When heated above 10 ° C, a melt of T11 H occurs: it is of the same type and its subsequent evaporation. Example. The original part is steel 4nuk) a sleeve with an inner diameter of 30 mm is installed in the mandrel. A split paraft4 gasket 0 21, 6 mm and thickness, О, 3 mm is marked inside the part. Powder of wear-resistant alloy of SNGN grade (N.S. 58-60) dry up into the gap between the part and gasket, and powder of PG-XH80CP2 grade (HS 34-38) into the gap between the base and the gasket.
