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.
