E309H-16

309H electrodes contain higher carbon over 309for the welding of austenitic, high carbon 24% Cr –12% Ni stainless steels such as AISI-309-H. The weld deposit of this electrode contains a 0.04-0.08% carbon, which provides higher tensile and creep strengths at elevated temperatures. 309H electrodes have a high deposition rate resulting in excellent efficiency. This electrode may be used in all positions and may be used joint weldsin construction parts for applications like industrial furnaces/ovens, chemical engineering and cryogenic applications. It is also used for joining of dissimilar material.
