S235J2

Low temperature impacting test shall be done for structural steel plate S235J2 under minus 20 centigrade.When rolling of steel plate S235J2,As rolled or Normalizing rolling is both ok.As rolled delivery condition without any special rolling and heat treatment condition.Normalizing rolling process in which the final deformation is carried out in a certain temperature range leading to a material condition equivalent to that obtained after normalizing so that the specified values of the mechanical properties are retained even after noamalizing. Full Data Technical Requirements & Additional Services:
♦ Low temperature impacting test
♦ Rolling under standard NACE MR-0175 (HIC+SSCC)
