High Stregth Heat Treated Steel Bar

Heat treated steel bar is kind of steel bar which is heated to a high temperture and then do cooling in different media and temperture. After heat treating, the heat treated steel bar will get different microsture from Hot Rolled Steel Bar. Heat treated steel bar includes Annealed Steel Bar, Normalized Steel Bar and Quenched And Tempered Steel Bar. Among the bars, annealed steel bar is soft which is easy to be machined. Normalized has uniform microsture. quenched and tempered steel bar has high strength.
