I would like to ask everyone: does anyone know what material P5 is made of? I found online that P5 refers to CrMo heat-resistant steel pipes. What welding materials should be used for welding this material, and what is the welding process? What welding material should be used for welding with 20#? ? ? Urgent need, please help resolve this. Thank you! ! !

The composition of this material is as follows: Cr 4.64； Mo 0.49 ； Is Fe 94.23 this material? I haven’t been exposed to it before

Use R507 electrode; perform TIG welding for the root pass and SMAW welding for the fill and cap passes. Preheat before welding, and carry out heat treatment immediately after welding. When welding with 20# steel, it is recommended to use A307 welding rods.

I believe it is better to use carbon steel welding materials
