Advantages Uns G51300 Alloy Material Hot Rolling Process - China

Advantages of Hot Rolling

1 - High Ductility: At high temperatures (1000-1300°C), the deformation resistance of UNS G51300 alloy material is reduced by over 50%, facilitating large deformation processing.

2 - Improved Microstructure: Through dynamic recrystallization, the grain size can be reduced from 100-200μm in the as-cast state to 20-50μm, significantly improving fatigue performance.

3 - Cost-Effectiveness: Compared to cold rolling, hot rolling consumes less energy (approximately 20-30% less), making it suitable for large-scale production.

4 - Moderate Surface Quality: Although the hot-rolled surface is slightly rough (Ra 3.2-6.3μm), it is sufficient for UNS G51300 alloy fastener applications and can be further optimized through subsequent processing.

Limitations of Hot Rolling: Rough Surface: After hot rolling, the surface may retain oxide scale, requiring additional pickling or polishing.

Limited Dimensional Accuracy: Compared to cold rolling, the thickness tolerance of hot rolling is slightly wider (±0.1-0.5mm).

Cooling control is complex: Improper cooling rates can lead to residual stresses or uneven microstructures, requiring precise control.

Conclusion

The hot rolling process for UNS G51300 alloy material is a journey from high temperature to refined refinement.

Through heating, descaling, rough rolling, finish rolling, cooling, and coiling/cutting, the steel achieves precise dimensions and optimized properties, meeting the demands of high-strength fasteners.

Whether you're pursuing efficient production or superior performance, the hot rolling process can provide reliable support for your project.
