Product Description

1.2344 flat bar is a highly versatile chromium-molybdenum hot work steel, widely utilized in both hot work and cold work tooling applications. It is engineered to resist thermal fatigue cracking, which frequently occurs due to cyclic heating and cooling cycles in demanding industrial environments.

Key Advantages:
  • Excellent combination of high toughness and resistance to thermal fatigue.
  • Superior stability during heat treatment processes.
  • High resistance to thermal shocking and hot cracking.
  • Competitive performance for heavy-duty mold applications.

Available Sizes:

  • Square/Round Bar: 12mm to 550mm
  • Flat Bar: Thickness from 15mm; Max width up to 1000mm

Common Applications:

1.2344 steel is ideal for aluminum extrusion dies, backers, bolsters, stems, mandrels, die casting dies, and forging inserts.
