The drill bits cannot penetrate the carbon steel pipe plate after surfacing with stainless steel and heat treatment. I don’t understand why – when 16MnIII is surfaced on 316L, it’s difficult for the drill bit to drill. Welcome everyone to participate in the discussion

As the saying goes, stainless steel has high stickiness and is difficult to machine; after cladding the tube sheet, drilling is generally done from the carbon steel side. If it is made of pure stainless steel, the issue of drilling deviation also needs to be considered.
