Development and property analysis of ultra-low carbon self-shielded flux-cored wire with nitride solid solution strengthening

Ultra-low-carbon 00Cr13Ni4MoN series self-shielded flux-cored wires using nitrogen solid solution strengthening were deveopled.The wires have excellent welding usability and mechanical properties.The microstructure of the deposited metal is nearly single martensite,which possesses temper-resistant softening property,toughness and resistance to wear.
