What is red-shortness in steel?
is the steel which breaks as it's heated to red hot
Can you mill red hot glowing steel?
No machining is advisable when material to be machined is red hot rather it can be forged, extruded. Primary machining only is normally advisable when material is red hot.
Why does cold rolling take more energy?
when making sheets of steel, the steel is smooshed out flatter and flatter many times until it is as thin as you need it to be. If you do this when the steel is red hot, the metal is very soft and easy to smoosh out. If the steel is not red hot it takes a lot more work = energy, to smoosh it out flat.
Can steel be hardened or temperedby heating it till it glows red-hot and then cooling it quickly?
Yes
At what temperature mild steel becomes red hot?
Hey there, have a look at this website: http://www.muggyweld.com/color.html
How do you increase hardness of mild steel?
You heat your object until its hot red and then you cool it quickly in water
When did Red Steel happen?
Red Steel happened in 2006.
How can a low carbon steel be restored to a soft condition how can this part be restored to a soft condition?
It's done by annealing - just heat the steel red hot and allow it to cool on its own.
Is mild steel ductile or brittle?
the tensile strength, hardness and yield strength of steel depends on the amount of carbon in it. this is because amount of pearlite increases linearly with % of C in steel from 0-0.77%. Elongation (ductility) is caused by the ferrite in the steel which forms plastic deformation. there are two ways of treating steel: 1) quenching- this is when red hot steel is rapidly cooled to R.T. this traps most of the carbon in the steel forming pearlite that makes it hard and brittle 2)Normalising- this is when red hot steel is cooled slowly to R.T and allows carbon to dislocate and form ferrite which makes it ductile. this is how mild steel is manufactured.
Why does the steel spoon get hot in liquid?
If the liquid is hot,the spoon get heated because steel is an insulator
How is high-carbon steel hardened?
Heat treating of high carbon steel to harden it is an instantaneous process. The steel is heated red hot, causing the formation of crystals of very hard type of Iron Carbide called "Martinsite". If cooled slowly, the Martensite reverts to iron and carbon again and the steel remains soft. But if cooled rapidly by plunging the red hot steel in water or oil, there is insufficient time for the Martinsite to break down to iron and carbon, and it remains as crystals of very hard Martinsite, imparting hardness to the steel.
Why can steel not be used to make the hot water tank?
You can't use steel to make a hot water tank because steel can rust.
