On Nov. 1st, 2019, BBN 100mm GL-A40 quenched and tempered steel 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 100mm GL-A40 quenched and tempered steel Children Welfare Institutes all over the country to guarantee their lives.
BBN is a big team with great centripetal force. The company adheres to the tenet of "creating value for customers, creating benefits for enterprises, creating wealth for employees, and creating prosperity for society". Adhere to the strict management of factories, technology-oriented, adhering to "standard management, adhere to integrity, the pursuit of excellence, pragmatic innovation "Business philosophy, we are committed to creating a full-process, low-cost, high-quality, green and environmentally friendly stainless steel manufacturing enterprise.
In year 2015, we supplied 950 tons S355J0 angle steel to Egypt government. We have cooperation with local government for more than 3 years. Every year, they would order more than 3000 tons of 100mm GL-A40 quenched and tempered steel steel from our company.
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized 100mm GL-A40 quenched and tempered steel are higher than that of annealed 100mm GL-A40 quenched and tempered steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of 100mm GL-A40 quenched and tempered steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.
Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. 100mm GL-A40 quenched and tempered steel, Q345R pressure vessel steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required. Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel.
Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.
