What is the minimum hardness value for IS 1570 Gr 20C8 material?
The minimum hardness value for IS 1570 Gr 20C8 material is typically around 197 HB.
Does hardness make value?
Hardness can influence value, particularly in materials like metals and gemstones, where durability is a desirable trait. However, value is also determined by factors such as rarity, demand, and aesthetic appeal. In many contexts, including art and collectibles, subjective factors play a significant role in determining worth. Therefore, while hardness can contribute to value, it is not the sole determinant.
What is the hardness of the noble gases?
it has no hardness ohk... then what exactly do you call solid oxygen?
How do you use a Shore scleroscope hardness test?
To perform a Shore scleroscope hardness test, align the indenter tip perpendicularly to the material surface and release it, allowing it to rebound. Measure the hardness reading indicated on the dial on the device. Repeat this process at various locations on the material to get an average hardness value.
What is the hardness of krypton according to the mohs scale of hardness?
Krypton is a noble gas and does not have a hardness value on the Mohs scale of hardness, which is typically used to measure the hardness of minerals and other solid materials. The Mohs scale ranges from 1 (talc) to 10 (diamond), focusing on solid substances. Since krypton is gaseous at room temperature and not a solid material, it does not apply to the scale.
What is the hardness level for en19 material?
approx. 50 HRC after hardening and tempering
What is the equivalent of jis scm440 HQ?
EN19
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
If a material has a hardness of 8 can it not be scratched by a material with a hardness of 7?
Yes, a material with a hardness of 8 can scratch a material with a hardness of 7, but not the other way around. Hardness is a measure of a material's resistance to scratching, so a material with a higher hardness value can scratch a material with a lower hardness value.
Normal hardness value of cast iron used in lathe bed?
In brinell scale ,the hardness value is 180
What is the minimum hardness value for IS 1570 Gr 20C8 material?
The minimum hardness value for IS 1570 Gr 20C8 material is typically around 197 HB.
What is the hardness of bromine?
Bromine's hardness is not typically measured, as it is a liquid at room temperature and does not possess a defined hardness value like solid materials.
What is the hardness for chlorine?
It is a gas so it doesn't have a hardness unless in solid state
How do you determine the hardness of a mineral?
The hardness of a mineral is determined by scratching it with materials of known hardness, such as a fingernail, a copper penny, a steel nail, or a piece of glass. The mineral is assigned a hardness value based on which material can scratch it. This is known as the Mohs scale of hardness.
What is the adjective for hardness?
An adjective--a hard surface.An adverb--work hard.

Describe what would happen if you rubbed a mineral with a mohs hardness value of 7 against a mineral with a value of 5?
The mineral with a Mohs hardness value of 7 (such as quartz) would scratch the mineral with a value of 5 (such as apatite). This is because a mineral can scratch any other mineral with a lower Mohs hardness value.
