Why crane hook materia is high carbon steel?
the main reason might be that the percentage of carbon increase the hardness of material (steel ) and ductility would decrease
Why hardenability of plain carbon steel is less?
hardness is defined as a resistance to plastic deformation or penatration.Hardness is defined as the ease with which hardness may be attained by quenching . It is also defined as the ability to develop maximum hardness by quenching.It is the process to have a hardened layer of marten site after quenching and also to have high hardness at same given depth. The material which having low critical cooling rate have high hardenability.The factors which reduce critical cooling rate increase the hardenability.alloy steels have low critical temperature. In plain carbon steels are contain not more than .5% of silicon and 1.5% of manganese.These steels are strong,tough,ductile and used in expensive materials.Increase in hardness and strength in plain carbon steel is depend upon the presence of carbon content.
What causes an elecrtic current to flow in a circuit?
The movement of electron towards the high potential causes electric current to flow in a circuit.
Heat engine utilizes low heat value of fuel or high heat value of fuel?
Heat engine utilizes low heat value of oil and also the fuel oil consumption for IC engine usually based on high heat value of oilby Shyam
What is a set down transformer?
A stp-down transformer steps voltage down from a high value to a low value. Transformers only work with AC.
What is the hardness value for carbon?
the hardness vlaue of carbon very much depends on the value of the hardness of the carbon. if it is a high value then the hardness is high however if it is a low value then it is a low hardness helpful??? :D
What causes denature a protein?
High temperature and PH value
Why hardness is important in metallurgy?
For steels especially, there is a high correlation between hardness and strength. Hardness is also indicative of wear resistance for a material.
What is pseudo hardness?
pseudo hardness interferes to high concentration of sodium ion which interfers with normal behavior of soap.
What is the hardness of 68 HRC mean?
The Rockwell C Hardness system uses "HRC" as a measure of hardness for various materials. A hardness of 68 HRC is extremely high and will most likely be harder than simple steel.
What are chromiums properties?
chroumiums is a high corrosion resistance and hardness
Do I adjust the hardness of a saltwater pool if its high?
Probably the least expensive is to replace some or all of the water(dependind on hardness) with fresh.
What is the full form of hrc in term of hardness?
high ruptured capacity
Why ledeburite hardness more than per-lite hardness plus cementite hardness although ledeburite is per-lite plus cementite?
probably because of different thermal expansion of carbide matrix phase with pearlite or austenite disperses, at cooling a high dislocation density apears in phases, especially deformable one, and this high dislocation density is responsible for higher hardness
Application of highy red hardness alloy?
high speed drill bits
What does 10.9 refer to on a metric bolt?
10.9 on a metric bolt indicates the hardness (or load, tensile strength, and hardness) of the bolt. This is almost as high as they get and is about the equivalent to a grade 8 SAE or USS bolt. 8.8 is also a common metric hardness.
Metamorphic rocks that are non foliated usually have?
High density, hardness, and larger crystals.
