1.2329 HOT-WORK TOOL STEEL BAR FOR FORGING DIES

1.2329 tool steel is a German standard alloy tool steel, and the executive standard is DIN 17007-11959. 1.2329 has high strength, toughness, good hardenability and stability against overheating, but has high white point sensitivity and temper brittleness. Poor weldability. It needs to be preheated at high temperature before welding and stress relieved after welding. It can be used after quenching and tempering. It is mainly used for high-strength parts such as aeroengine shafts, shafts, gears ect.
