So welding consumable shall be procured according to it.   Exemptions of Production Hardness is permitted if below consumables are used.                                                                                                                                                                 & nbsp;            The Electrode/Filler metal requirement in accordance to NACE MR0175 for carbon steels.     The welding consumable shall produce weld Zones meeting Hardness requirement of 250HV10. The Nickel in the welding consumable shall be less than 1%. Welding consumables and procedures that produce a deposit containing more than 1% nickel are acceptable after successful weld SSC qualification by testing in accordance with Annex B.     ** As an alternative, one can consider proper Preheating and PWHT methods to control Hardness.                                                                                                                                                             & nbsp;                                                                                              Thanks & Regards   ----------------------------------------------------------------- J.Gerald Jayakumar Senior Engineer-Technology Equipment Engineering (Materials & Welding) Foster Wheeler India Pvt Ltd Chennai Execution Centre Landline : 0091-(44)-66769047 Mobile    : 0091-9344954677 ---------------------------------------------------------------   Confidentiality Notice This communication and the information it contains:- (a) Is intended for the person(s) or organisation(s) named above and for no other person(s) or organisation(s).
