I use 2520 plates rolled into the pipe, I would like to ask you heroes: what type of welding rod with this? This tube is used on a carburizing furnace, with a temperature of 990 degrees
MG610MG610 is a universal stainless steel welding rod, used in various grades of stainless steel, advanced, all-round welding alloy, high corrosion resistance and high heat resistance, heat resistance temperature up to 1200 degrees. MG610 has good weldability, in a variety of circumstances, a very small splash, and easy to slag removal.Generality：MG610 can be used to weld various grades of stainless steel and carbon steel, especially for welding 310314410430 and similar stainless steels and other alloy steels. Fully austenitic structure means no sigma phase occurs.Application example:Such as: furnace parts, high temperature fan blade, steel ladle, heat treatment container, high temperature pipeline and so onMechanical properties:Tensile strength: 100000 psi / 689 inches per square inchYield strength: up to 65000 psi / 448 inches per square inchElongation 40%Current type: AC/DC+
ERNiCr-3 nickel chromium iron alloy electrode.The welding rod is used for welding nickel base alloy, high temperature and creep steel, heat-resisting steel and low temperature steel, dissimilar steel welding, low alloy steel repair, etc.. Ferritic Austenitic Steel with working temperature greater than +300 DEG C and welding applications without post weld heat treatment. It is suitable for the pressure vessel whose working temperature range is from -196 DEG C to +550 DEG C. It can resist oxidation at +1200 (without sulfur condition). Embrittlement resistance and thermal cracking. When the dissimilar steel is welded, the carbon diffusion at high temperature is low. Thermal shock resistance, corrosion resistance, full austenite structure, between carbon steel and austenitic CrNi (Mo) steel, and lower thermal expansion coefficient.
2520 plate is stainless steel sheet, that is, we often say 310S (American brand), because of nickel (Ni), chromium (Cr) content is high, with good oxidation resistance, corrosion resistance, acid resistance, salt resistance, high temperature performance. The corresponding electrode number is A402 (model E310-16), and the argon arc welding line is HCr25Ni20 (model ER310)
