6.Edit GB5216-85 to guarantee the technology of hardenability structure steel
7.The results indicated: Steel with stable chemical composition, oxygen content bellow 0.0020%, and low nonmetallic inclusion, hardenability band≤6HRC, were produced.
8.By experiments of backfire brittleness and stability of low C steel, we knows that adding Boron into the mixing alloy will increase the backfire brittleness and stability of low C steel.
9.The Effect of Alloying Elements on the Continuous Cooling Transformation Diagrams and Hardenability of Medium Carbon Si-Mn-Mo-V Steels
10.Ti, Al and B increase notably the hardenability of the core of 18CrMnB steel, but their effect reduces with the increase in carbon content of carburized layer, and their beneficial effect disappears when carbon reaches to 0.5%~0.6%.
