IDENTIFICATION
GRILOY 43N E430-15
CLASSIFICATION
AWS/SFA 5.4 E430-15
DESCRIPTION
A basic coated hydrogen controlled electrode manufactured using alloyed core wire depositing weld metal having low carbon and about 17% Chromium. The weld metal consists of ferrite and some martensite in the as welded condition. In order to avoid excessive grain growth, the interpass temperature should not exceed 300°C. The deposited weld metal is of X-ray quality.
