GETIG 316H

IDENTIFICATION : ER 316H
SPECIFICATIONS : AWS 5.9 ER316H DIN8556 SGX5CrNiMo 19.11

CHARACTERISTICS:

Getig 316H is intended for welding tpye, 316H austenitic stainless steels operating at high temperatures (500 –8000C) under long term creep conditions. The depositied weld metal has improved resistance to general corrosion and pitting resistance in marine and industrial environments.

APPLICATIONS :

Widely used for welding ASTM 316H stainless steels as well as Nb or Ti stabilised stainless steels types 321 and 347 when used for high temperature structural service Thick walled steam piping, super heater headers in power generation platnt, etc.

SHIELDING GAS : Pure Argon 99.99% 6-12 l/min., plus back purge.

WELDING CURRENT : DC ( - )

CORROSION RESISTANCE :

Good resistance to general and intergranular corrosion in the more severe environments. For e.g. hot dilute acids. Good resistance to chloride pitting corrosion.
