Welcome to BBN High Strength Steels Factory
Tempering the important S690QL heat treatment welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve S690QL heat treatment strength, plasticity and toughness.
On Nov. 1st, 2019, BBN S690QL heat treatment 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.
