GRIBINOX 308LT

IDENTIFICATION : GRIBINOX 308LT E 308L-15
CLASSIFICATION :AWS/SFA 5.4 E 308L-15; IS: 5206 : E 19.9 LB 20

CHARACTERISTICS :

A basic coated stainless steel electrode with a controlled composition and low ferrite content, designed for cryogenic service requiring > 0.38 mm charpy lateral expansion at minus 196°C. The electrode has excellent arc stability and low spatter loss. The electrode can be manipulated easily in all welding positions. The deposited welds are of radiographic quality.

APPLICATION :

  • For cryogenic applications involving use of stainless steels types AISI 304, 304L etc.
  • Food, Brewery and chemical process vessels pipelines and nuclear engineering.
