a573 grade 70 high strength structural steel heavy plate 10cm thikness spot

On Jan. 31, 2019, BBN steel held the annual meeting with all employees, family members, and friends. It is a moment of joyand it is a moment to summarize the past and look forward.Looking back on 2018, BBN steel exported a573 grade 70 high strength structural steel more than 2 million tons of steel materials to all parts of the world and made outstanding contributions to infrastructure construction at home and abroad. In 2019, BBN steel will make persistent efforts and forge ahead.

The sensitivity of high temperature tempering brittleness of wear-resistant plates is generally expressed by the difference between the toughness and brittleness transition temperature of the toughened state and the embrittlement state. The more serious the brittleness of high temperature tempering, the higher the proportion of the fracture surface along the grain of the wear-resistant steel plate, a573 grade 70 high strength structural steel. The effect of the elements in the wear plate on the high temperature temper brittleness is divided into two aspects. One is the impurity elements that cause the high temperature temper brittleness of the wear plate.
