| Macrostructure and pollution |
Requirements for the quality of the macrostructure of steel on the other 14-1-2459-78, fracture, surfaces, to the ends of the rods, carbide inhomogeneity, the permissible depth bezoperatsionnogo layer should correspond to GOST 19265. |
| Particularities of production of goods |
On the other 14-1-2459-78 steel shall be supplied annealed with hardness along the length of the rod is not more than 269 HB (indentation diameter not less than 3.7 mm). According to customer's requirement steel made with hardness not more than 255 HB (indentation diameter not less than 3.8 mm). The hardness of the steel after quenching and tempering shall not be less than HRC 63. The red hardness of steel should provide a hardness of at least HRC 58 after a four-hour tempering at a temperature of 630 °C. the red hardness of steel by the manufacturer can not be determined and guaranteed. |
