DIN 1.2344

Thermal Stability

Dimensional shifts in die casting or injection tooling decrease when utilizing this grade due to its secondary hardening characteristics. The presence of molybdenum and vanadium allows the matrix to retain hardness at elevated temperatures, preventing the deformation common in simpler carbon steels. Tooling manufacturers specify this grade for inserts and cores that encounter abrasive resin flow or high injection pressures.

Cooling channels drilled into this alloy maintain structural integrity despite the localized heat flux of repeated cycles.

Processing Compatibility

Machinability of din 1.2344 remains consistent in the annealed state, allowing for precise milling of complex geometries before hardening heat treatments. Fabricators reach the desired hardness range through quenching and multiple tempering stages to ensure a stable microstructure. Regrind material usage demands caution because high-speed steel performance relies on specific alloy ratios that shift if the feedstock suffers from excessive oxidation during previous melt cycles.

Incorrect hardening parameters result in brittle components that fracture under the cyclical stress of mass production.

Cost Efficiency

Lifetime performance of the mould determines the actual expense of selecting this specific alloy. High initial procurement costs diminish when compared to the frequency of replacement for components made from lower grade steel. Mould failure occurring mid-run incurs downtime expenses exceeding the price difference between tool steel grades.

Longevity of the tool surface minimizes the need for frequent polishing or repair, stabilizing the unit cost per moulded part.
