GETIG 312

IDENTIFICATION
Getig 312, ER 312

CLASSIFICATION
AWS/SFA 5.9 ER 312 BS2901-90 312S94
DIN 8556-86 WSGX10CrNi 30.9

DESCRIPTION

Getig 312 is a solid stainless steel wire which deposits a 29 % Cr / 9 % Ni austenitic / ferritic stainless steel weld metal with a ferrite content of about 40 FN. The weld metal exhibits excellent tolerance to dilution from dissimilar and difficult-to-weld base material without hot cracking, together with high strength and very good heat and oxidation resistance. Not recommended for depositing welds to be PWHT.

TYPICAL APPLICATIONS

Medium and high carbon hardenable steels. For e.g. tool steels, shafts, gear teeth, free cutting steels.
Dissimilar joints between stainless and high carbon steels. Buffer layer prior to hardfacing with chromium carbide deposits, surfacing of metal-to-metal wear areas, hot working tools.

SHIELDING GAS : Pure Argon 99.99% 6-12 l/min

WELDING CURRENT : DC ( - )

CORROSION RESISTANCE

Good resistance to sulphurous gases at high temperature. Good resistance to wet corrosion upto approximately 300°C.
