Rose said: (Aug 6, 2013)  
What is the meaning of puddled iron?

Gvdeepthi said: (Aug 13, 2013)  
Wrought iron is an iron alloy with a very low carbon (0.1 to 0.25) content in contrast to cast iron, and has fibrous inclusions, known as slag.

Engr. Imran Ali Depar said: (Jan 2, 2014)  
What are the benefits of this wrought iron?

K.Siva Prakash said: (Jan 7, 2014)  
Iron metal is used to making building sheets.

Benisa said: (Jan 16, 2014)  
Wrought iron is iron of carbon content 0.1 to 0.25 in compared to cast iron.

Historically it was called as 'commercially pure iron', whether nowaday a current standard for a pure iron is `carbon content of 0.008/wt.

Wrought iron can be made using following process.

*bloomery process, osmond process, finery process, potting and stamping process, pudding process.

Sainajamsheer said: (Mar 21, 2014)  
In low carbon steel carbon content is about 0.1 to 0.25.

Medium carbon steel about 0.25 to 0.7.

High carbon steel about 0.7 to 1.5.

What is the slag ?

Vijay said: (May 13, 2014)  
Slag is an waste and byproduct of iron ore.

Amit Karn said: (Jun 28, 2014)  
What are the types of iron with its iron content?

What are their uses in practical scenario?

Sk Naser Ali said: (Aug 23, 2014)

Yadnesh said: (Sep 18, 2014)  
Wrought iron is an iron alloy with a very low carbon (0.04 to 0.08%) content in contrast to cast iron (2.1% to 4%).

Ahzaz said: (Nov 12, 2014)  
What are the types of steels?

Lakshay Bhasin said: (Mar 12, 2015)  
What do you means by wrought iron?

≪3Civil said: (Mar 12, 2015)  
1) Cast iron:

It is an alloy of iron, carbon and silicon and it is hard and brittle. Carbon content may be within 1.7% to 3% and carbon may be present as free carbon or iron carbide Fe3C.

2) Wrought iron:

This is a very pure iron where the iron content is of the order of 99.5%. It is produced by re-melting pig iron and some small amount of silicon, sulphur, or phosphorus may be present. It is tough, malleable and ductile and can easily be forged or welded.

3) Steel:

Steel is basically an alloy of iron and carbon in which the carbon content can be less than 1.7% and carbon is present in the form of iron carbide to impart hardness and strength. Two main categories of steel are (a) Plain carbon steel and (b) alloy steel.

Anshuman Yadav said: (Mar 16, 2015)  
Wrought iron content in to cast know as slag building sheets.

Soham Deshmukh said: (Apr 15, 2015)  
This answer is wrong according to Wikipedia. The correct one is 0.08 % which isn't mentioned in the options.

Amardeep Kumar said: (Apr 21, 2015)  
Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%), and has fibrous inclusions known as slag up to 2% by weight.

Rajesh Sinha said: (Jun 18, 2015)  
Wrought iron is iron contain low carbon. It can be easily molded.

Avi Shrivastava said: (Sep 18, 2015)  
Wrought iron contain less than 0.08% carbon.

Mahesh said: (Jan 23, 2016)  
Why soil have shear strength?

Civil said: (Feb 26, 2016)  
All properties of soil depends on the stress applied on its surface. When we apply high stress on its surface for example on sand, the soil particles just moves but not affected.

Aravindh Yaadhav said: (Aug 11, 2016)  
Shall I know the types of a steel and carbon content?

Deepak Sharma said: (Nov 25, 2016)  
@Soham Deshmukh.

Answer is correct because .08% is always less than .25%.

Asaithambi said: (Dec 14, 2016)  
Low carbon steel(or)mild steel = 0.05% to 0.25%.
Medium carbon steel = 0.25% to 0.75%.
High carbon steel = 0.75% to 1.5%.

Anant said: (Jan 18, 2017)  
What do you meant by wrought iron?

Tinsae said: (Jan 25, 2017)  
Wrought iron is an iron type which is pure and have a low carbon content up to 0.25%.

Prasant said: (Feb 7, 2017)  
In construction industries which iron widely use?

V.Sivakumar said: (Apr 11, 2017)  
In desin of steel structures book - N.Subramanian.

The range of carbon up to 0.20%.
CAST IRON - 2.5-4.5 %.
STEEL - 0.1 - 1.1% OF CARBON But Here the Answer is 0.25%.

HOW?

Keshav Raidas said: (Jun 9, 2017)  
MATERIAL ------- CARBON CONTENT IN %.
WROUGHT IRON ------- 0.02 to 0.03.
MILD STEEL ------- 0.1 to 0.3.
CAST IRON ------- 2 to 3.
PIG IRON ------- 3 to 4.

Abrar said: (Nov 14, 2017)  
Wrought iron is the purest form of iron and contain carbon in less amount about 0.15%. According to R K Rajput Engineering materials.

Udaya Kumar said: (Feb 12, 2018)  
In Construction industries, mild steel is used.

Rabindra said: (Apr 10, 2018)  
Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%).

It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion-resistant and easily welded. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name wrought because it was hammered, rolled or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild or low carbon steel. Neither wrought iron nor mild steel contains enough carbon to be hardenable by heating and quenching

Vishal Pandya said: (Apr 18, 2018)  
Yes, @Abrar.

It is 0.15%.

Ghanendra Kumar said: (Apr 20, 2018)  
No @Yadnesh.

The low wrought iron range varies 0.1 to 0.25%. Thank you.

Divyesh said: (Jun 13, 2018)  
What is the answer of max Carbon content allowed in mild steel, to be used in sheet metal for construction?

Rajitha said: (Sep 8, 2018)  
What is bloomery process and what is it's use?

Surendra Dangi said: (Oct 20, 2018)  
High carbon steel =0.8 -1.5.
Medium (high tensile)=0.3-0.8.
Mild =0.15-0.3.
Dead mild= less 0.15.

C.I and Pig iron - 2 to 5%.
Steel - 0.5 to 1.5%.
W.I - 0.1 to 1.25%.
Mild steel - less than 0.25.
