Why Choose Tianyou Spare Parts?
Precision manufacturing for ultimate pelleting performance.
Deep Carburization
Advanced carburizing heat treatment achieves HRC 58-62 surface hardness while maintaining a tough inner core, providing extreme wear resistance against abrasive wood fibers.
CNC Gun Drilling
Precision gun-drilled holes with controlled geometry ensure consistent pellet density and maximum throughput for hardwood and softwood biomass pelleting.
Reinforced Blank Forging
High-pressure forged blanks eliminate internal metallurgical defects, preventing catastrophic die failure during high-pressure biomass compression.
Premium Material & Extended Lifespan
Forged from high-grade X46Cr13 (Stainless Steel), our replacement ring dies and roller shells offer superior resistance against corrosion and abrasive wear during high-temperature pelleting. Processed through advanced vacuum heat treatment, we ensure a uniform hardness (typically HRC 52-56), which maximizes output capacity while minimizing the cost per ton of feed produced.
Frequently Asked Questions
Why use stainless steel for wood pellets? ▼
Wood pellets produce acetic acid and resin during pelleting. X46Cr13 stainless steel resists this corrosion, extending die life compared to carbon steel in biomass applications.
Is this die suitable for hardwood sawdust? ▼
Yes, our stainless steel die handles both hardwood and softwood sawdust. For highly abrasive materials, we also offer alloy steel versions with higher wear resistance.
为什么材质至关重要
环模的使用寿命取决于其材料成分和热处理工艺。我们仅使用经过认证的X46Cr13不锈钢和20CrMnTi合金钢，通过真空热处理确保硬度均匀和最大耐磨性。
