Heat Treatment Methods for Carbon and Alloy Steel Pipe

Steel pipe generally adopts the integral heat treatment. Heat treatment purposes for steel pipe. The performance of steel material mainly refers on mechanical properties, physical properties, and process performance. Heat treatment will bring different metallurgical structure and corresponding performance for the steel pipe, so could be better applied in different industrial or the oil gas services.
