Weldability of austenitic manganese steel

 · patents for manganese steel was issued to Churchward 1 with the compositions of 1.0–l.25 C and 3.0–13.0 Mn. Other patents have been issued since then but the general trend has been to reduce the carbon content and add some nickel to help avoid martensite formation. The smaller car-bon content was intended to dilute the relatively high

Heat Treatment of Welded JointsPart 1TWI

Normalising. This is a heat treatment that is carried out only on ferritic steels. It comprises heating the steel to some 30-50°C above the upper transformation temperature (for a 0.20 carbon steel this would be around 910°C) and cooling in still air. This results in a reduction in grain size and improvements in both strength and toughness.
