METHOD OF MAKING HEAT EXCHANGER SHELL FROM AUSTENITE STAINLESS STEEL |
| 摘要 |
FIELD: metallurgy.SUBSTANCE: shell is made by rotary extrusion and subjected to heat treatment and machining, i.e. cutting of cooling channels. Said rotary extrusion comprises hardening to reduction of 38.0-45.0% while for better cutting properties annealing is performed in primary recrystallisation process at 780°C-800°C for 30 minutes.EFFECT: better mechanical properties and workability.3 dwg, 3 tbl |
