| Macrostructure and pollution |
The macrostructure of the workpiece on the other 14-1-3159-81 (when checking for cross etched Templeton) should not be visible without using the magnifying devices podnasadochnogo looseness, cracks, foreign non-metallic microflute, cellular and subcortical bubbles, bundles. The defects allowed must not exceed: on a point inhomogeneity 2 points, according to the Central porosity - 2 points, exudation square - 2 points. Contamination of the metal blanks must not exceed 2 points - sulphides, oxides, stroke, non-deformable silicates, plastic silicates; 3 points - nitrides and carbonitrides. |
| Microstructure |
The contents of alpha phase in the billet on the other 14-1-3159-81 should not exceed 2.0 points. |
| Features of heat treatment |
Steel products for equipment of chemical industry termoobrabotannyj according to mode: heating to 1050±20 °C, the holding time at the heating for hardening to products with a wall thickness up to 10 mm - 30 min, over 10 mm - 20 min + 1 min per 1 mm max thickness cooling products with wall thickness up to 10 mm in the air, over 10 mm in water. |
