 Heat-resistant steel electrode Series | heat-resistant steel in high temperature chemical stability and sufficient strength, and the ability of resistance to gas erosion. According to chemical composition and microstructure, heat-resistant steel can be divided into pearlite steel, martensitic steel, ferritic steel and austenitic steel. Pearlitic heat resistant steel and martensitic steel in electric arc welding, require the use of different types of welding electrodes. General may be different steel grades and different temperatures were selected.
