Material datasheet for steel 1.2345

This material is 5% chromium hot work tool steel designed particularly for applications requiring extreme toughness combined with good red hardness. It provides an extra margin of safest in tools subject to heavy hammer blows, and those tools containing deep recesses or sharp corners. While is has been designed primarily as a hot work tool steel, it has been used in many cold work applications where extra toughness is required at the sacrifice of some wear resistance.

It has been used primarily for tools requiring resistance to softening at elevated temperatures. Such tools include forging dies and punches, die-casting dies, aluminium extrusion dies, hot heading dies, piercing and forming punches, etc.
