ALTA SPECIAL STEEL supply DIN 1.2344 / AISI H13 in round bar, plate, square, sheet and block.

Chrome–molybdenum–vanadium-silicon steel for hardening in oil and in air with very good hardenability (the steel is hardened in the whole cross-section up to the diameter of about 150 mm), high firmness during the heat and resistance to the tempering and the wear (higher than by the steel 1.2343), very good toughness and plastic properties during normal and also higher temperatures. Further the steel has a very good resistance to tearing of thermal fatigue (lower than by the steel 1.2343) and higher sensitivity to quick changes of temperature than by the steel 1.2343. The steel is suitable for the heat treatment also for firmness over 1765 N/mm2 and for tools cooled by water. It is well-workable during the heat and well-workable in the soft-annealed state.
