Böhler Thermanit 308 H
Welding stainless steel types with an alloy content between 16 to 21% Cr and 8 to 13 % Ni, with high carbon content. The names 18-8, 19-9, and 20-10 are often associated with filler metals of this classification.

CEWELD 308H has been developed for typical operating temperatures up to 400ºC, and up to 600ºC in the short-term range. It also shows good resistance to general corrosion. CEWELD 308H shows higher temperature and scale resistance than the standard L-type. The microstructure is austenite with approx. 5-10% ferrite.
