What does Fe500 steel mean?

User Avatar
The abbreviation Fe stands for Ferrous material ie iron from which the reinforcement steel bars are manufactured. The reinforcement steel bars used in RCC (Reinforced Cement Concrete) are designated as Fe415 or Fe500 depending on their Yield Strength. (The numbers 415 and 500 tell about this Yield Strength in N/mm2 the bars are designed and manufactured to have.) As per IS : 1786 Yield Stress (also known as 0.2% proof stress) of Fe 500 is 500 N/mm2. So, Fe500 steel means the reinforcement steel rods (or bars) that can safely withstand an Yield Stress of 500 N/mm2.

What to do after BE in metallurgy?

User Avatar
A metallurgist can pursue his education further to M.Tech/M.E. and even can take up a Phd. in a particular subject. Besides that jobs in industries, research institutes and laboratories can also be an option.

Why calcium chloride is added with sodium chloride in metallurgy of sodium?

User Avatar
Because the mixture NaCl + CaCl2 has a lower melting point that NaCl.

What is Vacuum metallurgy?

User Avatar
The melting, shaping, and treating of metals and alloys under reduced pressure that ranges from subatmospheric pressure to ultra-high vacuum. The making, shaping, and treating of metals, alloys, and intermetallic and http://www.answers.com/topic/refractory-metals compounds in a http://www.answers.com/topic/gaseous environment where the composition and partial pressures of the various components of the gas phase are carefully controlled. In many instances, this environment is a vacuum ranging from subatmospheric to http://www.answers.com/topic/ultrahigh-vacuum (less than 760 torr or 101 kilopascals to 10−12 torr or 10−10 pascal). In other cases, reactive gases are deliberately added to the environment to produce the desired reactions, such as in reactive http://www.answers.com/topic/evaporation and http://www.answers.com/topic/sputtering processes and chemical vapor depositon. The processes in vacuum http://www.answers.com/topic/metallurgy involve liquid/solid, vapor/solid, and vapor/liquid/solid transitions. In addition, they include testing of metals in controlled environments.

Types of fabric blinds can be made from materials like cotton or linen. Color fabric blinds that match white walls and brown carpets are beige, tan, and khaki. For bursts of color try a forest or olive green.

What does a rolling offset look like?

User Avatar
rolling offsets are used in the piping and sheet metal (duct work) trades, a rolling offset changes the elevation and locaton of the piping or duct usually by using two fittings to offset around obstacles. rolling offsets are used mostly when you are limited to the size of the fittings in order to change your elevation and location rolling offsets are used in the piping and sheet metal (duct work) trades, a rolling offset changes the elevation and locaton of the piping or duct usually by using two fittings to offset around obstacles. rolling offsets are used mostly when you are limited to the size of the fittings in order to change your elevation and location

Why is there is a jump from metallurgy diploma to BCA and then to MCA?

User Avatar
The BCA is most likely a bachelors degree. The MCA is a masters.

What are the advantages of powder metallurgy?

User Avatar
Much faster production while holding closer sizes. better quality too.

Metallurgy is broadly divided into following branches : 1. Mechanical Metallurgy 2. Physical Metallurgy 3. Extractive Metallurgy These are the basic divisions and these branches are further divided into various sub categories.
Asked in Metallurgy

What are the various step involved in metallurgy?

User Avatar
1. Concentration of the ores. 2. Converting the concentrated ore to its oxide. 3. Extracting the metal from its oxide. 4. Purification of the metal.
Asked in Metallurgy

Is there such a thing as clear metal?

User Avatar
Yes. There are a number of instituitions are researching "transparent aluminium". There are several formulations being investigated, most invove Aluminium oxynitride, a ceramic compound that is transparent. Most research is aimed at using the transparent material as an armour of some sort, e.g. bullet proof glass.

What will happen to steel railroad tracks on a hot day if they were laid out during a cold day without clearance or gap?

User Avatar
When metals become cold, they contract and take less space, but when a metal gets hot, it expands and it will need more space. So, in this case the metal tracks took less space when fitted without gaps on the cold day, but on the hot day the metals will need more space and therefore will push outwards. The tracks will become buckled, and when the train comes, it will go off track.

Why do your rings get bigger when its cold?

User Avatar
Your rings don't get bigger. When the weather is cold your fingers aren't as big as in warmer weather, especially if the weather is humid. During colder temperatures, to conserve heat, your body doesnt send the same amount of blood to the extremities. This can be seen in the ring size difference.

What is metallurgy?

User Avatar
Metallurgy is the art of working metals, comprehending the whole process of separating them from other matters in the ore, smelting, refining, and parting them; sometimes, in a narrower sense, only the process of extracting metals from their ores.

How would you extract lead?

User Avatar
Lead is extracted by reduction of the natural compounds found in its ores. The details depend on the main compound in the ore, but the reduction step is usually smelting with carbon.

Is mild steel an insulator?

User Avatar
No. Mild steel is a fairly good conductor of both electricity and heat.

Is lead now named graphite?

User Avatar
No, it is not. In olden days, graphite was thought to be a form of lead. In fact, it was called plumbago from the Latin name for lead which is plumbum. This is why pencils are still said be lead pencils: they never were.

How much kg of steel need for 10sqft?

User Avatar
None, since there can be no direct conversion. A square foot is a measure of area in 2-dimensional space while a kilogram is a measure of mass. The two measure different characteristics and, according to the most basic principles of dimensional analysis, any attempt at comparisons or conversions between the two are fundamentally flawed.
