In materials engineering contexts, black pipe (black‑iron, uncoated steel) and galvanized pipe (zinc‑coated steel) serve distinct roles. We compare black pipe and galvanized pipe. Both are forms of carbon steel pipe. Black pipe bears an iron oxide finish. Galvanized pipe gets hot‑dip galvanization—zinc‑coated pipe for corrosion resistance. What Is Black Pipe? Black pipe is mild […]

When selecting blade steel, the critical choice between 1055 carbon steel and 440C stainless steel hinges on prioritizing either extreme toughness or corrosion resistance. 1055 (0.55% carbon) delivers superior impact absorption and easier sharpening – reaching HRC 57-60 when heat-treated – making it ideal for survival knives and chopping tools, though it rusts rapidly without
