RATNA B Ni 90 (AWS A5.11 ENiCr Mo-6)

Product Specification

A Chemically Basic Flux coated Nickel Based Alloy High in Both Cr and Mo.

 CLASSIFICATION          : AWS/SFA-5.11: E NiCr Mo-6

                                              BS EN ISO 14172

  APPROVAL                   :

CHARACTERISTICS     : Basic coated special welding electrode with high Nickel, Chromium and                                                                       Molybdenum core wire. The electrode suitable for use on DC+ and welding with                                                         smooth Arc and Great arc stability and thus easy control of weld pool with good slag                                                 detachability, 

APPLICATION               : 1) As the weld metal has given excellent cryogenic properties, both toughness and                                                        lateral expansion,

                                            2)  Cryogenic vessels & pipe work of 9% Ni steel for temperatures down to -196°C.

                                            3)  Suitable for ASTM A353, A533, UNS k81340 and K71340.

                                            4) Also suitable for 5% Nickel steel including ASTM A645 and A352 LC4 (cast.)

RE-DRY CONDITION      : Re-Dry the electrode at 350°C for 2 hour before use.
