As a high-carbon chromium alloy steel, TAS features high hardness, wear and corrosion resistance, stable heat treatment performance, good machinability, thermal fatigue resistance, and excellent thermal conductivity. It is suitable for the manufacture of precision molds such as injection molds, die-casting molds, and hot runner systems. During processing, it is necessary to follow the process requirements of quenching at 800–850°C, stress relief by tempering, and temperature control during welding. It is an ideal choice for manufacturing injection molds and die-casting molds.
High-temperature strength is extremely high, and toughness is excellent, which can effectively suppress mold cracking; thermal fatigue resistance is outstanding, and it can withstand frequent temperature changes.
Excellent machinability significantly shortens the mold manufacturing cycle; controlling temperature during welding, combined with preheating and post-heat treatment, can avoid the risk of cracking.
Excellent thermal conductivity maintains a low temperature gradient at high temperatures, reducing the probability of mold deformation and cracking, and is suitable for hot runner and cooling system design.
Tempering treatment can eliminate internal stress, improve toughness, prevent the mold from breaking or deforming under high-strength loads, and result in minimal dimensional deformation.
It meets the requirements of high-strength and high-precision molds, adapts to long-term stable operation under complex working conditions, and ensures service life.
