CLASSIFICATION:

AWS A5.1: E 7018-1
IS: 814 EB 5629H3JX

DESCRIPTION:

SUNTHERM 7018-1 is an iron powder low hydrogen type electrodes producing a tough & ductile weld metal for welding heavy and rigid structures subjected to dynamic loading and impact. The weld metal is of radiographic quality and displays remarkable impact strength even at - 500 C.

APPROVALS: CIB

TYPICAL ALL WELD METAL PROPERTIES:

Chemical Composition (%) Mechanical Properties
C 0.10 max Mn 0.80-1.60 YS 46-52 kg/mm2
Si 0.50 max S 0.03 max UTS 53-62 kg/mm2
P 0.03 max EL (L=5d) 25-32%
Impact (CVN) at -500C 40-100 Joules

TYPICAL APPLICATION:

Ideal for welding of carbon steels,boilers,frigates & submarines,steels sensitive to hydrogen embrittlement, heavy & rigid structures, pressure vessels and equipment subjected to severe stress and requiring good toughness properties at sub zero temperatures down to – 500C.
