How do you increase the toughness of steel?
As-quenched, martensitic steel is strong, but often notably brittle. In order to increase ductility and toughness, martensite is heat-treated by a process called tempering1,2,3. Strength typically decreases with increasing tempering temperature and time, and a corresponding increase in toughness is expected.
How do I test my hardness?
A hardness test is typically performed by pressing a specifically dimensioned and loaded object (indenter) into the surface of the material you are testing. The hardness is determined by measuring the depth of indenter penetration or by measuring the size of the impression left by an indenter.

Is Hard Water Safe To Drink? Drinking hard water is generally safe. In fact, it may actually be beneficial towards your health. The benefits of hard water include fulfilling your dietary needs of essential minerals, such as calcium and magnesium.
What is better soft or hard water?
Soft water is low in the minerals (especially calcium) that hard water in abundant in, but has a higher sodium content. It is also less corrosive than hard water. However, soft water drinking is worse than hard water due to its low mineral content and offers little health benefits in that respect.
Is boiled hard water safe to drink?
Since boiling removes the water’s calcium content, the result is softer water. Boiling is a quick and cheap way to fix hard water for consumption purposes. However, it only addresses temporary hardness and not permanent hardness. The latter contains dissolved calcium sulfate that boiling will not remove.
Is bottled water hard or soft?
Bottled water is naturally soft, thanks to low levels of calcium and magnesium. Higher levels are often found in municipal water, which is often “softened”—particularly in the United States—to be used at home.
