| Macrostructure and pollution |
The macrostructure of the alloy bars on THAT 14-1-832-73 should be tight with no traces of shrinkage, voids, cracks, slag and nonmetallic inclusions that are visible without using the magnifying devices. |
| Particularities of production of goods |
Bars hot rolled and forged on the other 14-1-832-73 are supplied without heat treatment. |
| Features of heat treatment |
On the other 14-1-832-73 mechanical properties of hot rolled and forged bars (σВ, δ) and specific resistivity (ρ) are determined at room temperature on samples annealed by mode Quenching in water 1050-1100 °C. the testing Results of mechanical properties and electrical-resistivity recorded in the certificate. |
