| Abstract: | In view of the low impact toughness of 3.5% nickel heavy plate, effect of intercritical quenching On low temperature impact toughness of palte was discussed by experimental study and production practice. The low - temperature impact toughness of 3.5% nickel heavy plate was remakably improved and came up to the high level by means of adjusting heat treatment technology. |
