Heat-resistant Steel Welding Wire

Our company produces heat-resistant steel welding wire in two types: chromium-molybdenum-vanadium series and chromium-molybdenum series. These wires are characterized by resistance to high-temperature thermal cracking and oxidation.

Our Heat-Resistant Steel Welding Wire is available in two main types: Chromium-Molybdenum-Vanadium (Cr-Mo-V) series and Chromium-Molybdenum (Cr-Mo) series.

Designed for high-temperature applications, this welding wire offers excellent resistance to thermal cracking and oxidation, ensuring reliable performance in demanding environments.
