GRINOX 307 E307-16
CLASSIFICATION
AWS/SFA 5.4: E 307-16, DIN 8556 : E18.8Mn R26
DESCRIPTION
Heavy coated rutile type electrode manufactured using stainless steel core wire depositing fully austenitic weld metal. The non-magnetic weld metal is extremely unsusceptible to cracking and possesses high deformation capacity so that stresses are equalized and relieved. Under mechanical loading, the weld metal is inclined to work harden. It resists corrosion and scaling. The deposited weld metal meets x-ray / radiographic quality code requirements. The weld metal can be PWHT without risk of sigma phase formation and consequent loss of ductility.
