Detailed explanation of seamless black steel pipe materials
Black steel pipes refer to steel pipes without any surface coating such as galvanization. Unlike galvanized pipes, their surface remains untreated but typically undergoes anti-rust treatment. Seamless black steel pipes are primarily made from carbon steel, low-alloy structural steel, and alloy steel, which are directly cold-drawn after processing—without solution heat treatment—resulting in pipes with high strength, excellent reliability, and good machinability. Here's a detailed explanation of seamless black steel pipe materials.
