hardness of BP300 steel copper content

For employees' development,  the company's transformation and development provides employees with a broad career development platform. The company needs "lion-type" entrepreneurial leaders who are full of entrepreneurial enthusiasm and dare to self-renovate. They also need a large number of professional and professional high-quality talents, and employees can get full capacity to display opportunities.

Boiler steel plate hardness of BP300 steel mainly refers to the hot-rolled medium and heavy plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The main boiler steel materials are high-quality structural steel and low-alloy heat-resistant steel. Common boiler steel includes low-carbon killed steel hardness of BP300 steel smelted in open furnace or low-carbon steel smelted in electric furnace, with carbon content WC in the range of 0.16% - 0.26%.

Chemical composition differences between the hardness of BP300 steel, Q345 steel grades (Q345A / Q345B / Q345C / Q345D / Q345E):Q345A steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345B steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345C steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.030，Al≥0.015； Q345D steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.025，Al≥0.015； Q345E steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.025，S≤0.020，Al≥0.015； All the Q345 steel grades contain Nb≤0.07，V≤0.15，Ti≤0.20，Cr≤0.30，Ni≤0.012，Mo≤0.10。
