Steel is used in various situations.

Sometimes you need hard steel, and sometimes you need tenacious steel.

　　

It is necessary to change the properties of steel according to the usage.

 

In such a case

① Heat treat

 

② Add other elements to make special steel

I will take the method.

 

Heat treatment is explained in detail in the "heat treatment" category.

Please look there.

 

Here are some brief introductions to the elements that make special steel.

・Chrome: A typical function is that it is resistant to rust and wear. The price is also cheap.

・Molybdenum: It deeply burns. Used with other elements. The price is high.

・Boron: Improves the hardenability of steel with a very small amount.

　　　　　　

 

There are also cobalt and tungsten.

It is synergistically more effective to add these little by little than to add many at once.
