Why heated for ASTM steel pipe

One kind of steel pipe can be made by different original materials as well as production process. And all these steps would finally lead to the different characters of seamless steel pipe or welded one. And today we would have a discussion for why heated for

Steel pipes can be heat treated or non heated treat. And the ASTM guidelines cover the details of the treatment process and set a hardness scale. Why ASTM steel pipe would adopt the heat treat method? More rigid and stronger than other welded steel pipe like SSAW steel pipe and so on would be one of the benefit. Of course, it is also removing the internal stresses and weaknesses which are part of the steel as a result of the shaping processing. Heat-treating is characterized by over 50 different terms which describe the internal changes, how the steel acts and the steel’s appearance after the treatments.
