carbon steel : 

0.3- 0.8 % of carbon present in this composition used in crane hook, hammer, iron rod,  etc

High carbon steel: 

Carbon present 0.8-1.5 % and remain iron

It is used in tool as chisel and hammer, cutting tool, etc. 

Stainless steel : 

It is special alloy steel which is composition of chromium and carbon, iron. Chromium used for corrosion prevent element and increase hardness. 

High speed steel :HSS

It s composition of chromium tungsten and iron and carbon. There fixed composition is 18:4:1 where is 18% is chromium , 4% vanadium and 1% tungsten. 


Thanks

Continuity equation & types of flow |FLUID MECHANICS ||PART -4

Image
Basic terminology of fluid mechanics  Steady flow : In this flow velocity of fluid particle don't change with time at fixed point of fluid is called steady flow. Unsteady flow: In this flow velocity of particle change with time at fixed point of fluid is called unsteady fluid . Uniform flow : In this flow the magnitude of flow don't change (same ) at point of fluid . Non-uniform flow: In this flow the magnitude of flow  change (different) at point of fluid . Laminar flow :   In this flow fluid particle move in smooth and regular in motion is called laminar fluid is called laminar fluid and it is also  called steam line flow . Turbulent flow :   In this flow fluid particle move in randomly  and irregular  in motion is called laminar fluid is called laminar fluid. Continuity equation : According to this law the inlet fluid is equal to outlet fluid this law based on the conservation of mass . Q = p.A.V   Where the Q is discharge of fluid and p is...

CASE STUDY at ZOMATO

Image
Case study at zomato :   Zomato initially named as Foodiebay was started in 2008 by Mr. Deepinder Goyal. It is a restaurant searching platform providing in-depth details with autonomous reviews and ratings. Foodiebay, the initial name was changed to Zomato in November 2010 to increase their reach among people. To differentiate themselves from their competitors, Zomato concentrated on adding approx. 18,000 new places to eat from. Along with they also decorated many special features, such as pointed to particular dishes or opening times”. To be the largest resource in food supply market, Zomato bought urbanspoon, a leading restaurant service providing portal for $52 million to enter US, Canada and Australia to leverage local insights and experience and to expand their business in overseas seeing the future goal and objective.   To expand to more 50 countries Milestones: Number of listed restaurants: in 2008 it was 4000 restaurants which increase to 94000 in 2013 and current...

Interview questions for mechanical engineering

Q.  What is elasticity?  Ans. It is the propertyof material where apply deforming force on the body  so body is deformed,  it will regain its original shape after removing deforming force.  Q. What is plasticity?  Ans. It is the property of material where apply deforming force on the body so it will permanently deformed after removing deforming force.  Q. What's brittleness?  Ans. It is the property which is distortion  of material when applying impact load  or it will break in small parts.  Compressive strengh is high and tensile strength is low.  Q. What is creep?  Ans. It is the property of material which have slow permanent deformation  within temperature along long time.  It's occure in belt  Q. What's toughness?  Ans.is the property of material,Which is resist the high impact load for short time. That is callled toughness.  Q. What's Malleability  ??  Ans.  It the property of m...
