hardox 500 chemical composition hot rolled plate production line

On Nov. 1st, 2019, BBN HARDOX 500 chemical composition steel organized Delegation to visit Zhengzhou Children Welfare Institute, and to give sponsorship as well as concerns to the Children. The handicapped children is always a pain topic. With the development of the society, they also gets increasing concerns and help from all walks of life. Thankfully, our Government also gives high concern to the handicapped children and has built HARDOX 500 chemical composition Children Welfare Institutes all over the country to guarantee their lives.

The final heat treatment of quenched and tempered alloy steel, HARDOX 500 chemical composition is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.
