Factory Supply H11 Mold Steel Hot Rolling Process - China

H11 mold steel is a high-performance hot-work die steel widely used in mold manufacturing due to its excellent high-temperature resistance, thermal fatigue resistance, and good toughness.

To fully realize the material's potential, the hot rolling process is of critical importance.

Hot rolling not only refines the material's internal microstructure but also significantly enhances its mechanical properties, enabling it to meet the demands of complex operating conditions.

The hot rolling process for H11 mold steel begins with heating the billet.

Typically, the billet is heated to a range of 1100°C to 1200°C to ensure complete austenitization of its internal structure.

This step aims to improve the steel's plasticity and toughness for subsequent rolling while minimizing the risk of cracks or defects.

Precise control over the heating rate and holding time is essential to prevent material degradation caused by overheating or burning.

Next comes the critical rolling stage.

During this phase, the H11 mold steel undergoes multiple rolling passes to gradually shape and size the billet according to specifications.

Roll pressure and speed must be precisely regulated to ensure uniform deformation and high surface quality.

Controlling the rolling temperature is also vital; rolling is generally performed between 900°C and 1100°C to avoid work hardening (caused by low temperatures) or grain coarsening (caused by high temperatures).

Finally, the material undergoes cooling and heat treatment.

After hot rolling, controlled cooling is typically employed to prevent internal stresses or cracking caused by rapid cooling.

Common cooling methods include air cooling, spray cooling, or slow cooling, with the specific choice depending on material thickness and final performance requirements.

Furthermore, to further optimize the microstructure and properties, the hot-rolled H11 mold steel usually undergoes tempering to relieve residual stresses and enhance its overall mechanical performance.
