Uns T30102 Steel Exhibits Excellent Dimensional Stability - China

UNS T30102 steel (i.e., A2 tool steel), thanks to its air-hardening properties and alloy composition design, exhibits minimal deformation during heat treatment, allowing it to stably maintain precise dimensions and tolerances.

This makes it an ideal material for high-precision applications such as precision molds and gauges.

Core Principles and Composition Support:

1 - Air-hardening nature: Alloy elements such as chromium (4.75–5.5%) and molybdenum (0.9–1.4%) enhance hardenability, allowing for martensitic transformation through air cooling alone, eliminating the severe thermal shock of oil/water quenching and significantly reducing thermal stress and deformation risks.

2 - Microstructure stability: Carbon (0.95–1.05%) ensures hardness, while vanadium (0.15–0.5%) refines grain size and inhibits tempering softening.

The low residual austenite content after quenching results in minimal dimensional drift during subsequent aging and use.

3 - Thermal expansion matching: The balanced composition ensures a stable coefficient of thermal expansion, resulting in uniform and predictable deformation during heat treatment and service temperature changes.

The exceptional dimensional stability of UNS T30102 steel stems from the synergistic effect of its air-hardening properties and alloy composition.

Its advantages can be maximized through standardized heat treatment and processing techniques, making it particularly suitable for precision manufacturing fields requiring high dimensional accuracy and consistency.
