Select an alloy designation:

Zone I:

  • Excellent weldability
  • With low carbon content, even with high carbon equivalent, there are no major weldability concerns.
  • No pre- or post-heat treatment required

Zone II:

  • May be difficult to weld without proper heat treatment
  • Generally requires preheat

Zone III:

  • Unweldable without propper heat treatment

IIW Method:
