CLASSIFICATION
AWS/SFA 5.4: E307-15, DIN 8556 : E18.8Mn B20,
IS 5206: E18.8 MnB45
DESCRIPTION
Heavy coated basic 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.

TYPICAL APPLICATIONS
• Specially designed for joining austenitic manganese steel (12% Mn) to Mild Steel.
• For producing crack free joints in difficult steels and high alloy steels including armour plates, steel
castings.
• For surfacing manganese steel joints and crossings, and laying buffer layers on difficult steels before
hardfacing, etc.
REDRYING : 250°C / 2 hrs, max 5 cycles, 10 hrs total.
