Weldability Automatic submerged arc welding produce austenitic wire for manual two-sided, the back weld of the root and width of the weld pad in the cutting not less than 15 mm.
Macrostructure and pollution The macrostructure of the forgings on the other 14-1-3085-80 should not have traces of shrinkage, porosity, cracks, bubbles, placenow and foreign inclusions visible to the naked eye. Evaluation of the macrostructure is produced in the points e should not exceed: Central porosity ≤ 2.0 points, for all other types of ≤ 1.0 points according to GOST 10243, layer-by-layer crystallization and the bright circuit ≤ 3.0 points according to GOST 10243.
Particularities of production of goods Forgings on the other 14-1-3085-80 are supplied in the annealed condition with hardness not more than 302 HB (indentation diameter not less than 3.5 mm)
Machinability Intractable.
