Why are steel files generally harder than common metal objects?
If they were softer, they wouldn't be able to file them.
Why is quartz harder than steel?
Why is quartz harder steel
What mineral has a hardness of 5 Mohs scale nad can be scratched by a steel?
apatite, cobalt, zirconium, palladium, tooth enamel, obsidian (volcanic glass)
What is the Hardness of pyrite on mohs hardness scale?
The hardness of the mineral pyrite, or Fool's Gold, is about 6 on the Mohs hardness scale. That's a little harder than a steel knife blade, but not as hard as the mineral quartz
How would a mineral collector determine the hardness of an unknown mineral specimen?
There are two ways. One way is to buy a scratch test kit and follow the instructions. They will tell you to try to scratch minerals of certain hardnesses and find the hardest one it can scratch. For example, if it scratches a mineral with a hardness of 6 but not one with a hardness of 7, the hardness would be between 6 and 7. If you do not have one of those available, you can try scratching common objects. Your fingernail is 1.5, a penny is 2.5, a pocketknife blade is 5.0, window glass is 5.5, a steel file is 6.5, and quartz is 7.0.
Is 316 stainless steel pipe harder than A106 carbon steel pipe?

How do you tell that a rock is flint?
Flint is a common name for a form of sedimentary rock called chert, formed from microscopic siliceous (essentially quartz) skeletons of radiolarians. As such the hardness of chert is 7, which is slighly harder than glass and considerably harder than steel. If it will scratch glass it is likely to be flint. Flint is often mistaken for limestone or marble, which is much softer and will not scratch glass.
What mineral is the harder more rust resistance form of steel?
Dont know it is to hard
Which one is harder glass or iron?
On the Mohs hardness scale glass is harder than steel. Mohs hardness tests the ability of one material to scratch another. Steel is rated 4 to 4.5 and glass is rated at 6 to 7. http://en.wikipedia.org/wiki/Mohs_scale_of_mineral_hardness Glass is harder than steel, but it is more fragile and will break much easier. There are many different ways to measure strength. Here is a wikipedia article about the strength of materials: http://en.wikipedia.org/wiki/Strength_of_materials
What mineral doesn't occur naturally but must be separated from its ore and its harder more rust-resistant form of this mineral is steel?
it is iron
