Factors affecting the quality of BP440 bulletproof yield strength

"As Covid 19 spreads around the world, all unnecessary businesses and factories have been closed in Italy this week. South Korea's POSCO, the world's fifth-largest steelmaker, announced on March 24th that it would close its BP440 bulletproof yield strength wire-processing centre near the northern Italian city of Verona from Thursday March 26th until April 3rd. POSCO has already closed two wire-processing centres in Delhi and Pune. Two wire processing centers in Malaysia and Thailand also announced last week that they will be closed until March 31."

40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. BP440 bulletproof yield strength, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.

Phosphorus is a very harmful element in BP440 bulletproof yield strength steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of BP440 bulletproof yield strength steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
