S20A (1250℃×3h water quenching) metallographic diagram
The process of water quenching is used to harden steel. Water quenching hardens the steel by improving its strength and structural integrity by forcing the molecules of the steel to become more rigid and densely packed together. This makes it more resistant to wear and tear, ultimately making it la......
