Reduction of Area
Reduction of area is caused by strong tensile forces. In addition, the material is weakened at the point of necking.
By refining, the concentration of carbon in the steel can be reduced to achieve softer steel grades.
Rockwell Hardness Test
The Rockwell hardness test method is a quick way to test the hardness of various materials.
Rustproof steel is used wherever steel is exposed to wind, weather, acids and other influences.
