Steel is harder than gold. This is a alloy composed of iron and C (carbon), Si (silicon), mn (manganese), P (phosphorus), S (sulfur), and a small amount of other elements. In addition to FE (iron), the content of C plays a main role in the mechanical properties of steel, so it is called iron carbon alloy. It is the most important and most dosage metal material in engineering technology. Gold (GOLD) is a single form of chemical element gold (chemical element symbol AU). It is a soft, golden, corrosive precious metal. Gold is one of the rare, precious and most valued metals. Internationally, gold is generally based on ounces, and ancient China was used as a gold unit. It was a very important metal. It is not only a special currency for reserves and investment, but also an important material for the jewelry, electronics, modern communications, aerospace and air industry and other departments. The chemical symbols of gold are AU, and the English code in finance is xauusd or GOLD. The name of the AU comes from a story of the goddess of dawn in Roman mythology, which means the shining dawn.
Vajrayana-hardness is 10 (the highest nature is the highest, generally as a relatively standard); bronze-hardness is about 5.1; -raw iron (Fe)-hardness is about 4.5 18k gold- -Drinkability is 4.0 ~ 4.5 (specifically depending on what metal components are the remaining 25%); The higher the carbon content of steel, the greater the hardness (the weak impact of ignoring the alloy element) T12 steel content Carbon 1.2%, 20 steel is 0.2% 65mn is 0.65% 40Cr is 0.4% So hardness is T12> 65mn> 40Cr> 20 n Steel is applicable, if the content of steel alloy is very high.

Gold is soft. You can bite the mark with your teeth. Steel is very hard
Vajrayana-hardness is 10 (the highest nature is the highest, generally as a relatively standard);
bronze-hardness is about 5.1;
-raw iron (Fe)-hardness is about 4.5
18k gold- -Drinkability is 4.0 ~ 4.5 (specifically depending on what metal components are the remaining 25%);
The higher the carbon content of steel, the greater the hardness (the weak impact of ignoring the alloy element)
T12 steel content Carbon 1.2%,
20 steel is 0.2%
65mn is 0.65%
40Cr is 0.4%
So hardness is T12> 65mn> 40Cr> 20 n Steel is applicable, if the content of steel alloy is very high.
Steel is hard. Essence Essence Golden
Steel.
The gold will wear it, the gold jewelry is brought for a long time, and the weight will be reduced.
The steel will not
