  • Why are thermo mechanically formed steels so popular for

    Why are thermo mechanically formed steels so popular for piping? The commercial advantage is that a lower C% (and according C equivalent) of TM steels is favorable for welding. However, during welding, the zone surrounding the weld is no longer of the high, TM quality but is locally transformed, quite possibly coarse grained steel with
